Copper Ore Refining Process

Location Factors: Zinc, Lead, Copper Refining & Acid

Overall, Indian copper ore is average quality, hence mining/refining is a costly because copper yield is low. Lead and Zinc. Dig the ore=>concentrate=> refining. it runs on the principle that certain minerals have an affinity for certain oils. Hence the ore is mixed with water, oil and chemicals.

Environmental Guidelines for Copper Smelting

process the ore is leached with ammonia or sulfuric acid to extract the copper. These processes can operate at atmospheric pressure or as pressure leach circuits. Copper is recovered from solution by electrowinning – a process similar to electrolytic refining. The process is most commonly used for leaching low grade deposits in situ or as heaps.

Copper Mining and Extraction Sulfide Ores

Ores near the surface can be quarried after removal of the surface layers. The ore is treated with dilute sulfuric acid. This trickles slowly through the ore dissolving copper to form copper sulfate. The copper is recovered by electrolytic refining. Advantages of this process are: See for further information on the leaching process.

Cobalt extraction - Wikipedia

Recovery from copper-cobalt sulfide concentrates. The ores are treated by a sulfatizing roast in a fluidized bed furnace to convert copper and cobalt sulfides into soluble sulfates and iron into insoluble hematite.The calcine is subsequently leached with sulfuric acid from the spent copper recovery electrolyte.Oxide concentrates are introduced at this leaching step to maintain the acid balance ...

mining - Copper Ore

Traditional mining – Ore is mined from the ground in an open pit (90% is mined this way) or undergrounds mines. Leaching – ore is treated with diluted sulphuric acid, that trickles through the ore. This then dissolves the copper to form copper sulphate. The copper is later recovered through electrolytic refining.

Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

Copper processing - Ores | Britannica

Extraction and refining. The extraction of copper from ore is normally carried out in three major steps. 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.
