Copper Mining and Extraction: Sulfide Ores

About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon. These mines have now closed and today the biggest copper mines are in Chile (Escondida mine) and Indonesia (Grasberg mine). These produce many millions of tonnes of copper ore per year. The main ores of copper are sulfides and ...

Extracting metals from rocks- Learn Chemistry

Class practical. Malachite is a copper ore consisting mainly of basic copper(II) carbonate, CuCO 3.Cu(OH) 2.This experiment involves producing copper from copper(II) carbonate. The copper carbonate is first heated to produce copper(II) oxide, which is then reduced to the metal using carbon as a reducing agent.

From Ore to Finished Product - copper

Copper - From Beginning to End. 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.
