steel ("blanks"). Similar to the sulphide ore refining process, an electrical charge is applied to the liquid, causing the copper to attach to the sheets. Over approximately 10 days, the starter sheets fatten to a width of 2.5 centimetres, forming 99.9 percent copper cathodes. This process is known as "electro winning".

Everything about Gold Processing, Smelting, Refining ...

The smelting process is about extracting the precious metal from its ore. The process yields about 90% of pure gold. However, this percentage of gold is not acceptable in the industry, as it comes with other minerals, such as copper, silver, iron, or aluminum. Smelting comes as the most crucial step of the entire gold mining.

Copper Purification Process - Electrolytic Copper Refining ...

Electrolytic refining (electrorefining) is a process used to make impure copper pure. Unlike aluminum, copper metal is fairly easy to obtain chemically from its ores. By electrolysis, it can be refined and made very pure—up to 99.999%. The electrorefining is at the heart of not only copper purification, but the production of sodium hydroxide ...

MANAGERIAL REVIEW Examining the copper value chain

As the copper content of the ore has only 0.3-1.0 % copper, it is enriched by flotation to a copper concentrate with about 25-35 % copper to avoid processing of a high amount of gangue material. So copper concentrate is the first traded product with a value. There are mining companies with their own smelting and refining
