Copper extraction

Copper extraction

Copper extraction refers to the methods used to obtaining copper from its ores.The conversion of copper consists of a series of chemical, physical, and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

Smelting

Smelting

Smelting is a process of applying heat to ore in order to extract out a base metal.It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.
