Heavy Mineral Processing at Richards Bay Minerals

2009-8-26 · Quebec Iron and Titanium (QIT Fer et Titane) in Sorel, Canada where coarse ilmenite is smelted to produce a high-TiO2 slag and pig iron in similar furnaces. This technology was adapted for RBM to process the fine ilmenite concentrate mined on the north coast of KwaZulu-Natal.5 The process generates very little in the way of waste products.

How iron is made

Iron ore is converted into various types of iron through several processes. The most common process is the use of a blast furnace to produce pig iron which is about 92-94% iron and 3-5% carbon with smaller amounts of other elements.

2018-9-18 · During dry processing, hard massive ore results in generation of coarser fraction known as sized ore having size from 10 to 40 mm and used in blast furnace while soft goethite-rich mineral tends to generate fine fraction known as fine ore having size below 8–10 mm. Dry processing of iron ore is popular for treating hard massive hematitic ores; however, fines generated during processing of goethite-rich mineral cause significant quantity loss of iron values in rejects and make the process ...

The inclination and the rotary motion of the kiln ensure that the raw materials move from the feed end to the discharge end of the kiln and during this movement the actual reduction of iron ore to iron takes place. The material discharged from the kiln is taken to a rotary cooler for cooling and the cooled product is separated from the coal char.
