steps in physical beneficiation of bauxite ore

beneficiation process of bauxite ore
2021-7-17 · Bauxite is mainly used to extract aluminum. About 85% of bauxite can be refined into alumina and then smelted into aluminum, 8% for chemical alumina, and 7% for refractory materials, proppants, and cement. Ore washing is the simplest and most effective method to improve the bauxite aluminum-silicon ratio by about 2 times.

Physical Beneficiation - an overview | ScienceDirect Topics
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 contains below 30% iron.
