Pyrite Flotation Froth Flotation (Sulphide & Oxide

Can you list the factors affects the floatability of pyrite from refractory low grade ore. I used a Wemco lab flotation cell and aimed on analysing factors like collector dosages (PAX), Activator (Copper sulphate),MIBC,pH and others like pulp density and particle size (70 and 150 microns) .However how these factors affect the floatability of the pyrites from low grade refractory ore.
