Processes - extraction, mining, smelting, refining ...

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

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.

Innovations: Introduction to Copper: Mining Extraction

Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is generally limited to rich ores. El Teniente, in Chile, is the world's largest underground copper mine. Open pit mining

From Ore to Finished Product - Copper

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. Today, copper's uses have expanded to include heating,

by products of copper mining

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively,

Copper production environmental impact

The copper-bearing solution, from the solvent extraction operations, is plated into pure copper cathodes using a process called solution exchange electrowinning (SX-EW). Stainless steel blanks are added to the plating tanks to act as cathodes and copper is plated onto them by electro-chemical deposition. It takes about a week before the cathode is ready to be removed

An Introduction to the Electrolysis Process

Copper refining to an almost pure state done by electrolysis is an excellent example of the process. Blister copper is considered to be a highly pure form of copper - around 99%. However, in today's market, this level of purity is still not enough; as a result, the blister copper is purified further using an electrolysis process known as electrolytic refining. In this process,

Ore processing in the Bronze Age

Tin was not present at Alderley Edge but some arsenious ores such as enargite (copper arsenic sulphide) are present and it has been speculated elsewhere that the addition of these to the smelting process could have led to the manufacture of bronze. It has been found that adding iron ores to copper smelting helps as the iron ore acts as a flux, reducing the temperature required
