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.

Malachite is a copper carbonate hydroxide mineral, with the formula Cu 2 CO 3 2This opaque, green banded mineral crystallizes in the monoclinic crystal system, and most often forms botryoidal, fibrous, or stalagmitic masses, in fractures and spaces, deep underground, where the water table and hydrothermal fluids provide the means for chemical precipitation.

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
