Bioleaching Of Indiumbearing Sphalerite Under

Minimization the pollution of water, soil and air, caused by conventional mining methods, can be achieved by alternative techniques such as biohydrometallurgy, namely bioleaching. This technique utilizes the activity of iron-oxidizing bacteria to catalyze the dissolution of sulfide minerals, in our case local sphalerite (ZnS) with traces of indium.
