Abstract

Microorganisms capable of oxidizing sulfide minerals were isolated for the bioleaching experiments. Ore samples from the Allarechensk mining waste dump and low-grade ore samples from the deposit Nud II were studied. The samples have a similar ore mineral composition – pyrrhotite, pentlandite, chalcopyrite, and magnetite. In the study, the solution was recycled to make the process environmentally friendly.
