Separation of Iron Particles from Banded Haematite Quartzite (BHQ) Ore
In the separation process, the effects of pH, magnetic intensity and addition of oleate-magnetite are studied to achieve the maximum grade and recovery of iron values. The optimum separation is observed at pH of 7.5, oleate-magnetite concentration of 0.25 ml/g of BHQ ore and a magnetic intensity of around 0.8 Tesla.

Extraction of Metals from Ores – Different Processes Involved
It can only be done when the ore forms froth when compressed air is passed in this medium. 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.
