    Mineral Flotation

     · As most copper orebodies exhibit an insitu grade of less than 1% Cu, the mass pull to the rougher froth is often low. This means that the throughput of the cleaner stage is significantly less than the throughput of the rougher stage which imparts a relatively low capital and operating cost to the flotation circuit. "To counteract the possible absence of a scavenger stage, a slightly higher ...

    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 ...

    In general, a decrease of ore grades can be discerned, whether the mine has a high initial copper ore grade, such as NevesCorvo (Portugal) or Mount Isa (Australia), or a lower copper ore grade, such as Aguablanca (Spain), Telfer (Australia) or El Tesoro (Chile). For example, El Soldado copper mine (Chile) had an average oxide ore grade in 2003 of % and in 2012 the average ore grade was ...

    Copper oxide ore has a complex composition, and a low recovery rate is often achieved via the traditional sorting method. A new combined process of flotation–highgradient magnetic separation–leaching is proposed here to recover copper minerals. The test results showed that the flotation process was successful when using sodium sulfide as a vulcanizing agent and butyl xanthate as a collector.
