Bioleaching - GCSE Chemistry Definition

Reviewed by: Philippa Platt

Last updated

Bioleaching is a process used in mining and extraction where microorganisms, such as bacteria and fungi, are used to extract metals from ores. This environmentally friendly technique involves the bacteria breaking down the mineral ores into soluble substances, allowing metals like copper, zinc, and gold to be extracted efficiently.

It's particularly valuable for processing low-grade ores that would be uneconomical to mine using traditional methods. By employing naturally occurring microorganisms, bioleaching reduces the need for harmful chemical processes and lowers the energy consumption involved in metal extraction, making it an increasingly popular choice for sustainable mining practices.

In the context of the GCSE Chemistry course, bioleaching is an example of using biology to solve chemical and industrial challenges, illustrating the intersection of science disciplines.
