Flotation of Pyrite - Metallurgist & Mineral Processing ...

Since no iron compounds, other than pyrite and chalcopyrite, were present, the pyrite was calculated from the ratio FeS2 : Fe = 2.143 : 1, after deducting the iron held by the chalcopyrite, as in sample mixture No. 1; the pyritic content in sample mixture No. 2 was found to be 23.60 per cent. The tests were run precisely as in the case of the Mountain Copper sample.

1 Froth Flotation – Fundamental Principles

Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry.

Pyrite - Wikipedia

The mineral pyrite, or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula FeS 2 (iron(II) disulfide). Pyrite is considered the most common of the sulfide minerals . Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold .

Froth flotation - Wikipedia

Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity. Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.
