Combined geotechnological schemes for the development of gold-bearing technogenic mineral formations

The article deals with topical issues of involvement in the processing of technogenic (technogenically transformed) gold-bearing mineral formations containing difficult-to-recover forms of gold. Based on the analysis of the features of the formation such mineral formations and the forms of residual gold in them, their types are identified according to the signs of the places of formation and the degree of material-structural transformation. Technogenic mineral formations formed at the site of primary extraction with insignificant material and structural transformation can mainly be worked out by traditional physical and technical geotechnologies, and transformed to an average degree — using non-standard combinations of methods of extraction of mineral mass, recycling and physico-chemical geotechnologies. For gold-bearing technogenic mineral formations located on specially designated areas with both medium and significant changes in material and structural characteristics, the option of their development using a combination of such unconventional physico-chemical geotechnologies as heap, borehole, cuvette leaching is more preferable. Combined geotechnological schemes of heap-borehole and cuvette-borehole leaching with pre-oxidation and with preliminary mechanochemical activation have been developed to develop reserves of gold-bearing tailings of ore enrichment with the most difficult to recover chemically related dispersed and encapsulated forms of gold finding. The effectiveness of these schemes is confirmed by the results of model experiments on samples of tailings of the enrichment of the Baleyskaya concentrating plant ZIF-1, the kek storages of the Pokrovsky and Darasunsky mines.

Keywords: technogenic gold-bearing mineral formations, encapsulated and chemically bound gold, physico-chemical geotechnologies, combined geotechnological development schemes, heap-well leaching, cuvette-well leaching, preliminary mechanochemical activation.
