Chalcopyrite (Cu) Sphalerite (Zn) Separation by Flotation
Zinc 12.45%. Gold 0.01 oz/ton. Iron 32.84%. Silver 1.50 oz/ton. Insoluble 8.50%. In order to meet smelter requirements it is desired to produce at least a 20% copper concentrate with not over 8% zinc. The copper is present principally as chalcopyrite in extremely close association with both the sphalerite and pyrite.
