We recommend that you begin by screening the to separate fine particles below the crusher’s CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.read more
To efficiently process iron ore for high quality steel production, frequent ore grade monitoring, during all steps of downstream processing, is mandatory. Independent from the ironmaking method, the optimal use of fuels and energy during sintering, pelletizing and direct reduction of iron ore DRI needs to be applied to stay competitive and produce environmentally friendly.read more
Haematite and magnetite are the most commonly found iron ore minerals. The allows the iron ore to be heated with carbon. The carbon combines with the oxygen and carries it away, leaving behind iron. Blast furnaces are so hot which is why they melt the iron, and drain it off to be poured into moulds to form bars, called ingots.read more
