Biogeotechnology Application in the Recovery of Metals from the Wastes of Processing Plants

Article Preview

Abstract:

In order to recovery base and precious metals from processing plants tailings of Southern Ural and the Murmansk region, test work on heap biooxidation using these products was carried out. These tests involved the chemical and mineralogical analyses of the samples, the bacteria adaptation for the products tested, heap biooxidation in percolation columns, base metals (copper, nickel, zinc) precipitation and gold cyanidation. The recoveries of base metals to the solution from the products of magnetic separation of the wastes were 75% Ni and 50% Cu. This work is aimed at studying sustainability of magnetic separation products and pyrite tailings biotechnological processing. Also, gold and base metals recovery to the solution and the options of base metals removal from the solutions were studied.
