The simplest grinding circuit consists of a ball or rod mill in closed circuit with a classifier; the flow sheet is shown in Fig. 25 and the actual layout in Fig. 9. This single-stage circuit is chiefly employed for coarse grinding when a product finer than 65 mesh is not required, but it can be adapted for fine grinding by substituting a bowl ...

At Chuquicamata columns are used in the molybdenum circuit. The bulk copper- moly concentrate is thickened and fed to the Cu/Mo separation circuit that is schematically shown in Figure …
Moly flotation circuit. Copper and moly are often found together as sulfides, which in solution will float or sink with the right combination of chemicals and gas bubbles (froth …
SAG Mill Circuit Example — Gold Processing SAG mill circuit example for gold processing [image: (135-6-3)] AG/SAG Mill. AG/SAG mills are normally used to grind run-off-mine ore or primary crusher product. Wet grinding in an AG/SAG mill is accomplished in a slurry of 50 to 80 percent solids. 2D and 3D simulations of particles in a SAG Mill
Whichever reagent is used, it is better to introduce it into the cleaning circuit if possible, because any excess entering the machine through occasional faulty control is likely to cause a lower gold loss there than in the roughing circuit. The addition of copper sulphate up to 0.25 lb. per ton is sometimes found useful in speeding up flotation.

Year-to-date the Pinto Valley mine, leach operation and mill have produced 96.2 million lb. of copper. This year's guidance for both the Pinto Valley and Cozamin mine in Mexico is 175 million to ...
The grinding circuit includes a semi-autogenous ball milling-crushing circuit containing a SAG mill and two fixed speed ball mills. The processed ore is then sent to the 28Mt/y concentrator plant containing a copper and molybdenum flotation circuit. Ore processing. The crushed ore is treated with slaked line in the copper floatation circuit. It ...
Copper is a relatively soft and malleable metal with excel-lent formability, making it ideal for architectural applica-tions such as roofs, wall cladding, gutters and downspouts. Additions of other elements to copper strengthen it and form copper alloys, including brasses, phosphor bronzes and copper nickels.
circuits flow by gravity to tailings thickeners for water recov ery prior to disposal. The Toquepala concentrator has facilities for processing the copper-moly concentrate to produce a moly concentrate for shipment (MoS2). The tailings from the moly plant (copper concentrate) is dewatered in a filter plant and then transported
The residual floc in process water going back to the milling circuit will have negligible impact. The amount of floc is small in comparison with the tonnage of solids and the milling circuit will destroy whatever floc comes through. ... As mentioned, in order to ignore floc impact on Moly flotation, it is a common practice to design copper-moly ...
1. Introduction. Copper-molybdenum flotation plants usually implement two sequential circuits to produce copper and molybdenum concentrates. In the first circuit, copper and molybdenum minerals are recovered as a bulk concentrate, while in the second circuit, copper sulphides are separated from molybdenite (Amelunxen and Amelunxen, 2009).In …
4. Bulk (Copper-Moly) Thickener. A high-rate thickener dewaters the bulk of copper-moly concentrate before more separation. 5. Moly Flotation. The moly flotation circuit has similar groups of flotation cells with chemicals to float the molybdenite (moly concentrate), and settle out the copper sulfides (copper concentrate). 6. Copper Thickening ...

Molybdenum will float naturally with the copper but can be crowded in the froth by the copper mineralisation and use of a moly collector (such as diesel oil, kerosene, refined oils, pine oil or xanthate ester) enhances its floatability. Further, because optimum moly flotation pH is at 7-8 while optimum copper selectivity is typically in the 9 ...
