coarse grind copper ore

  • Increasing the grind size for effective liberation and

    1/8/2016· For the porphyry copper ore tested in these investigations, a coarse copper sulphide grain size coupled with a high association with hard microwave-transparent (i.e. quartz) and hard microwave-heating (i.e. pyrite) minerals resulted in a grind size increase of 50–60 μm for equivalent liberation or an approximate 2.5% increase in liberation at an equivalent grind size.

  • Improving the recovery of low grade coarse composite

    1/7/2011· The copper recovery in rougher and coarse scavenger stages for ORE 1 and ORE 2 is presented in Table 1, Table 2, respectively.The total copper recovery for ORE 1 at the standard grind size (d 80 = 150 μm) was approximately 90%.This value decreased to about 77% and 73% at coarser grind sizes of 250 μm and 320 μm, respectively.

  • Grind Optimization of Konkola Blended Copper Ore

    1/8/2020· Konkola West Concentrator stockpile handles 55000 tonnes copper ore per day producing an average of 400 tonnes of concentrate. The grade of the concentrate is 36 to 40% TCu. The plant efficiency (recovery) is at 89% TCu. The concentrator operations include: Primary, secondary and tertiary crushing, grinding, flotation, dewatering and tailings disposal.

    porphyry copper ore at the nominal plant grind size and a coarser grind size at the coarse end of the normal flotation range after high power density microwave treatment. The relationship with mineralogical textural features is also elucidated to understand the interaction of microwave treatment with the ore and its effect on selective breakage leading to improved liberation and flotation. 2

    Crushing and Grinding You will note that the Oracle Ridge project has utilized a two-stage crushing circuit with a double acting jaw crusher and cone crusher. In order to utilize this system, the jaw crusher is oversized to produce all -5 material for the cone mill with a screen in closed circuit. Normally a three-stage crushing circuit would have been more conventional, but with the type of

    Ore is transported to the above ground Coarse Ore Storage Area (COSA) by low-profile, 45-ton loaders. Inside the COSA, a front-end loader will fill road haul trucks with ore on average 18-24 inches in size. Truckloads are covered before passing through the truck wash and continuing off-site to travel approximately 66 miles to the Humboldt Mill. Eagle will be mined from the bottom –up and
