Oxidative hydrometallurgy of sulphide minerals f.R.Carrillo-pedroza, m.J.So ria-aguilar, e.Salinas-rodrguez,.The dissolution of pyrite to ferrous ions in an acid medium proceeds through the formation of an iron-deficient or a sulfur-rich layer rather than elemental sulfur.
Mechanism of sphalerite depression in an open cuzn flotation separation circuit l.Xia1, b.Perseverance deposit the bracemac-mcleod base metal mine, mine matagami-une compagnie glencore,.Inadvertent activation of sphalerite by dissolution of copper ions from complex sulphide ores has been been reported in many instances chandra and.
Bioleaching of copper sulphide flotation concentrate in batch reaction system using.High pulp densities and high heavy metal concentrations,.1.8 to 2.2 and high fe3fe2 ions ratios 8.The bioleaching of sulphide minerals is based on the ability of acidophilic microorganisms in oxidizing ferrous.
A method of using the synergy of multiple depressants to improve the depression of iron sulphide without compromising the recovery of the valuable sulphide minerals in the flotation of non-ferrous metal sulphides, while reducing or eliminating the use of environmentally problematic chemicals such as polyamines.
Micro-cracking on the flotation of low grade nickel sulphide ore.The.Mechanical recovery of sulphide and the metal content of the concentrates remain low.The gangue minerals of the ore are.Flotation calcium ions improves the absorption of xanthate, especially on the nickel and copper sulphide.
However process water chemistry may be a critical issue to flotation efficiency.Process water discharged from sulphide flotation circuits are usually gypsum caso4.H2o saturated and have a high salinity.The major ionic species contained in the process water are ca2 and so42- ions.
Flotation separation of complex sulphide orespresent state and trends effect machanism of copper ions on sulphide oresa study.
,sulphide ore 1sulphide ore 1.According to lab and pilot test results and the situation of capital construction progress,the development thinking,full dump leaching and half dump leaching to treat oxidized ore,flotation to treat sulphide ore,developing oxidized ore and sulphide ore together early,and strengthening test study of yulong copper mine were expounded.
Inf luence the flotation.Copper ions are added to activate the flotation of sulphide minerals and magnesium ions are present due to dissolution from magnesium bearing minerals such as chlorite and brucite 16.Flotation tests were also carried out at ph 9 u.
Water quality on the flotation of galena, sphalerite, chalcopyrite, and pyrrhotite was carried out using asymmetrical fractional factorial design.The multivariable analysis showed that of ten studied factors, six cu2, zn 2, mg , ca2, so42-, and pax have a significant influence on the flotation of these sulphide minerals.
The processing of climax molybdenum ore, which is of or even shape and dissolved ions concentrations, play an a finely disseminated nature, most of the loss in the important role in determining the flotation of fines of.Flotation of the 8sofo -44-jlm feed is in the -si.Lm size these minerals.
Effect of water composition on flotation of lead and.Metal ions in these water resources were adsorbed on the ore whilst ions associated with gangue minerals were released into the flotation pulp this paper includes a research for the effect of different water compositions on lead and zinc sulphide flotation.Live chat.
It is added to the slurry prior to the flotation.It precipitates heavy metal ions from the solution thereby acting as deactivators.But they dissociate to a greater extent into oh- and hydrogen ions, which further modify the zeta potential and hence, the floatability of the mineral.26 27.
An important first step entails ensuring the sphalerite surface is not activated with dissolved metal ions, which then makes the sphalerite non-floatable.The established lead-zinc ore flotation processing scheme is to add zinc sulphate znso4 to the grind to control metal ion activation sphalerite depression.
The reasons may differ.Some sulphide minerals can be floated without collectors, while others require small quantities of collectors.Chander 1999 reported the various reactions in sulphide mineral flotation such as the oxidation of the minerals, hydrolysis of metal ions, decomposition of metal salts and.
Metal hydroxides decreases the hydrophobicity of the mineral and alters the collector adsorption making it less selective toward the various sulphide minerals senior and trahar, 1991 clarke et al., 1995.In this study, a copper sulphide ore has been articially oxidised for varying lengths of time and a series of grinding and otation.

The various water resources employed during lead and zinc flotation caused activation, depression or selectivity effects on minerals due to the presence of different ions in solution.Metal ions in these water resources were adsorbed on the ore, whilst ions associated with gangue minerals were released into the flotation pulp.This paper.
Pdf effect of water composition on flotation of lead.Metal ions in these water resources were adsorbed on the ore, whilst ions associated with gangue minerals were released into the flotation pulp.This paper includes a research for the effect of different water compositions on lead and zinc sulphide flotation.
The next section describes these effects on the flotation of specific sulphide minerals.Effect of grinding media on sulphide mineral flotation significant progress has been made in recent years in identifying the role grinding media can play in flotation.
