Copper and xanthate adsorption onto pyrite surfaces

21/11/2012· Further details of pyrite copper activation and flotation are provided in Chandra and Gerson (2009) and references therein. Despite decades of research and widespread use in industrial mineral processing circuits, the exact Cu activation of, and collector adsorption mechanism onto, pyrite and the related surface speciation are poorly understood.

Growth of minerals in the pyritic copper ore: chalcopyrite (kp) and sphalerite (sf) phases locked with cataclastic pyrite (pi) structure 2.2. Method Experimental studies have been carried out with Denver flotation machines using 40 g of -100 μm pure pyrite in one dm3 cell for pure pyrite study and 1 kg of approximately 53 μm ore sample in 2.5 liter cell for pyritic copper ore study. An agate

Copper-Cobalt ores Danafloat

These are often associated with copper minerals and pyrite and pyrrhotite iron sulphides. Two different flotation separation strategies are used. Differential flotation sequence: A differential copper-cobalt flotation separation which begins with selective copper flotation by raising the slurry pH to 10 with lime and using a dithiophosphate copper collector. The tails produced in the first

Sodium Metabisulfite MBS for pH Control and Pyrite

17/3/2017· It is also used to prevent flotation of sphalerite by copper activation in the presence of Tennantite/Covellite in the ore. For pyrite flotation, you see maximum iron/pyrite depression using Sodium Metabisulfite/MBS takes effect at around pH 6. MBS will depress metals/minerals in the order as dosage increases: Fe/Iron (Pyrite) Zn/Zinc (Sphalerite) Pb/Lead (Galena) Cu/Copper (Chalcopyrite)

Copper Flotation Mineral Processing & Metallurgy

19/3/2017· In most plants engaged in the flotation of ores containing copper-bearing sulphide minerals with or without pyrite, pine oil is employed as a frother with one of the xanthates or aerofloat reagents or a combination of two or more of them as the promoter. Lime is nearly always used for maintaining the alkalinity of the circuit and depressing any pyrite present. The reagent consumption is

Separation efficiency improvement of a low grade copper

The recovery of gold-containing pyrite to the copper concentrate is encouraged to achieve a higher total gold recovery provided that a saleable copper concentrate grade is still produced. Mineralogical diagnosis of feed and product streams from the copper flotation circuit have shown that the copper bearing minerals are well liberated and thus further liberation of the copper minerals was not

fluorine -bearing minerals in samples of final copper concentrates and the distribution of fluorine amongst the minerals. Quantification of each mineral in mill feed and various flotation streams at Ok Tedi enables an understanding of the quantitative response of fluorine bearing minerals to flotation. The metallurgical behaviour of fluorine in the flotation process is also discussed

Froth flotation Wikipedia

The development of froth flotation has improved the recovery of valuable minerals, such as copper- and lead-bearing minerals. Along with mechanized mining, it has allowed the economic recovery of valuable metals from much lower grade ore than previously. History 19th century. Descriptions of the use of a flotation process have been found in ancient Greek and Persian literature suggesting its
