Considered the natural conditions for the fo rmation of gold, given the model of its deposits in the form of a schematic of industrial-genetic classification. Were shown the main types and examples of fields. We have created a model can serve as the scientific basis for prediction and exploration of new industrial facilities to enhance the mineral resource base of mining and processing enterprises of Kazakhstan.

The mineralogical and technological study of gold ores and dressing products demonstrate the persistence of both the ores and products of their dressing, especially Floatation concentrates. The gold loss in the tails of Floatation beneficiation are primarily associated with the smallest size fractions less than 20 microns, which make up to 70\% of the total lost gold in the Floatation tails. It is obvious that increasing the extraction of gold by Floatation is directly linked to the development of the technologica...

Nowadays, the problem of fine micro-and nano-scale В«invisibleВ» 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...
