Ecological and geochemical characteristics of clay-salt slurries produced with potash ore have been described. A specific feature its composition is high content of soluble chloride minerals, heavy metals, a wide range of organic compounds. It is found that the flotation of potash ores desliming, accompanied by the emergence of various physical and chemical environments (technological geochemical barriers), leading to the accumulation of waste in the trace elements and the formation with its participation organic and mineral complexes. The accumulation of technological chemicals and its transformation products play a major role in organic pollution. There are considered options and processing technologies of clay-salt slurries, to yield a final product of the granular material, which can be used as fertilizer for long-acting and producing isolating geomaterials. Features of changes in composition in contact with water have been investigated.
