OSTI.GOV Journal Article: Suppression of pyritic sulfur during flotation tests using the bacterium Thiobacillus ferrooxidans
In the late 1970s and early 1980s there were approximately 25 pyrite flotation plants operating in South Africa. These were located in the gold mining areas where the slimes dams were retreated mainly to produce a concentrate for sulphuric acid production. The gold content was 0.5g/ton of which about 50 was recovered in the concentrate. Early work in the flotation group focused on a wide

saleable copper concentrate, followed by re activation and flotation of the pyrite which is leached with cyanide to recover gold. Both trains produce a copper concentrate with significant quantities of non sulphide gangue minerals. The target concentrate grade is approximately 16 Cu, with copper minerals, chalcopyrite and chalcocite, being the most abundant copper bearing minerals in the feed

Can you list the factors affects the floatability of pyrite from refractory low grade ore.I used a Wemco lab flotation cell and aimed on analysing factors like collector dosages PAX, Activator Copper sulphate,MIBC , pH and others like pulp density and particle size 70 and 150 microns .However
Flotation tests were conducted in Hallimond tube with 1.0g pyrite sample for each test. The pyrite sample was first mixed with 30mL of deionized water in a 50mL beaker. The pH of the slurry was adjusted to the specified pH by using 0.01mol/L HCl and NaOH solution.
And selectivity against pyrite will increase in significance, exponentially. So, we might well ask if the current strong financial support for the physical aspects of flotation is misguided. For example. An actual case study the treatment of a sulphide ore. For the rougher stage, recovery beyond 85 was difficult. The rougher concentrate, at 85 recovery, could be worked up to a smelter
Flotation of copper sulphides is a traditional technique for processing the sulphide copper. The presence of pyrite in copper concentrates especially the pyrite particles that are surrounded with the chalcopyrite is the most important problem of copper ore processing that leads to a
VJ 12, 19210 Bor, Serbia Received 23.10.2006. accepted 5.12.2006. Abstract In processes such as coal flotation, the surface properties of coal pyrite and other types of gangue presents in coal plays a major role in determining its separation from coal. Oxidation also leads to the formation of various oxygen functional groups and solubleanic that can adsorb on the coal surface and
In mineral processing, poor froth flotation performance translates into both an enormous loss of revenue and an unnecessary waste of the ore reserve. In this context, Bacíspany developed a versatile new, high performance flotation cell design that can be incorporated into various flotation circuits. The main feature of this circular cell is that itprised of two separate

15/06/2020· Pyrite flotation is a result of the electrochemical interactions between the mineral surface, collector, ions in solution and grinding media. At pH 8.5, these interactions may act differently in response to grinding media and collector dosage, leading to different pyrite flotation behaviour. This was studied further in the sections below. 3.2.
