Abstract

In order to maintain and expand ore supplies base of Belaruskali, which is necessary for the sustainable production of potash fertilizers and to meet the requirements of the world market of mineral fertilizers, the studies of sylvinite ore in new areas of the Starobin deposit are carried out. Among all previously explored areas, the Berezovsky, Nezhinsky and Darasinsky sites are of the highest interest as they are the most studied. Development and improvement of potash processing technology alongside with achieving high qualitative, quantitative, technical and economic standards, as well as enhancement of quality of processing products in the course of changing the raw material supplies base is only possible on the ground of reliable information on the raw materials to be treated. In order to predict production data of processing, in turn, it is necessary to study processability of useful components, i.e. their ability to separate from accompanying minerals and contaminants, including dissociation capacity of grains, floatability and and other preparation characteristics of useful components. The experimental studies on processability of potash ore in the specified areas, which are carried out by means of heavy medium separation and the resultant product analysis, as well as the floatation experiments prove processability of raw materials from the new mining sites of the Starobin deposit by means of floatation of ore from separate mining horizons, or blended with ore from other mines in order to reach high production data (not less than 86 %) of the currently operating flotation factories.
