process of separating iron from ore

9 - Developments in the physical separation of iron ore
2015.1.1 The ore is mainly composed of magnetite, hematite, martite, and quartz. It is very difficult to produce a high-quality iron ore concentrate by magnetic separation alone for this type of iron ore. The ore is first ground using ball mills down to about 90% -75 μm.

Mineral processing - Wikipedia
Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation. In all of these processes, the most important considerations are the economics of the proce

2022.1.1 Compared with base metal ores, iron ores are low value products and, therefore, large tonnages have to be treated to make the upgrading process economically viable. This makes the flotation process, which is ideally suited for treating large tonnages of low-grade material, by far the best option for most of the ores currently being mined.

Metallurgy is the set of processes by which metals are extracted from their ores and converted to more useful forms. Metallurgy consists of three general steps: (1) mining the ore, (2) separating and concentrating the metal or the metal-containing compound, and (3) reducing the ore to the metal. Additional processes are sometimes required to ...
