The products includes five series: crusher, sand making machine, powder grinding mill, mineral processing equipment and building materials equipment.copper plant regrinding mill circuit flow sheet,This occurs at a mill facilitywhich is known as a concentrator. The ore from the mine (averages 0.25% to 0.50% copper) is initially reduced in size to about 10 to 0.5-inches by a one or more stages of crushing. The crushed ore reports to a grinding circuitwhere steel balls are used to further reduce it to a consistency of a fine beach sand..

Sulphide copper-gold ores are usually sorted by flotation.
Swiss Tower Mills Minerals AG develops fine and ultra-fine grinding mill productsusing an innovative technology. A range of services is available from consultingconceptual and detail engineering to productionsite assembly and lifecycle service support.
Dec 172020 Elements such as copper can be measured to a precision of 0.02% copper over thirty seconds which is sufficient for high confidence in decisions for bulk flow diversion. Increments of 8 tons (from a 1,000-ton-per-hour flow) are diverted through a bulk ore sorting application to remove batches of waste from mill feed as well as divert material
the number of flow sheet configurations. In addition some streams (e.g.streams between cleaner and scavenger subsystems) can be eliminated as needed. Fig. 2 shows the first and second level superstructures. In each stage two kinds of cells are allowedbank and column flotation cells. Also the regrind mill is incorporated for some streams.
The plant employs a semi-autogenous SABC-A grinding circuit comprising of a primary SAG mill and pebble crushing followed by a Antapaccays flow sheet is shown in Figure 1 below. Figure 2 shows the copper concentrator photographed after commissioning. Improve process stability and maintain constant flow to the flotation plant time CV MV
grinding chamber and allowing it to flow into collection bags or a transfer hopper for reuse. Open-circuit configuration Because it has multiple grinding stages in a single unitthe HIGmill operates in an open-circuit configuration and without recirculating loads. A pre-scalping cyclone prior to the mill can remove the fines from the feed so
The HIGmill comprises a mill bodyshaft with grinding discsshell mounted counter ringsgearboxand drive. The grinding chamber is filled up to 70% with grinding beads. Rotating discs stir the charge and grinding takes place between beads by attrition. The number of discs (grinding stages) depends on the application and can be as high as 20.
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 plantmodified for the duty. The Cadia concentrator was designed on an extensive benchscale variability testwork

new plantsuch data are much more difficult to come byparticularly if the ore is from a deep underground mine. In this casethe most appropriate approach is to use experimental data obtained from a similar pulp on a currently operating plant.

Most copper ores contain 1% copper and most of the energy and reagents used to extract that copper are consumed by the gangue minerals. Considering thisit is critically important in any copper project to understand both the ore and the gangue mineralogy before developing or optimising the process circuit.
Slurry from the grinding circuitat approximately 35% solids and 8085% passing 135 mm is pumped to three thickeners. Thickener underflowat approximately 54% ww solidsis pumped to a train of four acidulation tanks. Sulfuric acid is added to the slurry to destroy sufficient carbonate prior to entering the autoclave circuit. Process air is also injected into the acidulation tanks to aid
