Comminution and classification technologies of iron ore. Aleksandar Jankovic, in Iron Ore (Second Edition), 2022. 8.3.3.1 Hydrocyclone separators. The hydrocyclone, also referred to as cyclone, is a classifying device that utilizes centrifugal force to accelerate the settling rate of slurry particles and separate particles according to size ...

Minerals are subjected to ore processing to turn them into usable and saleable raw materials. First of all, the ore is reduced to the smallest size with the crushing-grinding process, and after using water and chemical additives, according to the characteristics of the ore, useful minerals are taken, and unwanted minerals are stored in …

Smelting reduction processes avoid this energy use because they make iron directly from iron ore and coal, omitting the need for coke ovens and sinter plants. The cyclone converter furnace consists of a cyclone for pre-reduction of the iron ore; the cyclone is mounted on a converter-type vessel in which the iron ore is then reduced to …
