Abstract : Insoluble potash ores of different types from fourteen representative localities are characterized by
microcline as principal mineral phase enriched in potassium. By pretreating the ores with such a procedure as
ore crushing , bed sorting , wet ic sorting , and so on , potassium feldspar powders with purities up to
75 % to 95 % are prepared first. And then , with
