flotation copper electrolytes

2015/11/10Flotation of inherently hydrophobic minerals in concentrated solutions of electrolytes does not require the use of any other reagents. In Klassen's publications this is referred to as "salt flotation" ( Klassen and Mokrousov, 1963 ). The major constituents of the Inco matte, chalcocite (Cu2S) and heazlewoodite (Ni3S2), are separated by differential flotation with diphenylguanidine as collector. To select an effective organic depressant, many dextrins were tested and tapioca dextrin 12 was found to have an exceptional affinity towards heazlewoodite surface at a particular pH of the mineral suspension. A new reagent system

1986/5/1Precipitate flotation was carried out in a multibubble apparatus. This is a glass column 100 cm3 in volume and 25 cm high, with a G-3 sinter at its bot- tom. The flotation process was conducted for 10 min at a constant flow rate of nitrogen equal to 25 cm3/min.

2012/4/15The copper foam electrode exhibits high TCE elimination efficiency in a wide range of initial TCE concentration. Under coulostatic conditions, the optimal conditions to achieve the highest FEE are 9.525 mm thick copper foam electrode, 40 mA current and 0.042

The copper(I) chloride and bromide salts are produced by boiling an acidic solution of copper(II) ions in an excess of copper. On dilution, the white CuCl or the pale yellow CuBr is produced. Addition of soluble iodide to an aqueous solution of copper(II) ions results in the formation of a copper(I) iodide precipitate, which rapidly decomposes to Cu(I) and iodine.

2014/11/1A copper ore sample obtained from an Australian copper plant was crushed to a size of −1.70 mm and stored in a freezer before grinding and flotation. The copper grade of the ore is about 2.9%. Quantitative XRD analysis indicates that the copper ore contains 0.1% chalcopyrite, 0.4% cuprite, 4.7% chalcocite, 40.6% hematite, 16.4% muscovite, 33.8% quartz.

Tests made on numerous individual determinations showed that the electrolytes contained 0.0092 per cent, of the original copper. Table I shows, on the other hand, that the copper which is deposited is not entirely pure, that in this case it contained 0.0093 per cent, of its

yttrium ore flotation

The copper oxide ore in Dali, which contains 0.69% of copper and 11.24g/t of silver, was beneficiated by sulphidizing xanthate flotation method. The flotation tests were carried out systematically with sodium sulfide as sulphidizing agent and butyl xanthate ammonium dibutyl

The fine fractions were further ground and used for zeta potential measurements. The high purity sodium dodecylsulfate (SDS) purchased from Fluka were used in flotation studies. The pH was adjusted by HCl and NaOH. The inorganic electrolytes, NaCl, CaCl2
