Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm.

US3936372A Method for beneficiation of magnesite ore

A method for beneficiation of magnesite ore wherein the ore is subjected to calcination to decrease the bulk density of the magnesite relative to the gangue. Accordingly, after such calcination, conventional gravimetric separations can be conducted with greatly increased efficiency. When the calcination is conducted in a reducing atmosphere, initially non-magnetic gangue material is converted

Isostearic acid, a liquid isomer of stearic acid, is used as an agent in a froth flotation process to concentrate the iron oxide in iron ores. By use of this flotation agent, the iron oxide in the ground ore is directly floated away from the remainder of the ore. The process enables a high amount of iron oxide to be concentrated from low grade ores.
