When lime and ferrous sulphate are added to ,water,, the ferrous hydroxide is formed in the form of flocs. FeSO 4 .7H 2 O + Ca (OH) 2 → Fe (OH) 2 + CaSO 4 + 7H 2 O. 4Fe (OH) 2 + O 2 + 2H 2 O → 4Fe (OH) 3. Ferric hydroxide Fe (OH) 3 is a floe which settles down and removes all the colloidal impurities in ,water,.

This results in saturating the pressurized effluent ,water, with air. The air-saturated ,water, stream is recycled to the front of the float tank and flows through a pressure reduction valve just as it enters the front of the float tank, which results in the air being released in the form of tiny bubbles.

In brief, mine ,waste, covers can decrease oxygen and ,water, penetration, and thus ,reduce, the oxidation of sulfide minerals and/or the transport of hazardous compounds. Inorganic covers can be combined with sludges to improve sealing properties and soil physical conditions and to promote vegetation cover, which is essential to prevent erosion and to improve the aesthetic appearance of the area [31].
