potash feldspar
5.This paper introduces especially geologic features of occurred feldspar druses in granite pegmatite veins of rock crystal and of rare metal minerals, and discribes 6 kinds of feldspar druse. They are pink potash feldspar druse, white potash feldspar druse, white petal like albite druse, white stair like albite druse ,White sheaf like albite druse and transparent plate lile albite druse.
7.The process of separating impregnated iron from potash feldspar has been studied in alkaline solution by JC-COP activator and enhanced leaching agent after reelection and magnetic separation, as a result, the content of Fe2O3 in potash feldspar product decreases from 4.05% to 0.1%~0.2%, and its color becomes white from pink, its quality is high, and the economic benefi t will be improved.
