Copper Mining and Processing: Resources and Glossary ...

For copper oxide ore, electrowinning is the final stage in the process of hydrometallurgy, in which concentrated copper solution from the heap leaching and solvent extraction processes is used as an electrolyte; an electric current is applied through an inert anode, resulting in the plating of copper onto 99.9% pure copper cathodes.

12.3 Primary Copper Smelting

Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 12.3.2 Process Description2-4 Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper.

Recovery of Copper by Solution Mining Methods

A Brief History of Copper Recovery by Solu-tion Mining Methods As early as the 1670, copper-bearing mine waters at the Rio Tinto mine in Spain were known to chemically precipitate copper onto iron (Arbiter and Fletcher, 1994). This process became known as the “cementation process”, which is apparently derived from the Spanish word

Stage 3: Roasting At this stage of the process, the chemical reactions begin. They convert the copper minerals into copper metal. We can illustrate the types of process using the example of chalcopyrite – CuFeS 2.From the formula, it is clear that iron and sulfur have to be removed in order to produce copper.

Energy efficiency • Energy intensity in copper and gold mining

In the production of copper, sulfidic ores are enriched into concentrates by grinding and flotation, followed by pyrometallurgical processes for the production of pure copper. Oxidic ores are treated with sulfuric acid in a heap leaching process after the grinding stage and are subsequently processed into cathode copper by SX/EW methods.

How Hydrometallurgy and the SX/EW Process Made Copper

In this process copper ore is mined, crushed, ground, concentrated, smelted and refined. The mining, crushing and grinding portions of the processing are extremely energy intensive since the rock must be reduced essentially to talcum powder fineness in order to separate the copper-bearing minerals from it.

Top 10 active copper mines in Canada Mining Energy

Mar 21, 2019  Most companies mine copper as a co-product in conjunction with other metals, such as molybdenum, zinc, nickel or lead, and it is typically found in large sulfide and porphyry deposits. These are some of the top active copper mining operations in Canada: Highland Valley Copper Operations. Location: 17 kilometres west of Logan Lake, B.C.

The Mining Process – Waihi Gold

See more detail on grinding and sizing. 5. Leaching and adsorption A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver.

Chapter 7 Energy Use in the Copper Industry

Grinding and concentration together consume about 45 percent of the energy used in the pro-duction of cathode copper. Assuming an ore grade of 0.55 percent and a recovery rate of87.5 6.4 percent copper in the concentrate, concentrat-ing 1 ton of copper ore requires over 200 billion Btu, or approximately 42 million Btu/ton of cath-

Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW (solvent extraction/electrowinning).
