Copper Ore - an overview | ScienceDirect Topics

This mine has been in operation since 1994 using nonflooded heap leaching to produce 10,000 tons/year of copper from mixture of oxides and sulfides (atacamite and chalcocite). Chuquicamata Low-grade sulfide dump leach was the first in copper hydrometallurgy by the Chilean company of Codelco for a number of years, focusing on bioleaching of low grade 0.3%

Copper Mining and Processing: Everything you Need to Know

The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today’s compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it’s roasted, which helps to convert sulfides to oxides.

In situ leach - Wikipedia

In-situ leaching (ISL), also called in-situ recovery (ISR) or solution mining, is a mining process used to recover minerals such as copper and uranium through boreholes drilled into a deposit, in situ.In situ leach works by artificially dissolving minerals occurring naturally in a solid state. For recovery of material occurring naturally in solution, see: Brine mining.
