Foam flotation is a process by which collectors condition a mixture of water (suspension) to make the copper minerals water repellent while leaving the non-Cu minerals hydrophilic.Flotation is made from finely ground copper ore in flotation cells.The previous page explains the types of copper ore that exist and the extraction process that results in finely ground copper ores.
Once the ore has been ground and a size distribution of particles is presented to a flotation cell, the only parameter that can be manipulated to reduce the entrainment is water recovery. If additional water is added to dilute the contents of the flotation cell, and the flow rate of water to the concentrate remains the same, the water recovery will

Mar 01, 2009· Flotation response for copper oxide composite using AM28 as the copper collector. Total AM28 and MIBC doses for both Tests A and B were 1200 g/t and 50 g/t, respectively. Download : Download full-size image; Fig. 5. Copper grade–recovery relationship from the rougher scavenger flotation test for the copper oxide composite.Cited by: 184
The aim of this study was the recovery of copper from the oxide copper ore by froth flotation and agitating sulphuric acid (H 2 SO 4) leaching. The ore with 4.21% copper grade used in this study was obtained from Çorum-Dangaz region of Turkey. Native copper, cuprite (Cu 2 O), tenorite (CuO), and malachite (Cu 2 (OH) 2 /CO 3) were the文件大小: 2MB
Further reagents (collectors) are added to the flotation cells 3, 5 and 9. The collector distribution pattern is 32% for ball mill feed, 32% for the third rougher flotation cell, 20% for the fifth rougher flotation cell and 16% for the ninth rougher flotation cell. Tailings from the last rougher flotation bank
Calculate the required cell volume and dimensions of the cells. Explain the criteria of your selection. The specific gravity of the ore is 4 g/cm3.

flotation of copper-nickel and copper-molybdenum ores is known to have positive effects . The other advantage of PTTC and OPDTC is that these reagents may be prepared and added into flotation cell as individual compounds or incorporated into modified collector solutions composed of xanthate
Mar 01, 2018· The flotation tests were performed under different conditions, in a mechanical cell and a column cell, to understand the influence of cell type and shear on flotation recoveries. The current work also examines the effect of preconditioning and flotation temperature on mineral recoveries, to demonstrate the thermo-switchable collector/depressant
Dec 01, 1997· Process. 52 (1997) 8 I- 120 considered that in practice the hydroxide-coated surfaces may well convert to sulphide within a few minutes, and pointed out that, under the abrasive conditions of practical flotation, the copper-hydroxy coatings might be removed, exposing the underlying copper sulphide surface.
