CN1151894C - Process for extracting potassium feldspar

The present invention discloses a process for extracting potassium feldspar mineral materials. Potassium feldspar minerals (phenocryst) in weathered granites are selected as raw materials; the crystal surface of the minerals are purified through friction and washing; impurities are removed by sieving; after ground, the minerals are separated by a low-intensity magnetic separation method
