The role of sodium metabisulphite in depressing pyrite in ...

01/10/2019  It is observed that MBS is generally used in copper flotation using seawater. However, it is added in the mill in some plants, but during flotation in the other plants. The dosage of MBS added also varies significantly in these plants. A fundamental study may provide knowledge to guide the application of MBS in copper flotation using seawater.

The effect of sodium metabisulfite and ...

01/08/1999  For Test 3, SMBS was introduced prior to flotation at 0.60 kg/tonne and conditioned also for 3 min followed by a second (0.60 kg/tonne) and third additions (0.30 kg/tonne) after removal of second and third concentrates, respectively. Addition of SMBS caused the pH value to drop to approximately 7.2, which was then adjusted to the 9.5 level by addition of lime.

Electrochemistry of Copper Activation of Sphalerite and ...

Although copper sulfate was used as an activator many years before xanthate was adopted to flotation, it is believed that copper activation of galena was accidentally introduced to galena flotation in 1914 (Ralston, et al, 1930).

ROLE OF STARCH AND METABISUPHITE ON PURE PYRITE AND ...

Shen et al. (2001) studied the effect of sodium sulphite on the flotation of sphalerite and pyrite in the presence of copper ions and they reported that sulphite promoted the formation of copper hydroxide on the surface of pyrite leading depression. Yamamoto (1980) proposed that sulphite ions depressed pyrite by desorbing xanthate species from the surface.

MECHANISM OF SPHALERITE DEPRESSION IN AN OPEN CU/ZN

Plant and laboratory test work was performed in order to optimize a copper/zinc flotation separation circuit at Matagami concentrator, Canada. The testing identified a significant difference between the laboratory testing and the plant flotation, particularly for the sphalerite recovery in the rougher copper concentrate. Tests indicate that sphalerite recovery of the flotation concentrate in the laboratory

Sodium Metabisulfite for Mining Industry-Qingdao Tianya ...

Sodium Metabisulfite is widely used for mining industry. Methods of mineral processing are as follows: Flotation: Flotation is the technique of separating useful minerals from the ore, based on the physical and chemical properties of mineral particles. Almost all of the ore can be used in flotation separation.

Electrochemical Studies of Copper-Activation of

At very low potentials, however, elemental copper is formed, which may worsen the selectivity of the sphalerite flotation. Controlled potential contact angle measurements showed that xanthate adsorption does occur on copper-activated sphalerite at all pH ranges. However, the contact angles and flotation recovery decrease at near neutral pH. This problem is caused by the adsorption of the ...
