Roasting or calcination of the ore oxidies some of the sulfur phosphorus and arsenic impurities. Sulfur oxide is volatile and evaporates off or is washed out. Iron is mainly extracted from hematite Fe 2 O 3 and magnetite ores. Natural or direct shipping iron ores contain between 5070 iron and can be fed directly into the blast furnace.

2020327Normally the gold smelting process commences after retorting is carried out so this should naturally be the point when flux gets added. As soon as the charge leaves the retort process the crucible should be preheated.The mixture of already mixed fluxes and ore is then poured into the crucibles which are placed into the furnace.
