Research of The Reasons for Decreasing the Degree of Desliming of The Sylvinite Ore of the Tyubegatan Deposit

Abstract

Abstract The purpose of the work was to analyze the work of the first stage of the UE “Dekhkanabad plant of potassium fertilizers” to find out the reasons for the decrease in the efficiency of the process of desliming sylvinite ore of the Tyubegatan deposit. It has been established that the decrease in the efficiency of the desliming process is due to a decrease in the content of potassium chloride and an increase in the insoluble residue in the ore, an increase in the proportion of weakly sludge carbonate and sulfate minerals in the insoluble residue, compared with silicate minerals, a decrease in the differentiated distribution of the insoluble residue in coarse and fine-grained fractions to 1,76, while the design data is 4.22.
