zinc processing, the extraction of zinc from its ores and the preparation of zinc metal or chemical compounds for use in various products.. Zinc (Zn) is a metallic element of hexagonal close-packed (hcp) crystal structure and a density of 7.13 grams per cubic centimetre. It has only moderate hardness and can be made ductile and easily worked at temperatures slightly above the ambient.
The zinc processing plant was commissioned, within the budget of US$5 million, midway through the financial year, but due to the lower zinc price, the facility was converted to a cobalt leaching facility to add better value to Sable. This has further improved the recoveries of cobalt. The zinc tailings dumps remain to be processed at a later stage.
