ISO brightness - Opis:
- Calcium carbonate is used as an additive in the production of paper and some other production processes. The aim of this study was to determine the chances of the calcite sample to be mechanically cleaned of impurities, so that the material can become commercially interesting, primarily to be sold to the paper and other-related industries. A mineralogical petrographic investigation carried out on a sample of calcite showed that an unfavorable impurity is, in particular, graphite – which is otherwise fairly easily to remove by flotation. Flotation was performed with samples of different particle size. The purpose of this was to find an optimal particle size for carrying out the flotation. In order to achieve an effective flotation results it is first necessary to achieve a proper liberation of grains. The second part of the study was to explore the optimal sequence of treatment procedures for tested calcite, using milling, flotation, and sedimentation.
