iron ore processing methods

Iron Smelting | Essential Humanities

The iron is then drained from the bottom of the furnace into a mould and allowed to harden. 16 The blast furnace remains the principal method of smelting iron to this day. 14 There is a tradeoff for this speed, however: melting the iron causes it to take on a very high (2-4%) carbon content, thus resulting in brittle cast iron .

Iron ore mineral processing method - sinoninetech.com

At present, there is no reasonable way to use ferric silicate. Therefore, iron silicate in ore does not emphasize recovery. Although iron silicate can be recovered by mineral processing method, because iron grade in iron bearing silicate minerals is low, it will reduce the total concentrate grade greatly, which is unreasonable in economy.
