Iron ore processing After the iron ore has been prepared by crushing and grinding during ore extraction, the ore is actually processed. The aim of this is to reduce the undesirable high proportion of admixtures to a desired minimum in order to increase the iron content. This is done by processes such as flotation or magnetic separation.

The annual processing capacity of iron ore reaches 22 million tons, and the wastewater from mineral processing is about 400 thousand m 3 every day. If the dressing wastewater is directly discharged into the nature, it will not only pollute the surrounding environment but also has a great potential safety risk.

Saprolite-type ore characterized by high magnesia and silica contents is treated by pyrometallurgy process. On the other hand, limonite-type ore is subjected to hydrometallurgy process to produce nickel products. Hydrometallurgy process requires that a raw material to meet the demands that Si+Mg contents lower than 10% and Fe content over than 40%.

Iron is most commonly extracted from the iron rock by way of blast furnace at very high temperatures. Iron ores can contain oxide and other impurities. When the ore is heated, it will separate the oxygen from the iron. Additionally, adding some calcium oxide will help remove the impurities, often called slag, from the iron.
