The load out of the concentrate will use an innovated conveyor loading process whereby lead and zinc concentrate will be loaded directly into containers on discharge from the filters. The concentrator plant includes single stage crushing, with conveyors that deliver the ore to a coarse ore bin.
Our processing plant at McArthur River Mine extracts the zinc and lead from the ore in preparation for export to smelters. A conveyor transports raw material to the processing plant. Crushing and grinding. The impure zinc lead ore transported from the mine is ground into a fine dust.
Zinc smelting is the process of converting zinc concentrates into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point. At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific measures are taken to prevent it.
