flotation cell machine of gold associated with pyrite Tailings Tailings, also called mine dumps, culm dumps, slimes, tails, refuse, leach residue or slickens, terra cone (terrikon), are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.
The microflotation experiments results indicated that plasma pretreatment can achieve selective flotation of arsenopyrite from pyrite. The XPS analysis results indicated that the oxidation degree of plasmamodification arsenopyrite surface is much higher than that of pyrite.
(1) The flotation of pyrite was depressed strongly by SGX while the floatability of chalcopyrite only slightly reduced at the pH range 710, and the optimal differential flotation chalcopyrite from pyrite was achieved at weakly alkaline pH range, with SBX as collector. (2)

Another portion of sample No. 1 was crushed through rolls to pass a 48mesh Tyler standard screen instead of a 100mesh screenthis material, called sample mixture No. 4, was used in the tests made to determine the effect of size of mineral grains on the flotation of pyrite.
A reagent was given a "+"rating on performance (see Table 1) if a relatively small reagent concentration produced a high degree of pyrite rejection in flotation tests. A ""performance rating was given if a relatively large reagent concentration was needed to produce a high or low degree of pyrite rejection.
The Pyrite Leach Project is expected to recover approximately 35% of the gold and 42% of the silver currently reporting to the tailings and is expected to add production of over 1 million ounces of gold and 45 million ounces of silver over the current life of the mine.
