Fluorite-containing ore flotation method
Fluorite- containing ore flotation involves pre-treating the mineral in water in an alkaline medium followed by slurrying with an oxyhydrogen collector and sorting it into a valuable fluorite product. In order to increase the recovery of fluorite concentrate, the collector used is a by-product of the production of detergents. This by-product is obtained by purifying synthetic fatty acids of C 17 to C 21 products, and its composition is (%): unsaponifiable matter 4.6 to 7.0, dihaloic acid 15 to 19, isocarbonic acid 40 to 43, and the rest is normal. Structure of the acid.
