Innovations in Copper: Mining & Extraction: Producing

Three of the processes introduced above have made great strides in solving these problems for the extraction of copper from chalcopyrite: The GEOCOAT™ Process A heap leaching process that is capable of bioleaching copper concentrates. It does this by coating the concentrate slurry onto a support rock, or substrate material, and stacking this coated material in a bioxidation heap.

Copper leaching from chalcopyrite concentrates SpringerLink

Abstract. Chalcopyrite (CuFeS 2) is one of the most abundant copperbearing minerals, which accounts for approximately 70 percent of the world''s known copper reserves.For more than 30 years, a significant number of processes have been developed to leach copper from chalcopyrite concentrates.

The Mining Process. The Mining Process. 1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.
