ABSTRACT

Nowadays, the problem of fine micro-and nano-scale «invisible» gold, remains urgent,
with the substantial loss of metal during enrichment of sulphide ores. Mineralogical
studies show that the vast majority of native gold in sulphides is in the form of fine, dust
and thin particles, with a subordinate amount is very small and petty.
According to the confirmed reserves of gold, Kazakhstan is among the top ten countries
of the world. The considered balance stock of deposits is 196 (126 autochthonous, 47
complex, 23 alluvial). The share of gold reserves in the complex of gold deposits is
35,1%, in the alluvial - 0.5%.
