Silver-Containing Concentrate Processing

The goal of the research was to melt the silver-containing concentrate from the Dukatsk deposit (Magadansk region) in a reverberatory furnace. Preparatory research has established that internal collector smelting is an effective way to recover precious metals from the flotation concentrate of the Dukatsk deposit. This method is based on the property of lead and copper in the concentrate in an amount comparable to that of silver, to collect precious metals in a metal or matte phase in the process of segregation smelting. Recovery of silver in a high-grade alloy in one technological operation corresponds to the planned performance (silver recovery into an alloy of 93.0%) in processing flotation concentrates at non-ferrous industry plants.
