Technology of processing of recycled dusts from roasting and reduction shops of Nickel Plant in pyrometallyrgical production of Nadezhda Metallurgical Plant developed by specialist of Transpolar Division of JSC “MMC Norilsk Nickel” is offered for lowering of action on nature and dwelling areas of Large Norilsk by pollutant emissions. It is also one of the mesures allowing to rise simultaneously efficiency of the metallurgical complex of Transpolar Division. This technology uses the dust-flow scheme into active drag-link conveyor and then into flash smelter for smelting. Tests of this technology demonstrated possibility of handling of recycled dusts without negative impact on process quality at Nadezhdinsky Metallurgical Plant, therethrough, environmental problem solvings by lowering of dust emission in the atmosphere.

Pollutant emissions, recycled dust, roasting and reduction shop, smelting of concentrates, pyrometallyrgical production, drag-link conveyor, flash smelter.
