2 17.Flotation of gold ores.Also for beneficiation and separation of difficult-to-treat refractory gold ores.Flotation is also the best method for recovery of gold from base metal ores and gold-containing pgm ores.Excluding gravity preconcentration, flotation remains the most cost-effective bene ficiation method.
Fatty acids, particularly oleic acid, are extensively used, with reasonable success, in the flotation of colored minerals from feldspar ores.In this study, potassium oleate, oleoyl sarcosine and hydroxamate were used to float colored impurities both before and after magnetic separation.

With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market.In over half a centurys practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.

Flotation is a selective process and can be used to achieve specific separation from complex ores such as lead-zinc, copper-zinc, etc.Flotation machines are subject to coarse separation, swept separation, fine separation and floatation, so the useful ore are reclaimed.

Flotation and chemical processing methods were combined for treatment of low-grade ferberite ores from the boulder county, colo.Area to produce specification-grade synthetic scheelite.Flotation research was focused on attaining plus 90 recovery in concentrate containing 10 wosub 3.
Although the processing of mineral ores is by far the largest use of flotation separation, numerous other processes have been developed for the separation of other materials.These range from coal flotation processes for upgrading its fuel value to solution processes for separating biomolecules and ions.
The invention relates to the enrichment process, in particular to flotation separation methods of the minerals copper, nickel and waste rock, forming part of cuprous ores with complex mineralization, highly developed border sulfide and non-metallic minerals and the most rebellious in comparison with other types of copper-nickel ores.
Flowsheet for treatment of copper sulfide ores rich in minerals such as chalcopyrite with gold and silver as well as arsenopyrite.The above flowsheet is designed for the treatment by flotation of copper as chalcopyrite with gold and silver values.The ore, ranging from 60-65 silica, with pyrite, arsenopyrite, and calcite with 3 to 4 copper.
The importance of the flotation process to the economy of the whole industrial world is considered enormous.Without this process, many familiar metals and inorganic raw materials would be exceedingly scarce and costly because the highgrade ores that could be processed by simple physical and mechanical methods have long since been used up 1.
Froth flotation is the most effective industrial method used to separate fine-grained minerals.The main problem of complex ore flotation is the negative effect of interactions among minerals in slurry, leading to variation in surface properties during separation.In this review, studies on the interactive effect among minerals on the flotation of iron ores, magnesite ores, and scheelite ores.

Flotation of gold and gold-bearing ores 327 generally between 7 and 9.Flotation may be carried out at higher ph values of 9 to 10, since this favours the depression of talc minerals and avoids the use of expensive gangue depressants.Copper minerals are oated in alkaline circuits.
Selective separation of sulphide minerals can be achieved using a variety of collectors and modifiers to adjust surface properties 10,12-14.In practice, when treating complex sulphide ores, the combination of depressants is common, especially when separation of several valuable minerals is required for better selectivity.
Flotation separation ores and agents.Oct 31 1989 a new depressant for use in enhanced separation of polymetallic sulphides is described the depressant agent is used in conjunction with conventional collector agents and frothing agents in the flotation separation of copper nickel lead zinc sulphides by depressing iron sulphides such as pyrrhotite pyrite and marcasite in the tailing.
The encapsulated liquid can contain a depressant composition for the enhanced separation of copper, nickel, zinc, lead in sulfide ores in the flotation stage, for example.The shell 114 can be used to encapsulate a powder which can have a magnetic property so as to cause the synthetic bead to be magnetic, for example.
