The treatment of heavy sulphide ores of copper containing zinc and pyrite is often extremely difficult particularly if soluble copper and sulphates are present. This is usually the case in ore deposits near the surface or in tropical countries where the.influence of pyrite content on the flotation of chalcopyrite after .Chalcopyrite, a major mineral for copper production, is not exceptional. It is often in association with iron sulphide minerals, particularly pyrite and minor amounts of sphalerite and molybdenite (Habashi, 1987; Wang, 2005). Recent studies indicate that the selective separation of chalcopyrite from pyrite is very difficult due to.

QUESTION. Does pyrite affect galena oxidation and subsequent lead flotation behaviour? BACKGROUND. As early as 1910 it was noted that when pyrite was mixed with a second sulfide mineral (for example, galena, sphalerite and chalcopyrite), the second mineral oxidised more rapidly (Buehler and Gottschalk, 1910).

The separation of chalcopyrite and chalcocite from pyrite in cleaner .

Mar 16, 2018 . In this study, the differences between the separation of chalcopyrite and chalcocite from pyrite in cleaner flotation after regrinding were investigated. In the rougher flotation prior to regrinding, high chalcopyrite and chalcocite recovery were obtained in conjunction with high pyrite flotation recovery due to the.

effects of edta on selective flotation of sulphide minerals

Unwanted activation of sphalerite and pyrite by copper ions dissolved from copper minerals (mainly chalcopyrite) hampers flotation selectivity. Galvanic interaction between the sulphide minerals is considered as the main cause for such activation. Therefore, a complexing agent, EDTA, was used to prevent unwanted.

The influence of water quality on the flotation performance of .

Cu2+in copper sulphate form is known as a sphalerite activator, and Zn recovery by flotation is enhanced by increasing concentrations of Cu2+ions in synthetic water (Biçak et al., 2012). Cu2+ can also enhance the recovery of galena, chalcopyrite, and pyrite (Coetzer et al., 2003). However, the effect of increasing copper.

showing how low the levels of these minerals in the concentrates are when compared to pyrite and arsenopyrite. The use of Aero 3894 and 3418A collectors allowed selectivity in the recovery of chalcopyrite, galena and sphalerite in the three rougher floatation cells. In the copper rougher cell, we obtained recovery figures.

mineral surface. When sphalerite, pyrite or other minerals are in composite with carbonaceous minerals or silica the use of these depressants can also inhibit sphalerite recovery during lead flotation.

pyrite, FeAsS; pyrrhotite, Fe1-XS; and covellite, CuS. The major cobalt source in the ore is the mineral siegenite. Separation and concentration of siegenite by froth flotation is complicated by the mineralogy of the ore. The siegenite is often present as an intimate replacement in- tergrowth with chalcopyrite (fig. 1), sphalerite.

Copper-Zinc ores - Danafloat

The flotation separation and recovery approach is quite similar to the Pb-Zn sulphide separation process. Sphalerite is depressed with zinc sulphate addition to the grind with sodium sulphide as an option for enhancing pyrite depression. Copper is floated in the first differential flotation stage at a 10-11 pH with lime.
