Detailed explanation-1: -What is bioleaching or biomining? Bioleaching (or biomining) is a process in mining and biohydrometallurgy (natural processes of interactions between microbes and minerals) that extracts valuable metals from a low-grade ore with the help of microorganisms such as bacteria or archaea.

Detailed explanation-2: -Microbial ore leaching (bioleaching) is the process of extracting metals from ores with the use of microorganisms. This method is used to recover many different precious metals like copper, lead, zinc, gold, silver, and nickel. Microorganisms are used because they can: lower the production costs.

Detailed explanation-3: -Bioleaching can be used to extract copper metal. It does not need high temperatures, but it produces toxic substances, including sulfuric acid, which damage the environment.

Detailed explanation-4: -2.1 Thiobacillus. The bacteria most active in bioleaching belong to the genus Thiobacillus. These are Gram-negative, non-spore forming rods which grow under aerobic conditions.

Detailed explanation-5: -Bioleaching is a conversion of an insoluble valuable metal into a soluble form by means of microorganisms. In biooxidation, on the other hand, gold is predominantly unlocked from refractory ores in large-scale stirred-tank biooxidation arrangements for further processing steps.
