配制方法：	This material is a gravity concentrate containing calcium fluoride with calcite and silica as the principal gangue constituents. It contains 77% calcium fluoride, 9.5% calcium carbonate, and 12.0% silica. It is ground to 78% minus-200 mesh with 3.5 lb per ton sodium carbonate and 0.20 lb per ton quebracho. It was conditioned for 15 min at 98-102F with 1.0 lb per ton Pamak 4, and the rougher float taken off. This is cleaned four times using 0.075 lb Pamak 4 in each cleaner. Also, 0.3 lb per ton sodium silicate and 0.20 lb per ton quebracho are used in each cleaning step. A final concentrate of 98% CaF2 is obtained.
