Both samples were final flotation products from the respective copper flotation circuits and were taken before entering the molybdenum circuit. The Morenci copper/molybdenum concentrate analyzed 0.2%-0.4% Mo and 28%-33% Cu, while the grade of the Copperton copper/molybdenum concentrate was 2.5%-4.1 % Mo and 32%-34% Cu. The concentrates were
This report provides a perspective on the amount of water used by a conventional copper flotation plant, including the makeup water required to compensate for water losses. Much of the global supply of copper originates from mines that also produce byproduct molybdenum, but for simplicity, a single copper concentrate has been modeled for this ...
The effects of Z11 and AP407 collectors as well as AF65 and AF70 frothers were evaluated in the rougher flotation circuit of the Sungun copper concentrator plant using 2 4 full factorial design. Response functions were produced for both Cu grade and recovery and optimized within the experimental range.

Froth flotation is widely used for concentration of base metal sulphide minerals in complex ores. One of the major challenges faced by flotation of these ores is the ever varying grade and mineralogy. This therefore calls for a continual characterisation and optimisation of flotation parameters such that concentrator performance as a whole is always maintained. In this …

OXIDE COPPER CIRCUIT— The tailings from the sulphide copper flotation circuit are pumped through 10″ x 8″ DRL Pumps to a 10-way splitter box where it ... The high grade concentrate is thickened and filtered in the high grade oxide copper thickeners at the concentrator plant prior to transfer to the leach plant for electrowinning of copper ...
The intercept is zero, because the adjustment led to the regression line passing through the zero value. It must be borne in mind that, although we study a specific flotation process for copper ores, its oxidized degree can vary within a range. Therefore, the range of copper grades in the feed was also chosen as independent variables for its study.
The Jameson Cell is a high intensity flotation device, which utilises induced air from the atmosphere. It was developed jointly by Mount Isa Mines and Professor Graeme Jameson of the University of ...
Forty-eight batch rougher flotation experiments (pH 11.5) for Miduk porphyry copper ore consisting of 0.9% Cu were conducted at different conditions using a bench scale Denver flotation cell with 3 L capacity. Second order response functions were generated for both the Cu grade and recovery models, as metallurgical indicators.
Rosebery copper concentrator. The Rosebery comminution circuit has three stages of crushing followed by two stages of closed circuit grinding, utilising mild steel grinding media. Classified slurry from the grinding circuit is dewatered in a flotation feed thickener from where feeds a three stage copper–lead–zinc sequential flotation ...
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, …
An example solving a copper concentrator flotation circuit is presented. This method is simple and easy to make from simple to a complex froth flotation circuit.: Solid specific gravity from the ...
Typically, rougher molybdenite flotation and recovery from bulk copper/molybdenum concentrates involves the use of alkalisulfides, Nokes reagents, cyanides, oxidants, and/or thermal treatment to depress copper sulfide minerals. The bulk copper/molybdenum feed generally varies from 0.2% Mo to 1.0% Mo, and with traditional …
rigidity of bubbles in the flotation column. The effect of particle size on a flotation process in the Barrick Oborn copper concentrator was studied by Crosbie et al. The study showed that the efficiency of the flotation process is maximized when the particles' size range from ultrafine (1CS5) to 53µm and considerably low outside the
Pyrite depression in the flotation of copper ores is difficult due to the activation of Cu2+ ions on pyrite surface. In this study, the radical chain reaction involving the redox cycling of Cu(I/II) induced by sodium metabisulphite (MBS) was exploited to selectively depress the flotation of copper-activated pyrite at pH 8.0. Electrochemical measurements revealed that …
North Concentrator commenced functioning in 1972 and subsequently underwent expansion through continual minor projects. South Concentrator began functioning in 1991.
