Experimental research on the formation of mineral-rich areas in residue gold placer deposits

Abstract

Underestimation of the reserves of raw material base of gold mining (namely residue dump complexes) leads to negative social and economic consequences in the regions engaged in placer gold mining. Nonetheless, their efficient development is possible only through the use of new rational technologies of preparation and deep processing of rock mass for subsequent extraction of valuable minerals. In order to create such a technology, large-scale research was made on the nature and degree of the influence that the basic factors of the technology have on the process of migration and concentration of gold particles in a residue rock mass.
