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
