Using this method represents a budget-friendly approach that also preserves the environment when compared to conventional smelting processes. Bioleaching operations need cautious microbial and environmental supervision to perform efficiently, although their processing pace remains slower.

• Gold: The bioleaching process allows extraction of higher amounts of gold from refractory sulfide ores by breaking down these ores through mineral transformations. The chemical activity of Acidithiobacillus species brings sulfide minerals to oxidation stages, which allows gold to become accessible for cyanidation. This procedure helps decrease the requirement for dangerous chemicals such as cyanide, thus enhancing sustainability. The application of bioleaching technology for gold recovery exceeds in time consumption and demands strict management of biological system parameters.

• Nickel: The process of bioleaching represents a developing method that helps obtain nickel from laterite and sulfide ores. Certain microorganisms as well as fungal species work together to break down nickel-bearing minerals and produce nickel-containing solutions. The technique serves as an effective choice for processing low-grade ores because it provides a better alternative than traditional extraction. The full-scale commercial deployment of nickel bioleaching encounters obstacles for industrial operations.

• Zinc: The extraction of zinc from sphalerite sulfide ores by acidophilic bacteria follows a bioleaching method. Responsible microorganisms perform microbial oxidation to transform zinc sulfide minerals into zinc sulfate which becomes soluble through the process. The bioleaching process offers an eco-friendly substitute over traditional roasting and smelting methods to decrease sulfur dioxide air pollution. The efficiency of bioleaching operations to extract zinc relies on both the characteristics of the ore material and the biological resistance of the bacteria used for processing.
