Bioleaching definition chemistry
WebBioleaching is a promising and sustainable technology that is ecofriendly, has a low cost, has low energy consumption, and is simple. At present, bioleaching is not limited to high-grade sulfide minerals; instead, it is widely used in metal recovery from solid waste, such as E-waste, sludge, sediment, batteries, catalysts and low-grade ore. http://www.gcsescience.com/ex23.htm
