Copper Flotation Metallurgist & Mineral Processing

16-05-2016· Flotation of Copper Ores In most plants engaged in the flotation of ores containing copper-bearing sulphide minerals with or without pyrite, pine oil is employed as a frother with one of the xanthates or aerofloat reagents or a combination of two or more of them as the promoter.

60 Centuries of Copper: The Flotation Process

The powdered product of grinding the ore is fed into a series of tanks called flotation cells which are filled with a solution containing various oils capable of forming a froth. Air is pumped into each cell, the solution being agitated to bring froth of bubbles to the surface.

13-04-2016· Copper Sulfide Flotation Circuit The pulp from the Conditioner is treated in a 10-cell “Sub-A” Flotation Machine and a 4-cell “Sub-A” Flotation machine. Sometimes conditioners are not provided; however, their use insures that reagents are thoroughly mixed into the pulp ahead of flotation.

Separating Minerals by Floatation ABB

ore slurries tend to be acidic. Plants typically add lime to the slurry in the mill or floatation circuit, increasing its alkalinity. A typical copper operation contains many floatation cells, often with a pH sensor in each cell. The number of sensors and their locations vary from plant to plant, being largely dependent on solution chemistry. Sensor life and maintenance quickly becomes important economic factors. The pH sensor in any mineral processing

Development of copper recovery process from flotation

15-06-2018· The total copper recovered from its ore through flotation process is about 56% [ 6, 18 ], which indicates that the flotation tailings still contain valuable copper components such as chalcopyrite. In addition, old flotation tailings sometimes have a higher copper grade (0.2–0.4%) than that of low‒grade ores (0.2‒0.3%).

Hellyer ore contains finely disseminated chalcopyrite, sphalerite, galena, and tetrahedrite. The flotation plant design was based on extensive benchscale testwork (including locked cycle tests) on drill core and many months of operation of a 30 tonne per hour “pilot plant” using the old Cleveland Tin Mine process plant, modified for the duty.

Crushing plant product is then conveyed 1.4 kilometres to fill any one of six fine ore bins, each one feeding six rod mill flotation sections, all operating in parallel. Certain sections are used for wet grinding marginal ore to below 0.3mm, followed by a copper flotation process similar to that used for the underground ore.

Jameson cell Wikipedia

The high intensity of the Jameson Cell means that it is much shorter than conventional column flotation cells (see Figure 1), and it does not require air compressors to aerate the suspension of ground ore particles and water (known as a slurry or pulp) in the flotation cell. The lack of a requirement for compressed air and the lack of moving parts means that power consumption is less than for
