Four Major Flotation Separation Processes to Separate ...

Chalcopyrite is a widely distributed copper-iron sulfide mineral, often containing trace amounts of gold, silver and other minerals, and is the main copper-containing mineral. With the deepening of mining, low grade polymetallic refractory chalcopyrite has become an important source of copper ore. Now, let’s know the common chalcopyrite flotation processes together.

US4256553A - Recovering copper from chalcopyrite ...

A process and system are provided for recovering copper from chalcopyrite concentrate. The chalcopyrite is ground to a mean particle size of about 1.5-5 microns. The ground chalcopyrite is then divided into a first stream and a second stream. The first stream is leached in a leach solution containing at least about 100 gpl sulfuric acid and about 10-30 gpl ferric iron to produce a copper ...

The original chalcopyrite is typically oxidized to chrysocolla, copper wad and copper carbonates. Supergene chalcocite is locally present. Three mineralization domains (oxide, mixed and sulfide) were defined based on the soluble to total copper ratio (ASCu/TCu) collected in the Augusta (2005 to 2012) and Hudbay (2014 and 2015) drilling programs.
