Dec 01, 2014 the froth flotation method has an ideal grain size requirement of 30050 m (smolders et al., 2003). the gravitational settling method, which relies on the density differential between the heavier sulfide and lighter silicate fractions, utilizes a significantly larger grain size of around 1 mm. thus, the tailings grains from the froth .

Flotation froth flotation is an important concentration process. this process can be used to separate any two different particles and operated by the surface chemistry of the particles. in flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp.
