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.

Flotation Circuit

1 Introduction. Flotation circuits are commonly used for the concentration of a broad range of minerals; such circuits also used in wastewater treatment (Rubio et al. 2002 ). Froth flotation is based on the differences in the ability of air bubbles to adhere to specific mineral surfaces in a solid/water slurry.

Pyrite Depression in Copper Flotation

The Pyrite Depression in a Copper Only Flotation circuit is simple enough. If your froth flotation system only tries to recover chalcopyrite-copper, you need to bring the plant's pH up to the other side (right side) of the PYRITE curve. The more flotation collector you have on, the higher you will need to increase that pH for effective pyrite ...
