Design of Copper Hydrometallurgy Plants for High Grade

Developments are primarily related to leaching of high grade chalcocite pyrite ores and leaching of chalcopyrite concentrates Leaching of chalcopyrite is complicated by passivation of chalcopyrite under mild conditions Most chalcopyrite leaching technologies try to overcome this passivation by one or more techniques This is the critical

Copper extraction

Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copper in concentrate (usually 2729% copper); the remainder of the concentrate is iron and sulfur in the chalcopyrite, and unwanted impurities such as silicate gangue minerals or other sulfide minerals, typically minor amounts of pyrite, sphalerite or galena. Chalcocite concentrates typically grade between 37% and 40% copper in concentrate

The copper concentrate collected in the roughing stage is then reground and passed through a cleaning flotation circuit where conditions are adjusted to promote copper mineral flotation and further suppress pyrite flotation. Post copper recovery, the conditions of flotation are altered in subsequent stages to promote the cobalt/pyrite recovery.

Limits of the CIL circuit in coppergold plants

The leaching of flotation tailings in coppergold plants (e.g., Telfer) is difficult. The occlusion and fine grain size of gold attribute to the low leach recovery. Fine grinding of the pyrite concentrate increases gold recovery from leach. Fine grinding increases released copper ions and cyanide consumption.
