Knowledge on possibilities of applying mineral biotechnology to treatment of Slovak sulphide ores

Abstract

The summary of results from research aimed at possibilities to use biotechnological procedures for treatment of Slovak sulphide ores is presented in this study. The object of the research is an extraction of valuable metals, undesirable admixtures and degradation of crystallic lattice of sulphides for subsequent chemical leaching processing of precious metals. Further, the results of experiments on existence of biogenic processes in situ on waste dumps from exploitation containing residual sulphides are presented.
