Developing new ways to advance copper production
The process is similar to the Hall-Héroult process, which uses electrolysis to produce aluminum, but operates at a higher operating temperature to enable production of liquid copper. Currently, it takes multiple steps to separate out copper, first crushing sulfide minerals, and then floating out the copper-bearing parts.

Copper Mining & Processing: Everything You Need to Know
Copper is usually mined in two ways: open-pit mining and underground mining. Open-pit mining is used for copper deposits closer to the surface. Enormous machines dig up the ground in stair-stepped layers (called "benches") until the copper is extracted using drilling equipment and explosives.

Current Status of Copper-Ore Processing: A Review
IN PROCESSING COPPER ORES In recent times, a low copper content in ores has been observed (ores containing 0.2–0.3% copper are used for processing in Canada and the United States, and ores containing at least 0.4% copper are used in Russia [4]) owing to the exhaustion of rich copper resources. The flowsheet of processing copper ores is

Producing Copper Nature's Way: Bioleaching
The "Gall-Copper Process" was recorded as being used during the Song Dynasty (960-1271AD). Copper was precipitated from solution by dipping iron into the blue vil solution - a process identified as early as 150 BC in China. 6 Therefore, presumably, the recognition of a natural copper leaching process can be identified as early as that date.
