Request PDF on ResearchGate | On Jun 30, 2015, Nestor Cruz and others published The interaction of clay minerals with gypsum and its effects on copper–gold flotation.
the flotation recovery of Ni, Cu and Co from a nickelcopper sulphide ore. The effect on flotation performance of various parameters such as pH, collector dosage, % solids and depressant dosage at different levels was investigated. Therefore, the main objective of the study was to optimize the process
effect of using seawater as process water was investigated by using different type of collectors. The object of the second phase was to conduct flotation tests in synthetic seawater and tap water with varying dosages of lime, and observe the effects on pH, and on the recoveries of copper.

The useful minerals of Jinchuan highgrade copper and nickel suphfide ores were mainly nickel and copper, whose grade were respectively % and %. The content of MgO and SiO2, main gangue components, reached %. The key to improve the separation indexes of flotation concentrate was to inhibit the gangue minerals effectively, therefore, the effects of different kinds of regulators on ...

The addition of electrolytes considerably increases the recovery of mineral matter in coal flotation. In this paper, the effect of calcium ion on coal flotation in the presence of kaolinite clay was investigated through microflotation experiments on a mixed coal–kaolinite system. The interaction behavior and mechanism between coal particles and kaolinite were indicated by a rotational ...
Figure 1: The flotation system includes many interrelated components, and changes in one area will produce compensating effects in other areas (Klimpel, 1995) Froth flotation is a good example of an engineering "system", in that the various important parameters are highly interrelated, as .
copper industry may be found in chapter 10. AIR QUALITY Pollutants of Concern and Their Regulation Uncontrolled copper smelting processes emit large quantities of particulate matter, trace elements, and sulfur oxides, which can have adverse effects on human health. Sulfur dioxide (SO 2), and the sulfates and sulfuric acid aerosols it forms
Copper is traditionally known as the "red" metal after its natural color. However, it is also known as a "green" metal for the green patina that it acquires due to weathering. Indeed, patinized copper is the architectural focal point of many modern buildings for its natural look.
flotation experiments, including the addition in the flotation conditioning stage and 4 minutes lasting frothing. Fig. 3: The variation of the pulp potential as a function of time after addition of 16kg/t Na 2 S and aeriation. Effects of solid percent and pH at low level of Na 2 S
As an example of the beneficial effect of copper sulfate in the activation of zinc sphalerite toward flotation, the series of results shown in Fig. 1 is of interest. These represent rougher tests on a sample of heavy pyritic ore. The particular sample in question contained about % zinc as marmatite; and was treated in a circuit made alkaline with lime, using pine oil as a frother and ...

The effect of copper sulphate addition on the recovery of chromite generally neutral in charge. As a result of this charged nature, CMC adsorption can induce particle dispersion in addition to having a depressant effect which can influence flotation performance (Shortridge et al. 1999; Dalvie et al. 2000).
effect of bentonite on copper flotation through reducing the high pulp viscosity. It was found that with Cl2+or SO 4 2− being an anion, Na +, K, Mg and Ca2+ cations had a different effect on pulp viscosity and copper flotation. At the same salt concentration, divalent cations, Mg2+ and
evaluated the effect of three chemical reagent configuration on selective flotation in low and high pyritic copper sulphide ores. They showed that the collector of isopropylnethyl thionocarbamate creates the highest copper grade and the lowest iron recovery (Hassanzadeh and Hasanzadeh, 2016).
