Mineral Processing. If the mineralogy of the ore shows that you can separate discrete particles of the mineral you want from the gangue components of the ore, then it is possible to physically concentrate the valuable mineral and reject the rest. The easiest method for achieving this is by gravity separation.

Zinc concentrate, which contains approximately 55% zinc, is roasted at a temperature approximately 800°C (1472°F). The methods used to roast the concentrate have an intention to reduce the sulfur content by oxidation to below 1%, so that the zinc oxide product can be reduced by carbon in a retort furnace or blast furnace to zinc metal.
