Opis:
Magnetic seeding depression (MSD), i.e. adding organic depressant (such as starch) and magnetic seeds and applying a low field intensity pre-magnetization for depressing target mineral in flotation, was investigated in the reverse flotation of hematite ore slimes. Flotation tests found that the iron recovery increased with the addition of magnetic seeds; the depressing ability of starch in flotation was further enhanced by the MSD. The increased adsorption density of starch on target mineral hematite and apparent size enlargement of fine minerals are two reasons for the MSD. Based on FTIR, VSM and AFM measurements it was demonstrated that the starch acted as a bridging adsorption between hematite and magnetic seeds by hydrogen bonding and chemisorption, and resultant coverage of the magnetic seeds and starch on hematite increased the magnetic susceptibility, being beneficial to the agglomeration of hematite fines by reducing the external magnetic intensity needed for agglomeration to take place. The model of the MSD was proposed.

Opis:
Buildup of magnetic mineral particles on matrices determines the saturated deposit volume of minerals, which is of great importance in the high gradient magnetic separation (HGMS) systems. In this paper buildup of fine weakly magnetic minerals on the matrix is studied with a force equilibrium model. Elaborate rules of particle buildup on the matrix are presented. An imaginary sector ring is used to approximately quantify the volume of saturated particle buildup. The influence of the particle size, magnetic induction, fluid viscosity and velocity as well as matrix size on saturated particle buildup is investigated and discussed. With the same matrix size, the saturated buildup volume decreases with the decrease of the particle size, applied magnetic induction and increase of the fluid viscosity and velocity. The saturated buildup volume normalized by the matrix volume, and the ratio of particle deposit volume to the matrix volume (Vd/Vm) decreases with the increase of the matrix size. Under the same matrices packing fraction, the total mineral deposit volume, when adopting small size matrices, is larger than that when adopting large size matrices. Only small size matrices can be used for recovery of minerals in size of several micrometers. Based on performed analyses, the ore feeding time in a cycle for a cyclic HGMS system and the rotation speed of the swivel for a continuous HGMS system under different circumstances are also discussed.

Opis:
In nickel sulfide processing, magnesium silicates (serpentines) can easily form slime coatings or hetero-aggregation on pentlandite surfaces, and hence decrease the pentlandite flotation rate and recovery. In this work, magnetic separation of pentlandite from serpentine using selective magnetic coating through adding magnetite fines as magnetic seeds was investigated. Interactions of magnetite-pentlandite and magnetite-serpentine were calculated by the DLVO (Derjaguin-Landau-Verwey-Overbeek) theory. The results show that the interaction of magnetite-pentlandite was obviously stronger than that of magnetite-serpentine with an external weak magnetic field (4776 A/m-1). Therefore, fine magnetite fractions selectively adhered to the pentlandite surfaces and enhanced its magnetism, resulting in being separated from serpentine by magnetic separation, which was further verified by magnetic coating-magnetic separation and SEM observations.

In this study, different flowsheet options were evaluated to achieve the best upgrading conditions for a micaceous iron oxide ore. The first option included the recovery of micaceous iron oxide particles using a double stage magnetic separation circuit after the grinding and classifying of the ore into coarse (-1000+106 μm) and fine (-106 μm) size fractions. A belt type dry high gradient magnetic separator (BHGMS) was used to beneficiate the coarse fraction. The concentrate of the BHGMS was ground to -106 μm, and combined with the fine fraction produced at screening stage, and subjected to high gradient magnetic separation (HGMS) at 1.2 T. A concentrate grading about 61.33% Fe with 60.3% recovery was obtained applying the separation process incorporating BHGMS and HGMS. A single stage separation circuit considering the use of HGMS after the grinding the ore below 106 μm was employed as the second concentration option. A concentrate having 63.80% Fe with 37.1% weight recovery was obtained in this test. As the highest Fe grade and the lowest S concentration was obtained by application of HGMS after the grinding the ore below 106 μm, and it was decided to conduct a pilot scale study using pulsating HGMS. A concentrate assaying 69.45% Fe with 60.1% weight recovery was produced by operating the pulsating HGMS at 0.6 T. The results showed that it was possible to obtain a micaceous iron oxide concentrate to be used in pigment production using magnetic separation method.

Opis:
Studying the dynamic behavior of magnetic particle suspensions in the low intensity magnetic separator has important implications for various mineral beneficiation processes. A new approach for fully coupled multi-physics modeling of the dynamic behavior of multi-type magnetic particles (MTMPs) is developed in the study. In this model, the particle tracing module is employed to identify and determine individual particle trajectories in the fluid and magnetic field, which are modelled through the COMSOL Multiphysics. The results show that the different arrangements of the permanent magnet assembly and the volume percentage of interlocked particles affect the dynamic behavior of MTMPs and the efficiency of the separation. The model is compared with experiments and the particle capture theory and the correctness of the solution obtained from COMSOL is demonstrated. The model gives new possibilities to control, optimise, and develop the process of LIMS.

Opis:
Superconducting magnetic separation of chalcopyrite and molybdenite was studied, along with the effects of the magnetic flux density, slurry concentration, and pulsation amplitude on the separation. According to the force equilibrium model of magnetic particles that accumulated on magnetic matrices during the superconducting magnetic separation, the saturated buildup of magnetic particles was calculated. The saturated buildup of magnetic particles was an approximate fan ring and had a positive correlation with the background magnetic flux density. Superconducting magnetic separation tests results showed that a Mo concentrate with a Mo grade of 31.86% and recovery of 87.24% and a Cu concentrate with a Cu grade of 30.57% and recovery of 94.76% could be obtained. This verified the feasibility of separating mixed Cu and Mo minerals via superconducting magnetic separation.

Opis:
Characterization and beneficiation of magnesite-dolomite sample were performed. The role of ore mineralogy in selecting the most adequate concentration method for magnesite-dolomite separation was found to be detrimental. The microscopic analysis showed that dolomite is stained with goethite and lepidocrocite (weakly magnetic minerals), while magnesite is stained with hematite and magnetite (highly magnetic mineral). A dry magnetic separation technique was used to separate dolomite from magnesite. The magnetic separation of the sample resulted in a magnesite concentrate product assaying 1.12% CaO with 46.02% recovery and CaO/SiO2 molar ratio = 1.62. This magnesite product is suitable for basic refractory. Besides, middling fraction was produced, containing 44.63% magnesite and 10.95% dolomite. This product is suitable for making low-loss forsterite dielectrics.

Iron ore tailing is a kind of hazardous solid waste produced by iron and steel industry. In order to separate and recycle iron from the magnetic preconcentrate of an iron ore tailing, an innovative technological route of fluidized magnetization roasting followed by low-intensity magnetic separation was proposed in this paper. The effects of roasting temperature, dosages of reducing gas CO and fluidizing gas N2 on recovery rate of iron were carried out and optimized. The results showed that the hematite was almost reduced to magnetite by a gas mixture of 4 m3/h CO and 1 m3/h N2 at roasting temperature of 540 °C. Under the optimized conditions, a magnetic concentrate assaying 61.4 wt% Fe with a recovery rate of 81.8% was obtained from the magnetic preconcentrate of an iron ore tailing. The iron chemical phase, X-ray diffraction (XRD), and optical metallographic microscope analyses revealed that siderite was converted to magnetite successfully after roasting, and some coarse magnetite-hematite interlocking particles were formed due to insufficient reaction time, which could also be recovered by magnetic separation after liberating from gangue minerals.

Rational use of mineral resources requires advanced separation methods in order to obtain high quality products. In this study chemical treatment with magnetic separation of halloysite from Dunino (Poland) is presented. Initial crushing, hydrochloric acid absorption treatment, sedimentation (settling) and polygradient magnetic separation in weak magnetic field were applied to separate aluminosilicates from iron and titanium oxides (impurities). The process allowed to obtain a product of approximately 98% purity of the aluminosilicate fraction (halloysite + kaolinite). The tailings from magnetic separation consisted of iron oxides, while the intermediate product consisted mainly of aluminosilicate and iron chlorides resulting from the HCl treatment. The obtained products can be used as a component of polymer nanocomposites, sorbents and in ceramics industry.

Opis:
In this work, the effect of magnetite with different particle sizes on the flotation performance of both coarse and fine hematite particles were investigated by using sodium oleate as a collector. The results showed that the magnetite particles with different particle sizes showed a negative effect on hematite (-106+45 μm) recovery, but the addition of magnetite with the same particle sizes as hematite during the direct flotation of -45 μm hematite was beneficial to improve the recovery of micro-fine hematite and the Fe grade of concentrate. The finer the magnetite particle was, the more obvious the agglomeration effect of hematite was. Therefore, the beneficial effect could be achieved by adjusting the particle sizes of particles. Moreover, sodium oleate was beneficial to promote the agglomeration of micro-fine magnetite and hematite. The results from the microscopic analysis, laser particle size analysis, and EDLVO calculation proved that there was an effective aggregation between fine magnetite and fine hematite particles, which increased the apparent size of hematite particles and the probability of the mineral particles adhering to bubbles, thus improving the hematite recovery.

The static magnetic field MF (0.44 T) effects on the adsorption of three surfactants: cationic bromide (DTAB) and hexadecyltrimethylammonium bromide (CTAB), and anionic sodium dodecylsulfate (SDS) from their 10-3 M solutions were studied on bare and low-temperature air plasma treated glass plates. The surface properties of the adsorbed surfactants layers were determined via the water advancing and receding contact angles measurements and then calculation of the apparent surface free energy. An optical profilometer was used to determine the structure and topography of the adsorbed layers. The DTAB and SDS concentrations were below their critical micelle concentration and that of CTAB very close to its cmc. The results showed that in the case of DTAB solution (much below its cmc) a small decrease in the contact angle appeared while in CTAB (close to its cmc) an increase in the contact angle value was observed if adsorbed in the MF presence. Quite good reproducibility of the contact angle values was obtained. This was not the case for the SDS solution where the contact angle values were scattered. The reason was that the anionic surfactant did not adsorb homogeneously on the negatively charged glass surface. The contact angles and the calculated values of the work of water spreading clearly show that MF influences the structure of the surfactant adsorbed layer which was also supported by the optical profilometry images.

The objective of this study was to reduce the contents of iron and titanium heavy minerals of feldspar from Medina syenite ore by a combination of magnetic separation and flotation to obtain the commercial scale of feldspar concentrate for glass and ceramics industries. For the first time, a process flowchart was provided in the light of this study to produce a high-quality K-feldspar product from syenite ore, which meets the requirements of feldspar for glass and ceramics productions. The results reflect that the best performance separation of iron and titanium contents was produced by a dry magnetic separator at 16.000 gauss. The produced feldspar concentrate by magnetic separation yielding 0.54% Fe2O3 with 87% Fe2O3 recovery and 0.57% TiO2 with 16% recovery. The flotation tests were performed on the non-magnetic fraction of the syenite ore. In this stage, the most effective for removal of Fe2O3 and TiO2 from syenite ore was obtained at a 300 g/ton dosage of a mixture of Aeromine 3030C and Aeromine 801 + Aeromine 825 as a collector in an acidic medium (pH 3). The final feldspar concentrate with 0.07% Fe2O3 and 0.06%TiO2 grades was obtained with 89% Fe2O3 recovery and 86% TiO2 recovery. The commercial scale of feldspar concentrate from syenite ore can meet the desired specification of grades 1 and 2 for glass, porcelain, and ceramics industries.

Opis:
Wollastonite plays a significant role as an industrial raw material in many fields; its exclusive properties mean that it is used in ceramics, paint, metallurgy and coatings. In nature, wollastonite mostly occurs with calcite. While the most common method for separating wollastonite from calcite is calcination, flotation is one of the methods for separating two minerals in a more economic, environmentally friendly way. In this study, the ore contains a large amount of calcite and augite, which is an iron bearing mineral that is subjected to magnetic separation, followed by flotation in order to obtain wollastonite and calcite concentrations individually. The SiO2, CaO and Fe2O3 contents in the ore are 28.00%, 48.20% and 0.45%, respectively. After magnetic separation has reduced the iron content, flotation experiments are carried out to find the optimum conditions. For the flotation process, the effect of particle size, pH and collector dosage are investigated. A wollastonite concentration of 84% purity is successfully achieved, with a 0.17% iron concentration under the optimal conditions of 100 micron particle size, pH 8 and 500 g/t collector dosage. The purity of the calcite is raised to 95% with the application of a cleaning stage.

In this study, the iron-rich heavy mineral concentrate production from river sand as a byproduct of an alternative resource by gravity, magnetic separation, and flotation methods were investigated in detail. For the physical separation of the sample and increasing the Fe2O3 content, a shaking table and a wet high-intensity magnetic separator were used, respectively. The gravity and magnetic separation experiments included rougher, cleaner, and scavenger circuits. In the flotation experiments, cationic flotation with ethylenediamine under acidic conditions, and anionic flotation with sodium oleate under alkaline conditions were performed. The iron and silica content of the products obtained were determined by digital image processing (DIP) methods and compared with the classical analytical procedures. Finally, a flow chart was proposed for the processing of the ore according to the optimum enrichment parameters were determined from the experiments. The results obtained in this study show that it is possible to produce an iron-rich heavy mineral concentrate with Fe2O3 grade and recovery rate of 79.13% and 57.81%, respectively, in addition to a potential feed for the production of quartz sand and feldspar concentrates.

The electrochemical deposition of Co-Ni coatings on gold-disc electrode with and without of constant magnetic field (CMF) has been investigated using cyclic voltammetry (CV), scanning electron microscopy (SEM), and energy dispersive X-ray spectroscopy (EDX). The EDX results showed that CMF applied during the electrodeposition of Co-Ni coatings affects their composition. In particular, an increase by 17% in the content of cobalt in coating, i.e. the main component, with a simultaneous decrease of nickel content has been observed when magnetic induction B of 1200 mT was applied compare to this without of CMF. Moreover, it has been supposed that the increase of internal stresses in electrodeposited Co-Ni coatings under CMF can be attributed to a decrease in their thickness.
