Pyrite is one of the major diluents of copper, lead and zinc concentrates. One explanation for the high flotation of pyrite in alkaline pH conditions is its inadvertent activation by copper either dissolved from copper minerals present in the ore or added in the zinc circuit to activate the flotation of sphalerite Bushell and Krauss, 1962 ...

zinc and pyrite (recovering of gold and silver) from the bulk flotation tailings was used based on the ore characteristics. The concentrate indexes of the grade of copper, .
We have pyrites mine flotation cell for pyrites ore separating,Features. Flotation technology mainly utilizes difference of chemical and physical properties of mineral surface to separate mineral particles, which is also called floating separation in the past. It is one of the most commonly used ore beneficiation methods. The main equipment of flotation separation plant is jaw crusher, ball ...
In this research work, selective depression of pyrite in the flotation of a lowgrade lead–zinc ore containing 31% pyrite was investigated in the absence and Know More. PYRITES Online Information article about PYRITES .
Flotation of pyrite is possible below pH 11 with short chain xanthates, but is depressed above about pH 11 Depression of Pyrite 1. ... practice and concentrate contracts which penalise impurities in For example in a lead/zinc sulphide ore the galena can be floated first .
Flotation depressants abstract This investigation was performed with samples from a lead–zinc sulphide deposit aiming at studying the influence of the dispersion degree of the particles in the pulp on lead and zinc flotation. Samples of ore and also of the minerals sphalerite, galena, pyrite, and dolomite were selected for the experiments. Nine

Flotation of copper at different alkaline pH from 7upto 10 and using different Xanthates as collector vs. recovery of copper may give some clue. Minimum Pyrite obtained in copper concentrate is the starting point for further flotation test work. Depressing Pyrite is always a tricky matter.
According to the refractory leadzinc ore properties with high pyrite, the experimental studies were conducted on floatation reagent conditions and closed circuit tests for comprehensive recovering of all types useful minerals. In comparison to the test results of different process flowsheets and different types of flotation reagents, adopting prior flotation lead (Pb)—Zn selective flotation ...
The same approach applies to the zinc circuit: sphalerite particles must be disperse and aggregation of pyrite and dolomite might favour the rejection of these species to the decades of investigation were necessary in order that some correlations between dispersion and flotation performance in iron ores reverse ionic flotation were established (Peres and Silva, 1994;Peres et ...

low zinc (Zn) ore was fed to the plant. Marketable copper concentrate at 9195% recovery was produced utilizing a highpH bulk sulphide rougher flotation and 2 cleaning stages. Because of increased levels of Zn of the ore body, a Cu/Zn separation circuit was initiated in early 2010 following an intensive laboratory test work program.

2004). Pyrite depression with dextrin occurs around pH 8 so using dextrin could lower the pH in flotation processes operating at high pH such as the flotation of copper in porphyry ores and flotation of zinc in polymetallic basemetal sulfide ores. Furthermore, dextrin could be used as a pyrite
