Froth flotation is mainly operated under two common techniques : 1. Direct floatation technique – In this method, the mineral sticks to the air bubble and the remaining gangue settles down at the bottom. 2. Reverse floatation technique – In this method, the gangue sticks to the air bubble and ore particles settle down in the bottom.

Gravity separation has been applied to process chrome slag by steel researchers in India. Heavy media separation (Choudhury et al., 1996) and crushing and jigging (Khan et al., 2001) are the principal techniques used. The slag is subjected to 2-stage crushing to reduce the size to −10 mm and then screened into −10 +1 mm and −1 mm fractions.

The flotation method is a relatively common method for purifying minerals. Since the graphite surface is not easily wetted by water, it has good floatability and is easily separated from impurity minerals. The flotation of graphite ore is generally carried out by positive flotation followed by reverse flotation of the flotation concentrate.
