    In most flotation plants, sulfur and silver on gold grains (in all likelihood in the form of silver sulfide) promoted gold flotation. Copper must be assisting gold flotation as deciphered from the superior floatability of auricupride [Cu 3 Au] and tetra auricupride [AuCu] relative to native gold.
