Pyrite Flotation Froth Flotation (Sulphide & Oxide
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. I would suggest: 1.It will be good to find out the optimum particle size firstly. You mentioned 70um and 150 um.
Pyrite Tailings Recovery by 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
Gold Pyrite, Pyrrhotite and Arsenopyrite Recovery
One of the more common classes of ores containing gold is when gold is associated with pyrite, pyrrhotite, and arsenopyrite. This is the area of gold recovery that has probably received the most research and plant optimization support especially in light of the long history of South African industrial practice. From a reagent viewpoint, charged water soluble collectors such as
Gold Flotation Mineral Processing & Metallurgy
GOLD FLOTATION FLOWSHEET. It is obvious that the most suitable treatment for ores carrying gold and silver associated with pyrite and other iron sulphides, arsenopyrite or stibnite, will depend on the type of association.
Gold-Pyrite ores Danafloat
Where gold is associated with pyrite in base metal ores where iron sulphides are depressed and report to the tailings, a separate tailings pyrite flotation concentrate should be considered. Producing a pyrite concentrate with associated gold maximizes gold recovery.
Flotation of Pyrite Metallurgist & Mineral Processing
Effect of Size of Mineral stone on the Flotation of Pyrite. Sample mixture No. 4, used in these tests, was prepared in a manner similar to sample mixtures Nos. 1, 2 and 3, except that it was crushed to pass a 48-mesh Tyler standard screen. A partial analysis of the mixed and crushed sample showed 10.70 per cent, iron and 0.18 per cent, copper.
Flotation of Gold and Gold-Bearing Ores ScienceDirect
7. Flotation of Gold and Gold-Bearing Minerals 7.1. Differential Flotation of Natural and Liberated Gold. Experience has shown that free gold particles can be recovered selectively against pyrite, by keeping the gold particle surfaces as clean as possible of organic species and by removing any adhering slime particles (Klimpel, 1997).

Gold Flotation Mineral Processing & Metallurgy. Lime should not be used because it is a depressor of free gold and inhibits pyrite flotation. Sodium sulphide is often helpful in the flotation of partly oxidized sulphides but must be used with caution because of its depressing action on free gold.

Rcovery of gold in pyritic ores Mine Engineer.Com
The pyrite in which small amounts of gold occurs is of crystalline variety (primary pyrite). The characteristics of primary pyrite are a absence of porosity, an extreme brittleness, a resistance to oxidation, and the existence of gold possessing a weak susceptibility to magnetism (due to a fine coating of a iron compound).
Froth Flotation Method JXSC Machine
This froth flotation method is used to treat quartz sulfide ores or gold-silver-bearing pyrite and pyrrhotite containing gold telluride, pyrrhotite, chalcopyrite and other sulfide minerals. The floatable gold telluride in the ores is first produced as a concentrate, and then roasted and cyanided to expose gold and silver ores in sulfides and tellurides.
