Integrated estimate of processing flowsheets for silver-bearing primary ore at Rubin deposit

As a result of the accomplished research including the integrated estimate of processing flowsheets for silver-bearing primary ore at Rubin deposit, the mixed-type gravitational separation-and-flotation flowsheet is validated for primary ore, which allows copper recovery of 91–93% and silver recovery of 86–90%. It is advised to use two methods of thermal treatment with further cyanidation of ore: flotation of prime sulfide concentrate with subsequent calcination in oxygen medium; thermal treatment of milled ore with subsequent cyanidation. With a view to determining the oxidized ore processing performance, the full-scale tests were carried out at Rubin gold recovery plant using adsorption at coal, including: two-stage ore milling and classification in cyclones; milled ore thickening; oxidized ore leaching in cyanide solutions (preliminary cyanidation, adsorption from leach solution in activated coal), desorption–electrolysis of silver from pregnant coal, melting of cathode deposit with production of silver bullion.

Keywords: silver-bearing primary ore, autoclave leaching, processing flowsheets, flotation concentrates, cakes, pulp, concentrate, amalgamation.
