separation pyrite from tin ore by froth flotation

OPTIMISATION OF GOLD RECOVERY BY SELECTIVE GOLD .

It is usual practice to add sodium cyanide (NaCN) as a depressant of sphalerite and pyrite in the selective flotation of copper zinc and lead copper zinc ore. Low levels of NaCN are enough to depress gold and pyrite flotation. NaCN causes the metal xanthate to become more soluble preventing absorption of the collector.
