Flotation Method Applicable copper ores: copper sulfide ores, such as chalcopyrite, bornite and chalcocite, as well as common copper oxide ores.Copper Ore Processing Plant,Equipment For Sale ...

I experienced a coppergold massive ore type where thionocarbamate seemed to work better. Also, SMBS is a common pyrite depressant. Dithionocarbamates are very selective in copper flotation. It will not float pyrite. Can be used at a slightly elevated pH (9). It is a common approach in copper flotation.

Using a range of ore samples from the same deposit the influence of mineralogy on flotation performance was studied. Characterisation of the samples through QEMSCAN showed that bornite, chalcopyrite, chalcocite and carrollite are the main copperbearing sulphide minerals while carrollite is the only cobaltbearing mineral.

chalcocite, and the native metals, gold and copper. ... have a plant design that depends upon the specific ore characteristics and the ... almost all cases, the plant design parameters and processes used for beneficiation are dependent upon.

2. Flotation of middling particles ( higher than 200 µm) improves with increased pH. This is true in the case when chalcocite is the major copper mineral. In the case of chalcopyrite ore, a lower pH is more desirable ( –) because at a higher pH, the flotation of chalcopyrite is decreased, especially for the coarser particles.

order to judge the influence of these parameters on flotation results of similar ores. The Nussir ore primarily contains three copper minerals: chalcopyrite, chalcocite, and bornite. The undesirable minerals are predominantly silies and carbonates. Chalcopyrite is one of the abundant commercial sources of copper. However, chal

One kilogram of ore, at 200 mesh was used as feed to the bulk flotation that was conducted for 8 minutes. Two collectors, independently added, were used at 3 different dosages: 20, 30, and 40 g/ton. The copper and zinc contents were determined as well as their respective recoveries in the bulk concentrate.

Copper can be found in more than 200 minerals, but only about 10% of this occurs in the form of sulphide minerals (, chalcopyrite, bornite and chalcocite) or oxidized minerals (, cuprite), which are of significance as copper ores (Lossin, 2001).Depending mainly on the ore type, as well as the geographical, economic and environmental considerations, copper can be extracted through:

A New Appliion For Flotation Of Oxidized Copper Ore Key Words Oxidized copper ore sulfurization flotation copper cobalt sulfur Pyrite chalcopyrite and oxidized copper ore are the main ore minerals density The studies were carried out at pH 87 holding other parameters constant and Chat Now.

Chalcocite is the most important and abundant secondary copper ore in the world with a rapid dissolution of copper in an acidchloride environment. In this investigation, the methodology of surface optimization will be applied to evaluate the effect

The separation of chalcocite (Cu 2 S) and heazlewoodite (Ni 3 S 2) from high nickel matte can be achieved by maintaining the proper pH and pulp potential while using xanthates as flotation recovery of Cu 2 S and Ni 3 S 2 has been studied by adjusting the oxidation–reduction potential of the flotation pulp with (NH 4) 2 S 2 O 8 and KMnO recovery of Ni 3 S 2 is almost zero ...

In the Flotation Plant Bor, the section C was originally designed for flotation of ore, and later adapted for flotation of slag [3]. The process of slag comminution in the plant consists of crushing and grinding. However, the ore is suitable for comminution from the standpoint of consumption the energy, linings and grinding bodies of

and the flotation concentrate produced from the ore. Accordingly, copper was identified to be present as sulphides including chalcopyrite, covellite and chalcocite in the ore (Figs. 1 and 2). Pyrite and sphalerite were also observed as the other sulphide phases (Fig. 2). High copper content renders the ore refractory in .
