Opis:
The article presents the results of investigation focused on the utilization of ash and slag wastes (ASW) in Russia including investigation of chemical and physical properties of ASW and processing products. Many factors influence the technological properties of ash and slag materials: naturals, processes and environments. The integrated treatment of ash and slag wastes of both stored and re-formed types will allow obtaining the following commercial products: coal concentrate, iron concentrate, aluminosilicate cenospheres, aluminosilicate product. In this study we have analyzed the methods for separation of ASW iron-containing part using the different types of the magnetic separation from the ash and slag material from one of the combined heat and power plant (CHPP) in the Russian Far East Federal District. The greatest interest is the dry magnetic separation with travelling electromagnetic field. The subject of research was a sample taken from one of ash dump of CHPP in the Far East. In the study iron concentrate containing Fetotal= 64% was obtained recovery 68% in the low intensity (up to 5 kOe) travelling magnetic field.

Opis:
The current state of phosphorus-containing waste and the methods of its disposal remain relevant. The storage of phosphorus-containing waste sludge is carried out in sludge collectors, which occupy large areas. With the disposal of slags and sludge, as well as the elimination of sludge collectors, the harmful effect of waste on the soil will cease, and the possibility of using these areas for economic land use will appear. Many studies show the movement of phosphorus in soil and water, thus proving the difficulty of disposing of this waste. Of course, phosphorus slags and sludge are used in small quantities in the production of building materials, but this does not solve all the problems. In the south of Kazakhstan, there are warehouses for the waste from the production of phosphorus-containing fertilizers, which also require disposal. One of the ways of modern utilization of these wastes is their use in fertilizers for agriculture. However, since the phosphorus-containing waste has a high content of phosphorus, compared to nitrogen and potassium, this ratio can be changed with the addition of chlorella biomass. The purpose of the conducted study was to investigate the possibility of using a complex of phosphorus waste and algae, that is, the cultivation of chlorella at various concentrations of phosphorus-containing waste for further use of the suspension in watering the test plant. In the form of a test plant, tomato seeds were chosen, the cultivation of which in agriculture is economically profitable. When cultivated in closed ground, tomatoes lose their taste, which can be restored with the use of organic fertilizers. This article shows the results of the influence of various concentrations of phosphorus waste and green microalgae on the growth and development of Solanum lycopersicum.
