As with most copper ores, the malachite does not contain pure copper (native copper), and will contain other minerals besides the malachite. Malachite, one of several minerals mined to obtain copper, is mined primarily in Arizona, the leading copper-producing state.
Copper, uranium, vanadium and other metals are produced by solvent extraction. The figure below is a simplified schematic of a typical copper solvent extraction process. Oxide copper ore, low-grade copper sulfide overburden, and other copper-containing materials are stacked into a heap.
Copper can be extracted from its ore by heating it with carbon. Impure copper is purified by electrolysis in which the anode is impure copper, the cathode is pure copper and the electrolyte is copper sulphate solution.

Extracting copper from its ores The method used to extract copper from its ores depends on the nature of the ore. Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, carbonate or sulphate ores. Getting copper from chalcopyrite, CuFeS2 Chalcopyrite (also known as copper pyrites) and similar sulphide
Some copper ores can be converted into copper(II) sulphate solution by leaving the crushed ore in contact with dilute sulphuric acid for a long time. Copper can then be extracted from the copper(II) sulphate solution.

As the acid trickles through the ore, it combines with the copper, producing a weak copper sulfate solution. The so-called 'pregnant' leach solution (or pregnant liquor) is then processed using a hydrometallurgical process known as solvent extraction and electro-winning (or SX-EW).
The sulphate ions bind with copper(II) ions. Heat is applied to hasten the reaction. Extraction of Copper from its Ore Electrolysis of the New Solution Copper (II) ions deposited as copper serves as the cathode.

PREPARATION OF THE COPPER ORE. This study is limited in general to percolation leaching as it is the most widely used method to give proper contact of solvent with the ore to effect extraction of the copper. One of the important factors in percolation leaching is the size reduction necessary for copper recovery within reasonable time limits.

Bioleaching is the extraction of a metal from sulfide ores or concentrates using materials found native to the environment; namely, water, air and microorganisms. In other words, bioleaching is the commercialization of the ability of certain bacteria and archaea, found in nature, to catalyze the oxidation of sulfide minerals.
A process for the extraction of copper a sulphide copper ore or concentrate comprises subjecting the ore or concentrate to pressure oxidation in the presence of oxygen and an acidic chloride solution to obtain a resulting pressure oxidation filtrate and an insoluble basic copper sulphate salt.
Three different stages are involved when extracting copper from non-sulphide ores. 1. Over a very long time and on a vast scale, the reaction of the ore with a dilute acid (such as dilute sulphuric acid) produces an extremely dilute copper sulphate by solvent extraction.
These copper oxide ores are usually leached using sulfuric acid to liberate the copper minerals into a solution of sulfuric acid laden with copper sulfate solution. The copper sulfate solution (called the pregnant leach solution) is then stripped of copper via a solvent extraction and electrowinning (SX-EW) process.
A typical ore contains only 0.5% to 2.0% copper. It is a measure of the value of copper that it is worth extracting it from such small concentrations. The ore is a mixture of minerals and rock (called gangue).

The techniques for extraction of copper from oxidized ores are quite different from those employed for the sulfide ores. The oxidized ores, consisting of the silicates, carbonates and sulfates, are treated by several methods, all involving some form of leaching of the crushed ore with sulfuric acid to produce impure solutions of copper sulfate.

Separation of the bulk concentrate copper and nickel minerals is generally accomplished by flotation of the copper from pentlandite and nickel-bearing iron sulphides which report to the flotation tails.

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.

Open pit: 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers. The ore is treated with dilute sulfuric acid. This trickles slowly through the ore dissolving copper to form copper sulfate. The copper is recovered by electrolytic refining.
Extracting copper from its ores. The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite (\(CuFeS_2\)) are converted to copper by a different method from silicate, carbonate or sulfate ores.
