摘要

the invention u043eu0442u043du043eu0441u0438u0442u0441u00a0 technology processing potassium ores to obtain u0431u0435u0441u0445u043bu043eu0440u043du044bu0445 fertilizers and enhances the speed of process, while at the same time, ulu u0447u0448u0435u043du0438u0438 product quality through the u043fu043eu0432u044bu0448u0435u043du0438u00a0 u0441u043eu0434u0435u0440u0436u0430u043du0438u00a0 it K2O. according to the invention u043bu0430u043du0433u0431u0435u0439u043du0438u0442 pre u0440u0430u0441u0442u0432u043eu0440u00a0u044eu0442 in water and u043eu0442u0434u0435u043bu00a0u044eu0442 from received u0440u0430u0441u0442u0432u043e ra insoluble impurities.in the solution u0432u0432u043eu0434u00a0u0442 crystalline potassium chloride. in the proposed method the speed of u0443u0432u0435u043bu0438u0447u0438u0432u0430u0435u0442u0441u00a0 1.5 4.5 times, and the content of the K2O u0443u0432u0435u043bu0438u0447u0438u0432u0430u0435u0442u0441u00a0 at 5 - 6% in the absence of insoluble impurities. 1, table 2).
