Copper Sulfate In Gold Flotation. The role of copper sulphate in pyrite flotation. The role of copper sulphate in the flotation of pyrite has been studied. A survey of a number of pyrite flotation plants using copper sulphate showed that in correct dosages it was able to increase both grades and recoveries. This was confirmed in batch tests

flotation of copper ox ide ore, showed that fl otation recovery increas ed by 12.28% when ammonium sulphate was added in the presence of sodium sulphide. The hig hest recovery was obtained when

Jul 09, 2019 1 Types of copper sulfide ore (1) Single copper mineral Its ore characteristic is relatively simple, and the only useful component that can be recycled is copper. The gangue minerals are mainly quartz, carbonate and silicate. (2) Copper-sulfur ore Called copper-bearing pyrite. In addition to copper minerals, iron sulfide can be recovered, and the main mineral of

Jan 01, 1988 The addition of copper sulphate enhances the rate of pyrite flotation and the grade of concentrate. The role played by copper sulphate is not entirely clear, and a number of theories have been proposed to explain the observed effect. Firstly, it has been suggested that copper ions are adsorbed onto the pyrite surface, thus modifying the surface

Mar 01, 1997 With collector AF 211, copper sulphate has little effect on the recovery and flotation rate of sulphur. Gold recovery is decreased with the addition of copper sulphate at pH 4.7 - 8.0 but is increased at the higher pH of 11.0. The flotation rate of gold is improved at all pHs by the addition of copper sulphate

Beside plants, cattle, sheep and horses can all receive foot baths containing copper sulphate to help prevent and treat fungus. Another large application of copper sulphate is in mining industries where it is used in the flotation process mainly in lead, zinc and gold mines. In metals industry, copper sulphate can be used in copper plating

Mar 05, 2021 Gold flotation reagents can be divided into 5 types: collectors, foaming agents, inhibitors, activators, and pH regulators. Flotation reagent is one of the key factors affecting the flotation of gold ore. It can adjust the surface properties of gold ore during the flotation process, and improve the flotation speed and selectivity. This article will briefly introduce the working

Mar 15, 2019 Among the flotation reagents, commonly used activators for flotation are sulfuric acid, sulfurous acid, sodium sulfide, copper sulfate and so on. Inhibitors: It is a kind of reagents mainly used to increase the hydrophilicity of minerals and to form a hydrophilic film on the surface of the ore particles in flotation process

Jul 12, 2021 Copper and sulfur in copper ore have strong collection properties, which is also conducive to improving the recovery of associated gold in copper sulphide ores. The flotation effect of refractory copper-sulfur ore containing secondary copper minerals is better than that with butyl xanthate, but its selectivity is worse

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. Xanthate, dithiophosphate and thionocarbamate collectors are used as explained much more extensively in the copper flotation section

Copper Sulfate as Flotation' Activator for Sphalerite BY 0. C. RALSTON,* C. R. KING* AND F. X. TARTAHON,* CLARKDALE, ARJZ. (San Francisco Meeting, October, 1029) THE use of copper sulfate for improving the flotation behavior of sphalerite is probably at lcast 15 years old. The original discovery of its activating influence is somewhat obscure

Jul 13, 2016 Copper sulphate is frequently helpful in accelerating the flotation of pyrite and arsenopyrite. In rare instances sulphuric acid may be necessary, but the use of it is limited to ores containing no lime. “Ammo-phos,” a crude monoammonium phosphate, is sometimes used in the flotation of oxidized gold ores

Feb 01, 2001 Activators The use of copper sulphate as an activator for the surface of pyrite is common. In early studies copper sulphate was also considered to be an activator of the gold surface (Leaver and Woolf, 1934). However, more recent studies have shown it not to affect the floatability of gold using xanthate at a pH of 11.3 (Duchen and Carter, 1986)

Apr 13, 2016 Flowsheet for treatment of Copper Sulfide ores rich in minerals such as chalcopyrite with gold and silver as well as arsenopyrite The above flowsheet is designed for the treatment by flotation of copper as chalcopyrite with gold and silver values. The ore, ranging from 60-65% silica, with pyrite, arsenopyrite, and calcite with 3 to 4% copper

Oct 02, 2016 Copper sulfate, when used as an activator in flotation of sphalerite, forms an invisible but physically detectable film of cupric sulfide on the surface of the sphalerite particles, as evidenced by increased electric conductivity, by chemical metathesis, and by the ability to deactivate with solutions of alkali cyanides, which are known as solvents of copper sulfides

Jun 05, 2014 Table 2 shows that the gold concentrate with the grade of 25.14 g ton −1 and the recovery of 86.94 % is obtained through direct fine grinding flotation process, one rougher, three cleaners, and four scavengers under the condition of the grinding fineness of 0.074 mm (96 %)

Oct 17, 2016 Whichever reagent is used, it is better to introduce it into the cleaning circuit if possible, because any excess entering the machine through occasional faulty control is likely to cause a lower gold loss there than in the roughing circuit. The addition of copper sulphate up to 0.25 lb. per ton is sometimes found useful in speeding up flotation

Jan 01, 2016 It is widely accepted that the main purpose of copper sulfate in the flotation of sulfide gold carriers is to enhance the flotation of the sulfides and, in particular, pyrrhotite (Mitrofanov and Kushnikova, 1959), arsenopyrite (Gegg, 1949, O'Connor et al., 1990), and pyrite (Bushell and Krauss, 1962). The sequence of copper sulfate addition (before or after the

The copper sulphate (CuSO4) is widely used as an activator in the gold flotation, but, its role is still not entirely clear (9, 41). Too high an addition of copper sulfate is known to have

Jul 01, 2019 Copper sulphate can activate pyrite and arsenopyrite to promote gold recovery in the flotation process. The results of the investigation on the effect of the dosage of CuSO 4 on the recovery of gold are shown in Figure 11C
