Abstract
Sewage sludge, waste water treatment plant sludge and many other wastes contains considerable amounts of heavy metals. It is a prime work to remove all the heavy metals before letting it to the natural resources. The main aim of bioleaching is the removal heavy metals which may be toxic and harms the environment. Bioleaching is a promising (could be progressive) technique that utilizes earth sound advancements that are helpful for the digging business and furthermore for ecological detoxification. In bioleaching, the microorganisms produce a chemical compound which includes natural acids, polymers and proteins. This process also has some potential effects on metal retrieval as well as detoxification of waste materials.
