smelter were adapted to porphyry copper ores. With the exception of leaching-solvent extrac-tion-electrowinning, the basic methods of cop-per production have remained unchanged for 65 years. Moreover, six of the mines opened be-tween 1900 and 1920 are still among the major copper producers in the United States today

Flotation: The process following desliming where the slurry is mixed with various chemicals to assist in separation of additional KCl. Air Injection: The treated slurry is placed in a series of cells and air is circulated through the slurry; particles of KCl attach to rising air bubbles to form a KCl-rich froth on top and is subsequently skimmed off as concentrate

FLOTATION OF COPPER-NICKEL SULFIDE ORES. United States Patent 3667690. Abstract: Flotation of sulphide minerals from their ores is achieved by a process in which two or more conditioning steps are carried out prior to a froth flotation step. The first step comprises conditioning a pulp of the ore in the presence of at least one alkaline agent

May 19, 2020 The dry process is a simple and economical process. After the mined raw ore is crushed to 25.4mm by a hammer crusher, it is fed into a cage crusher to reduce the particle size to 6.35mm. The hot air in the cage crusher reduces the moisture of the kaolin from 20% About 10%. The crushed ore is further refined by a blown Raymond mill equipped with a centrifugal separator and cyclone dust collector. This process
