Long ago, zinc refining had not become a general practice among the zinc smelters in the United States. Such refining as had been carried on was confined chiefly to remelting very high-leaded zinc, such as third-draw metal from the retort furnaces, and slab dross, and hard spelter from galvanizing pots. In this remelting operation, the lead and ...

Polymetallic underground mine located in the Ica region, with the highest production capacity in Peru and among the 20 largest zinc mines in the world. Its operations started in 2007. Moreover, it produced approximately 102,300 tons of zinc, 29,100 tons of copper, 12,800 tons of lead, 3,813,700 ounces of silver and 4,800 ounces of gold in 2021.
Lead was the first metal mined in Australia at Glen Osmond in South Australia in 1841, after the wheel of a cart being pulled up a rough track accidentally exposed some lead-zinc ore. In 1876, lead-silver ore was discovered and mined at Thackaringa, near Broken Hill in New South Wales, but the mines closed in 1877.
Over 20 ore zones are mineable, each up to 1.4km long by 800m deep and from 4m to 48m wide. As of mid-2005, Xstrata reported that the underground Isa lead mine had proven reserves of 0.4Mt grading 5.9% zinc, 4.7% lead and 140g/t silver, and measured resources of 1Mt at approximately 7.3% Zn, 6.3% Pb and 180g/t Ag.

mining was practiced and a zinc ore approximating 25 per cent zinc and 11 per cent lead, and a lead ore containing 14 per cent lead and 12 per cent zinc. were shipped to T rail. One was treated in the zinc plant and the other smelted in lead blast furnaces, which also handled the lead-bearing residues of the zinc plant.
Zinc and lead concentrates from various mines were blended and sintered (partly melted) to combine the fine particles into lumps and remove some sulphur as sulphur dioxide. The sintered product was mixed with coke and smelted in a blast furnace to produce zinc vapour (gas), which was condensed by cooling with a spray of molten lead to form ...
