Pyrite - Wikipedia

The mineral pyrite (/ ˈ p aɪ r aɪ t /), 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 form of 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.The color has also led to the ...

Pyrite Tailings Recovery by Flotation

The classifier overflow then is pumped to the final flotation cleaner cells. Since the final cleaning of pyrite may be carried out at a pH of from 6.5 to 7.0, lime may be added to the regrind circuit to neutralize the excess acid, thus avoiding the expense of having acid-proof equipment in this part of the flowsheet.

The settled solids are usually conveyed away by some discharge system, while the overflow is collected in launders and pumped away. The classifier designs differ mainly in the mode of removing the underflow and the overflow slurries. Immersed spiral or rakes are generally used for underflow slurries and an open launder carries the overflow.
