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.

2014626Historically smelting and roasting of ores have been used to capture the gold from difficult to treat ores. Just like those old time miners we dont want to throw any of the silver or gold away as it can be valuable. Treating high sulfide ore is a difficult proposition and in the article below Ill take a look at all of the best known

2015216Roasting temperature was the key factor considered during sulfation roasting. Complex copper sulfides decomposed sufficiently and less copper sulfate decomposed were the key step to achieve high copper extraction. When the roasting temperature is no higher than 650C there would be mainly metal sulfates and sulfur dioxide formed.
