Key Stage 4

Meaning

Bioleaching is a process of extracting minerals from their ore using bacteria then using electrolysis in solution to extract the metal form the mineral.

About Bioleaching

Bioleaching has several stages:

Waste low grade ores are fed to bacteria where they take in the minerals and through chemical reactions convert them into soluble minerals.
The solution is then filtered.

Electrolysis is then used to extract the metal from the mineral.

Bioleaching is cheaper than smelting but takes much longer to extract the minerals than conventional mining.

Bioleaching is used on the waste low grade ores from mining smelting would be too expensive and not enough mineral extracted.
