Once it’s removed from the earth, the concentrate is roasted at a temperature of 950 degrees Celsius, causing zinc, sulfur and iron oxidization. After the zinc and iron oxides are reduced to powder form and leached with diluted sulfuric acid, the solution is neutralized and contaminants are removed via filtration. In the foundry, the zinc goes on to take its final form.

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 impure molten zinc metal (98.3% zinc). To remove the small amount of lead and cadmium impurities the liquid zinc was twice boiled to zinc vapour and recondensed to produce high purity zinc metal (up to 99.95%).

Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.
