Ageev, O.A., Medkov, M.A., Ivannikov, S.I., Yudakov, A.A. and Taskin, A.V., (2014) The prospects of obtaining gold from technogenous objects deposit "Nagima", Modern Science: Researches, Ideas, Results, Technologies, Iss. #2(15), PP. 39 - 44. doi: 10.23877/MS.TS.18.008.


technogenic deposits of gold; dispersed gold; assay analysis; neutron-activation analysis; ammonia-thiosulfate leaching


The following specifications of deposit "Nagima" were shown: causes of appearance, peculiarities of structure and formation; distribution and the deportment of gold. The substantial portion of the gold was shown scattered in the crystal lattice of minerals-carriers of individual atoms (dispersed gold), as well as nano-clusters-clusters (powder-nano gold) in technogenous objects.
The forecast assessment of the mineral raw materials quality and the analysis of gold content in various technogenic objects of deposit "Nagima" were conducted, with assistance methods of assay and neutron activation analysis. The advantages of using neutron activation analysis for the analysis of dispersed and nano gold has been shown.
Perspectives of using technogenic objects of deposit "Nagima" as an important source of gold have been shown. It has been established that the application of modern non cyanide methods in hydrometallurgy, particularly ammonium thiosulfate leaching, allows effectively remove thin and fine gold from technogenic objects deposit "Nagima".
