This work gives the results of researches of absorbent capacity and exchange complex of insoluble residue of clay-salt slimes of Mine Departments of «Belaruskali» JSC. There is defined that absorbent capacity of water-insoluble residue (average in Mine Departments) is 17.4 mEq for 100 g of insoluble residue. Exchange complex consists of cations of K⁺, Na⁺, Ca²⁺ and Mg²⁺. The Ca²⁺ cation has the basic part (to 84 %) in this complex. According to results of researches, there was made a conclusion, that clay-salt slime of concentration plants of «Belaruskali» JSC can be used as structure-forming and fertilizing addition for inefficient Belorusian soils (sands, worked-out peat beds etc) for the purpose of their returning into agricultural use.
