DOI: 10.1016/j.mineng.2019.02.037
Abstract: Abstract During gold extraction by cyanidation, fine gold particles encapsulated in sulfidic minerals are not readily extracted and carbonaceous matter can absorb aurocyanide complexes from the leaching solution. Therefore, high-sulfur and high-arsenic carbonaceous refractory gold… read more here.

DOI: 10.1134/s1028334x19010082
Abstract: The mechanisms of paleodeformations during the time of fluid inflow into the accumulation area of gold ore concentrations were studied for two deposits. It was found that the mechanisms corresponded to seismic mechanisms of the… read more here.
