The bio-beneficiation process occurs in mild conditions using bio-reagents derived from microbes and offers a reduction of chemicals used in processing. Bio-beneficiation of iron ore potentially offers a relatively energy-efficient, cost-effective, and environmentally friendly method of maximum iron ore recovery.

Other ore beneficiation techniques include flotation, however there is significant loss of good grade phosphate ore when the ground high-silicate pebbles go through the desliming process, which separates the rocks by size. Furthermore, it is important to significantly reduce high-silica content ores before the grounding step.

Iron ore pellets are largely characterized by inherent physical and chemical properties of the ore. Alumina and silica play important roles in determining the productivity of a Blast Furnace. On average, one percent increase in iron content improves productivity by 2% and reduces coke consumption by 1%. Therefore higher iron ore feed content to …

Phosphate ore is an important raw material for manufacturing fertilizers and phosphorous chemical products. While most of the phosphate resources cannot be directly treated as feed stock due to the low grade of P2O5 and high content of impurities. In order to obtain a qualified phosphate concentrate, the beneficiation of the low-grade …

Active silica has a positive effect as it reduces corrosion by reacting with fluoride and influences phosphogypsum crystallization in phosphoric acid production [118]. If the rock is rich in silica, colloidal silica formed and blinds the filter cloth, thus hampering the filtration efficiency similar to fine quartz crystals [33]. However, in ...
