How Is Zinc Extracted From Its Ore

NFA

Stage 1. The low concentrations of the zinc sulphide mineral in most zinc ores mean that the ore must first be concentrated before extracting the metal. The zinc blende (sphalerite: zinc sulphide)is first crushed to powder and then treated by froth flotation (that process is described in the copper unit.

How is zinc extracted from its ore - Answers

Zinc is extracted from its ore by calcination to remove the sulphur converting zinc to an oxide. The next step is to smelt the particular oxide with carbon where it is combined with oxygen to form a gas. Finally, the deoxidised metal distils in vapour and is then precipitated again into the solid form after extraction.

Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity (electrowinning).
