The frothed ore collects on the oil section whereas the impurities settle down in the water medium. Chemical Separation: One way of concentrating the ore is by chemical separation. For example, the separation of aluminium (Al) from the bauxite ore. This process of separating aluminium from the bauxite ore is also termed Bayer's Process.

Iron is concentrated by the process of calcinations. Once it is concentrated, the water and other volatile impurities such as sulfur and carbonates are removed. This concentrated ore is then mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.

Mar 22, 2022Beneficiation process. Magnetite is the most important iron ore mineral. Cut-off grade is 20%, and the industrial grade is 25%. There are usually 3 magnetite beneficiation methods: (1) Single weak magnetic separation. (2) Weak magnetic separation - reverse flotation. (3) Weak magnetic-strong magnetic-flotation combined process.
