Sodium ethyl xanthate is a collector with better selectivity, widely applied in flotation of Cu/Zn/Ne and pyrite, especially for the gold flotation in gold and copper mine. It could make good result in the copper and lead oxidized ore, normally used in rough selecting and scavenging.
From my understanding, you would like to get a high pyrite flotation recovery because the gold is locked in the pyrite. And you are trying to analysing the effect of various factors on pyrite flotation.
Pyrite has long been used as a source of sulphur, and its recovery as a by-product from the flotation of certain base metal ores is a well established practice. Large tonnages of mill tailings which have accumulated as a result of various milling operations frequently contain significant amounts of pyrite. In many instances these tailings can be treated to yield pyrite concentrates that are a ...
The flotation concentrate contains pyrite,Beneficiation of the gold bearing ore by gravity and flotation Gold concentration usually consists of gravity separation, flotation, cyanidation, or the combination of these processes.
Conditioning in the flotation of gold, uranium oxide, and pyrite by F.J.N. STASSEN* SYNOPSIS The effect of conditioning energy on the flotation of gold, UaOe, and pyrite was investigated in the range 0,1 to 100 kWh per tonne of dry ore for various combinations of conditioning time and impeller speed in a cylindrical conditioning tank.
May 04, 2018· gold ore flotation machine for pyrite ore copper ore offers 4502 silver ore products. About 17% of these are mineral separator, 6% are vermiculite, and 1% are copper ore. A wide variety of silver ore. Quotation More. Sulphide Ores, Sulphide Ores Suppliers and Manufacturers at .
The flotation of auriferous pyrite in gold leach residues through traditional techniques is only possible after conditioning with sulphuric acid to overcome depression by cyanide and hydroxide.
Abstract Copper-gold-pyrite ore types (with elevated pyrite content) are typically found in complex ore bodies which require a sequential flotation method to recover two products (copper - gold and
Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity.Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.

Role of starch and metabisulphite on pure pyrite and pyritic copper ore flotation 43 occurred with 1.7 mg/ dm3, while 21% depression occurred with the same dosages of starch at pH 6.5 where pyrite flotation is expected to be weak at pH 10.
Selective flotation of gold from pyrite under oxidizing conditions The use of hydrogen peroxide as an oxidizing agent in the selective flotation of gold from pyrite with potassium amyl xanthate was studied by contact angle and electrophoretic mobility measurements carried out under similar conditions.
Flotation Separation of Arsenopyrite from Pyrite This invention relates to beneficiation of ores and, more particularly, to a process that preferentially renders arsenopyrite (FeAsS) unfloatable while leaving pyrite (FeS 2 ) floatable.

A significant portion of the gold in Witwatersrand ores may occur in the pyritic fraction, which seldom comprises more than 4% of the ore. Consequently, pyrite recovery through flotation offers ...
Pyrite is removed from coal by a 2-stage froth flotation. In the 1st stage, coarse pyrite is removed as underflow in a conventional froth flotation operation. In the 2nd stage, the froth product from the 1st stage is subjected to froth flotation by using a coal flotation depressant and a pyrite ...
The separation of tellurides from pyrite can be carried out by selective flotation. The selection and dosage of collectors and pulp pH are very important to produce one concentrate containing tellurides and free gold, and a further concentrate containing pyrite.

However, it is difficult to separate the magnetite and the magnetite mining pyrite. magnetite mining pyrite is the iron sulfide mineral with weaker floating property and it is easy to be suppressed, so appropriate adjusting agent is necessary to strengthen its flotation.
Pyrite,pyrrhotite and arsenopyrite are sulphide minerals which bear iron in their structures and are collected in flotation plants by thio-compounds, for example: xanthates,
Kinetics of semi-batch flotation behavior of a gold ore from North-Western Quebec, Canada was investigated with respect to fineness of grind (P 80).The gold was mostly associated with pyrite in native form as inclusions and was also in contact with pyrite along the boundaries of non-sulphide gangue.
Flotation results indicate that PIONERA BioPolymers, at each dosage, significantly reduce pyrite than conventional pyrite depressants. Additionally, conventional pyrite depressants such as sodium cyanide, sodium hydro sulfide and Nokes reagent are toxic, highly regulated, difficult to handle and present an overall costly alternative.
