The depression of pyrite flotation by cyanide may result from one or more of the following mechanisms: (1) Evaluation of the replacement of NaCN with
Zinc leaching residue (ZLR) contains high content of valuable metals such as zinc and iron. However, zinc and iron mainly exist in the form of zinc ferrite, which are
To recover Zn, Pb, Fe and Si from a lowgrade mining ore in the Lanping basin, Yunnan Province, China, a novel technology using the roasting with pyrite and
On the basis of electrochemically controlled contact angle measurements, the lowpotential, lowpH hydrophobic state of pyrite has
The finer the material, the greater is the percentage of recovery; the pyrite should pass at least a 170mesh screen in order to get efficient flotation under the conditions of the tests. Of the many factors

For example, Li et al. 32 investigated the recovery of lead and zinc from lowgrade leadzinc oxide ore by sulfidation roasting and flotation process. The results showed 79.5% Pb and 88.2% Zn were
Kooshk (Iran).The presence of organic matters and carbonaceous pyrite in these deposits influences the selectivity between galena, sphalerite and pyrite species in the flotation process [13]. The Kooshk mine is one of the largest zinc and lead deposits in Iran. The ore contains of sphalerite and galena as the valuable minerals, and
Zinc leaching residue (ZLR) contains high content of valuable metals such as zinc and iron. However, zinc and iron mainly exist in the form of zinc ferrite, which are difficult to separate and recover. This study proposed a new process involving sulfidation roasting, magnetic separation and flotation to recover zinc and iron in ZLR. Through
Copper sulphide ore deposits are of great economic significance for copper extraction. In order to enrich copper sulphides, froth flotation at alkaline pH is typically applied to reject associated gangue minerals, in particular pyrite before the subsequent pyrometallurgical treatment to extract copper from copper sulphides .The selective
In this research, the selective flotation of galena and sphalerite minerals was evaluated from a pyriterich leadzinc sample. An optimum mixture of selective collectors against pyrite and also organic/inorganic pyrite depressants was obtained in the flotation of galena and sphalerite by an experimental mixture design. The effect of different
Since dixanthogen is the species responsible for pyrite flotation X 2 + 2e 2XE 0 = 0.06 volt practice and concentrate contracts which penalise impurities in For example in a lead/zinc sulphide ore the galena can be floated first at higher using cyanide to prevent sphalerite and
The plant processes copperpyrite ores and produces copper and zinc concentrates, as well as sulfur flotation pyrites. At the Uchalinskiy OreProcessing Plant, to obtain saleable zinc concentrate, a technological scheme has been introduced of bulkpreferential flotation, with cyanidefree separation of the bulk copperzinc concentrate.
The activation properties of ammonium oxalate on the flotation of pyrite and arsenopyrite in the lime system were studied in this work. Single mineral flotation tests showed that the ammonium oxalate strongly activated pyrite in high alkalinity and high Ca<sup>2+</sup> system, whereas arsenopyrite was almost unaffected. In mineral

and pyrite concentrates. Production of a separate zinc concentrate was not considered feasible in the operation due to the highly variable zinc grade of the ore. Therefore, the zinc was recovered to the copper concentrate. Table1shows sizebysize assays of different major metals in the two ore samples ground to d80: 38 m. Ore A was
The tests were carried out on monomineral pyrite powder, ground pyrite specimens, artificially ennobled with gold microand nanosize particles (0.16+0.08 mm) and (0.08+0.04mm), flotation tailings of Gaisk copperzincgold ore and Safyanovsk coppergold ore. Gold was deposited onto pyrite from Na[AuCl4] according to available procedures [4
Recycling of flotation effluents through the ore processing plant is one of the ways of reducing both plantoperating costs and industrial impact onto the local ecosystem. Such of pyrite in the presence of calcium and sulphate ions with potassium amyl xanthate as collector. Calcium ions have significant influence on zetapotential
