Optimization of physicochemical parameters of …
23-9-2016 · Tailings issued from polymetallic ore flotation of Chaabat el-Hamra mine contain sulfides such as Galena (PbS), Pyrite (FeS2) and Chalcopyrite (CuFeS2). They present environmental threats such as the acid mine drainage. stone analysis showed that the major element of these tailings is Pyrite. The processing of the latter eliminates much of the sulfur. The flotation is based on the ...

The Flotation of Pyrite using Xanthate Collectors
Oxidation of pyrite in air showed a marked effect on the flotation properties of pyrite. In alkaline surroundings the recoveries were reduced by 30%. This effect was not observed during flotation in acidic solutions, since in situ leaching was taking place thus removing the oxidation products from the pyrite …
Study of Flotation Parameters for Copper Recovery from ...
grained pyrite , performs interstitial 100-500 microns by size [16]. Intergrowth of pyrite, sphalerite, tennantite and other copper sulphides, difference in their activity and size create the considerable problems in implementation of selective flotation, obtaining conditional copper and zinc concentrates.
Extracting gold fines from pyrite slag by …
In order to extract gold fines from pyrite slag, the hydrophobic flocculation flotation (HFF) was studied and compared with conventional flotation. The main parameters of HFF such as flotation reagent, surfactant dosage, the duration of agitation and the amount of non-polar oil were investigated, and the effect of non-polar oil was analyzed ...

Flotation Froth - an overview | ScienceDirect Topics
In addition to the two primary flotation agents there are also a number of modifying and conditioning reagents, which control a variety of ore and flotation circuit variables [13]. For instance, lime is a depressant for pyrite (FeS2) in the flotation separation of copper sulfides.
pyrite in zinc ore flotation - colorholland.nl
Sodium silicate was somewhat effective in causing a differential or selective flotation of copper, as chalcopyrite from pyrite by keeping pyrite from floating. Sodium hydroxide and sodium sulfide gave, in most cases, a distinct separation of sphalerite from chalcopyrite; i.e., a high copper and low zinc by suppressing the flotation of sphalerite.
The practice of pyrite flotation in South Africa and ...
The flotation of pyrite is of great importance to the gold mining industry in South Africa and Australia. The flotation plants fall into a number of categories, viz. flotation after milling, flotation of current residues and reclaimed residues, flotation of refractory ores and the flotation of gold-copper ores.

Column Flotation Parameters
Investigation of coarse bubble column flotation resulted in identification of four distinct beneficiation zones of a flotation column. Comparison of average normalised percent mineral upgrading per foot values (zkn) indicated the relative degree to which these zones contribute to overall column mineral grades and recoveries.
