How is copper extracted from malachite ore?

A reduction reaction could be used. All we need to do is add malachite to a hot fire: http://www.ancient-arts.org/pent... When heated, the malachite decomposes to copper oxide. However, in the presence of burning carbon (hot coals), the carbon steals the oxygen leaving copper metal behind. This video shows the process:. read more

The ore field was sprayed with sulfuric acid, leaching the copper, resulting in copper sulfate rich solution. The leachant is collected at the bottom of the ore field and piped to a tank house where copper was removed from copper rich solution via electrolysis. read more

Chemistry Extracting Copper from Malachite We extracted Copper from Malachite using a displacement reaction. Although electrolysis can also be used. We used 5g of malachite and dissolved it in sulphuric acid; this was to separate the sand and the copper, because the copper dissolves into the solution but the sand remains separate. read more

This experiment involves producing copper from copper ore (malachite). The composition of malachite is mainly copper(II) carbonate CuCO 3. Cu(OH) 2. This experiment involves heating the copper(II) carbonate with carbon. read more
