Innovations: How Hydrometallurgy and the SX/EW Process Made
The SX/EW Process. The SX/EW Process is a hydrometallurgical process since it operates at ambient temperatures and the copper is in either an aqueous environment or an organic environment during its processing until it is reduced to the metal. Because of its dependence on sulfuric acid, the SX/EW Process is at present not a substitute for, but ...

Copper Ore Processing Methods
The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated.

Energy needed to produce aluminum
After alumina is extracted from bauxite ore, further processing called 'smelting' is necessary to convert it into aluminum. In this process, alumina is dissolved in a solution and a strong electric current is applied. This process has generally remained unchanged since its invention in 1886. Because smelting requires significant amounts of ...

Copper Production: How Is Copper Made?
Manufacturing Process of Copper. Copper processing is a complex process that involves many steps as the manufacturer processes the ore from its raw, mined state into a purified form for use in many industries. Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0% copper.

Water and Energy Use in Mineral Processing: A Case Study in Copper
Energy use is quite relevant to copper production. Energy consumption has important implications because the process itself requires the combustion of fuels and increasing power requirements that cause greenhouse gas emissions at the thermal power stations that supply electricity to the copper plants (Alvarado et al., 2002).
