Copper Mining and Processing: Resources and Glossary
2. In copper processing, a copper cathode is the final, 99.99% pure product of the electrolysis process, and is itself the primary raw material input for the production of finished copper products, such as rode, tubes, and wires. cation: A positively-charged ion that is attracted to the cathode (negative terminal) in electrolysis.

12.9: Mining
The total movement of ore and waste constitutes the mining process. Often more waste than ore is mined during the life of a mine, depending on the nature and location of the ore body. Waste removal and placement is a major cost to the mining operator, so a detailed characterization of the waste material forms an essential part of the geological ...

It's a long process which begins with Concentration through calcination roasting. Concentration removes the water and other volatile impurities such as sulphur and carbonates. This concentrated ore is mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.

25.1 Exploration: Finding minerals | Mining of mineral resources
The mining industry is an important industry in South Africa. It involves a number of industries working together. Exploration is followed by excavation, which is followed by crushing and milling to reduce the size of the rocks. This is followed by extraction (removing the valuable minerals from the ore) and finally refining.

The six main steps of iron ore processing
Six steps to process iron ore. 1. Screening. We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency.

The refining process was also introduced in 1890. The four metallurgical processes consisted of calcination, melting, kneading, and refining; a soft-charcoal furnace was used for the calcination (15-20 days) and for deriving crude copper by the oxygen-burning method; and a round-bottomed furnace for melting ores (called "Yamashita blast," 6 hours).
