Xanthate used in selective flotation of pyrite skarn ore Iron sulfide minerals pyrite is the most common pyrrhotite is less marcasite is rare pyrite is widely associated with copper sulfide lead and zinc sulfide ores and many other non-ferrous metal mines
pyrite (FeS2) [2 3] thus separation and refinement are key processes in copper recovery Pyrite is the most abundant sulfide mineral in the Earth's crust having no overall commercial value it is regarded as a gangue mineral The most common method of separation for sulfide minerals is froth flotation [1]

Copper extraction refers to the methods used to obtain copper from its ores The conversion of copper consists of a series of physical and electrochemical processes Methods have evolved and vary with country depending on the ore source local environmental regulations and other factors
Arsenopyrite is separated from a mixture with pyrite by contacting the mixture with a sulfitic agent providing HSO3- ions at elevated temperature and pH below about 8 for a period sufficient to impart a selective depression property to the arsenopyrite On addition of a collector the pyrite is rendered floatable enabling froth flotation to achieve a concentrate rich in pyrite and tailings

How to Extract Precious Metals From Sulfides Crushing begins the separation process by preparing the ore to be floated in water First the ore is crushed using a gyratory crusher to reduce the ore to 6-inch diameter pieces Then wet grinding mill grinding and/or semi-autogeneious grinders are employed to reduce the ore particles to
The aim of the research programme is to investigate the potential of flotation for the separation of arsenopyrite and pyrite minerals The efficient separation of pyrite and arsenopyrite by a cheap process such as flotation has long been recognized as a desirable technological goal for
In this research the selective flotation of galena and sphalerite minerals was evaluated from a pyrite-rich lead-zinc 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 collectors and pH values were investigated in the
Dec 03 2010These and other needs are addressed by the various embodiments and configurations of the present invention The invention is directed generally to sulfoxy reagent-assisted flotation separation of valuable metal sulfide minerals from other sulfides particularly pyrite marcasite pyrrhotite arsenopyrite and other gangue minerals
In the ore selection process magnetite is the major recovery of minerals To ensure the quality of magnetite the magnetite should be separated from the magnetite mining pyrite and pyrite As the magnetite and the magnetite mining pyrite are all strongly magnetite mining minerals it is easy to achieve separation in the week magnetite mining

flotation separation arsenopyrite The aim of the research programme is to investigate the potential of flotation for the separation of arsenopyrite and pyrite minerals The efficient separation of pyrite and arsenopyrite by a cheap process such as flotation has long been recognized as a desirable technological goal for More Detail
However crystal form if observable provides a conclusive separation The streak of pyrite can be slightly greenish while marcasite is a pure gray In reflected light microscopy of polished coals and ore specimens marcasite will have a noticeably whiter color than the brass yellow of pyrite although inexperienced observers might see them

Abstract In this paper the flotation separation of chalcopyrite-pyrite has been studied in the presence of sodium humate Results of single mineral tests indicate that sodium humate is a good depressant with high selectivity and pH values and calcium ions in pulp influence the activity of sodium humate
A process of separating copper minerals from pyrite wherein a flotation concentrate containing copper minerals and pyrite is reground in the presence of lime and subsequently conditioned at a pH of 12 0 or more for a predetermined period sufficient to depress the pyrite with optional additions of sulf-hydryl collector cyanide and dispersing agent and the conditioned pulp is subjected to

between serpentine and pyrite is intense Sodium hexametaphosphate could effectively disperse serpentine and pyrite In order to further investigate the effect of sodium hexametaphosphate on the flotation separation of serpentine from pyrite the adsorption quantity of PAX on artificial mixed ore (pyrite 15 g/L serpentine 5 g/L)
the adsorption density of a collector on the pyrite surface but also reducing the flotation recovery PAAS increased the flotation recovery of pyrite by promoting dispersion between pyrite and serpentine The effective flotation separation of pyrite from the refractory iron sulphide ore
As flotation also can be used for pyrite ore separation though flotation separation has deficiency with considerable large investment in equipment higher mining cost while better efficiency and index in mining with simple flotation reagents so flotation methods can be used for low grade pyrite ore
