Phytomining Bioleaching Thailandl

Bioleaching is in general simpler and cheaper to operate and maintain than traditional processes. The bacterial leaching process is very slow compared to other methods. The process is more environmentally friendly than traditional extraction methods. Less profit is made from bioleaching which means it is less appealing to buisness men and women.

    How is bioleaching used to extract copper

    May 02 2020 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.
