This occurs as the ore fluid rapidly enters the fracture space by the action of the pressure gradient due to the rapid decrease in pressure, in which a large number of volatile components such as H 2 O and HCL escape, causing the pH to rise and the metal concentration to increase. Then, the sulfur in the gas phase dissolves into the liquid ...Web

The procedure of ore concentration is a critical stage in obtaining pure metal from ore. Separating ore from gangue particles is required for metal extraction. Ore discovered in the soil contains several impurities such as sand, grit, pebbles, and so on, which are collectively referred to as "Gangue.". The initial step in metal extraction ...Web

Heating the powdered ore with a concentrated solution of NaOH at 473–523 K and 35–36 bar pressure is used to concentrate it. Digestion is the term for this procedure. Al 2 O 3 is extracted as sodium aluminate in this manner. The impurity SiO 2 dissolves as well, resulting in sodium silicate.Web

In simple words, the concentration of ore is the method of separating ore from the gangue, as the gangue or matrix particles are the valueless substances that are of no use. The ore can be concentrated or separated by both physical and chemical means. The ore obtained after the completion of the ore concentration is called concentrate.Web
