Methods of processing and extraction of copper ore
Magnetic enrichment methods are used in the processing of copper-magnetite ores, for the extraction of monoclinic pyrrhotite from copper-nickel ores, the regeneration of heavy suspensions, and the additional extraction of iron-containing and other weakly magnetic minerals from ores or tailings.

Copper Ore Processing Methods
The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated.

Copper: Mineral information, data and localities.
Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals (such as chalcopyrite or chalcocite) and followed by smelting and electrolytic refining to produce a pure copper cathode. An increasing share of copper is produced from acid leaching ...

Copper Mineral | Uses and Properties
Copper is an excellent conductor of electricity. Most copper mined today is used to conduct electricity - mostly as wiring. It is also an excellent conductor of heat and is used in cooking utensils, heat sinks, and heat exchangers. Large amounts are also used to make alloys such as brass (copper and zinc) and bronze (copper, tin, and zinc).

Copper processing
The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper.

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.

Froth flotation is a process used to concentrate copper sulfide ores. Ground ore is mixed with water and reagents, making copper minerals hydrophobic. Air is pumped into the mixture, creating bubbles that cling to the copper minerals and carry them to the surface. The froth, rich in copper, is skimmed off, leaving behind waste material.

Innovations: Introduction to Copper: Mining & Extraction
The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.

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.
