2020-5-2 Bioleaching involves the use of microorganisms to catalyze the oxidation of iron sulfides to create ferric sulfate and sulfuric acid. Ferric sulfate, which is a powerful oxidizing agent, then oxidizes the copper sulfide minerals and the copper contained is then leached by the sulfuric acid formed.

2021-1-17 Bioleaching. Bioleaching is the . extraction of specific metals from their ores using bacteria. Certain bacteria can break down low-grade ores to produce an acidic solution containing copper ions. The solution is called a leachate and the process is called bioleaching. Iron is more reactive than copper. It can displace copper from the leachate.

2015-6-17 Traditional methods. Copper is usually sourced from copper-rich ores in two main methods; Copper can be smelted in a furnace by heating it with air to produce crude copper metal; for example, chalcocite is an ore of copper (I) sulfide, which reacts with oxygen to extract the copper: Cu 2 S (s) + O 2 (g) → 2Cu (s) + SO 2 (g) Copper ore can also be reacted with sulfuric acid to produce copper

Bioleaching is a technique that makes use of bacteria to extract metals from metal ores. Some strains of bacteria are capable of breaking down ores to form acidic solutions containing metals ions such as copper (II) The solution is called a leachate which contains significant quantities of metal ions. The ions can then be reduced to the solid
