An ore is that mineral in which a particular metal occurs in some significant amount and can be extracted economically. Some common examples of iron ore are hematite and limonite etc. Extraction of iron The extraction of iron is mainly from its oxide, i.e., hematite, and the process of extraction of iron involves the following steps. Concentration

The first step of physical beneficiation is crushing and grinding the iron ore to its liberation size, the maximum size where individual particles of gangue are separated from the iron minerals. A flow sheet of a typical iron ore crushing and grinding circuit is shown in Figure 1.2.2 (based on Ref. [4]).This type of flow sheet is usually followed when the crude ore …
