Copper Ore Grinding. Porphyry copper ores usually are medium to medium hard and require grinding to about 65 mesh to economically liberate the copper minerals from the siliceous gangue. Sometimes a regrinding circuit is advantageous on the rougher concentrate and on the scavenger concentrate.
the copper mineralogy remaining diverse and varying from native, oxide, secondary, and primary copper species within short time periods. The development of the Phu Kham fl ow sheet was driven by the poor recovery in comparison to other lowgrade coppergold ores, and a need to counter decreasing ore grades from 2013.
However, the ability to exploit microwaveinduced fracture by improving flotation recovery and grade, and/or increasing the primary grind size to effect liberation has significant potential benefits in terms of increasing plant throughput and metal production while reducing metal specific energy consumption, even without significant reductions in ore competency.
Mine development plan increases processing capacity to 85,000 t/d Project Gibraltar Copper Mine. ... The project incorporated additional primary grinding, secondary grinding, regrind, rougher flotation, cleaner flotation, concentrate filtration and tailings pumping capacity as well as various ancillary systems and upgrades. ...
An example of a copper metallurgy study where the effect of primary grind on rougher flotation each of the GeoMetallurgical samples was investigated. A simple economic study was conducted on these copper flotation results, using typical power costs and a net smelter revenue value for copper of 90 cents. This indicated that the optimum grind was about 140 µm to 150 µm.
The primary ore zones were comprised of more competent ore, resulting in lower grinding circuit throughputs and better copper and gold recoveries in flotation. The flow sheet selection was typical of a large copper concentrator except for the inclusion of a third stage of cleaning and the use of sand mill based regrind. The flow sheet is ...
Froth flotation is a process for selectively separating hydrophobic materials from is used in mineral processing, paper recycling and wastewater treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
Gravity Gold Rougher Concentrate Flotation CIL Leaching Refining: This mineral processing plant is to recover gold from sulphide ore deposits. Provided here are all major equipment for a plant arranged to recover gravity gold, float a gold rich sulphide concentrate, liberate the sulphide hosted gold with a light regrind and dissolved its precious metals using the CarboninLeach process.
and commissioned in November 2008. During the initial stages of sulphide operation, high copper (Cu)low zinc (Zn) ore was fed to the plant. Marketable copper concentrate at 9195% recovery was produced utilizing a highpH bulk sulphide rougher flotation and 2 cleaning stages. Because of increased levels of .
Batch rougher cleaner flotation testing has been conducted leading to recent completion of locked cycle flowsheet testing; key results are presented in Table 3; grade recovery curves are presented for copper in Figure 3 and zinc in Figure 4 based on a primary grind (P 80) size of 63μm and rougher .

In the flotation of copper ores several processing plants report that copper recovery is affected by the proportion and type of pyrite in the ore, with the effect becoming more intense when the feed ore particles are fine, in fine regrinding. In this work, a model

primary grind on the mineral liberations is shown in Figure 2C. The quality of the copper and gold bearing particles are shown in Figure 3A and 3B. The limiting grade recovery curves (See Figure 3C) suggest that a rougher concentrate, assaying 5 to 10 percent copper at the around 90 percent copper recovery, can be theoretically achieved.

82% Au by 6stage rougher flotation. Although finer grinding improved the copper recovery, primary grinding to a 80% passing size (P80) of 150μm was the indied optimum target with regarding the energy consumption in the comminution processes. The tests reveal that .
Both copper and gold values in the ore were readily recoverable by froth flotation ( 07o copper rougher recovery and *^ gold rougher recovery). However, the high concentrate weight (2607o) and low concentrate grade ( Cu and g/t Au) indicate that extensive cleaning with regrinding would be required to produce a

The present work deals with the results of investigations carried out at different stages in the grinding and flotation circuits of a plant, treating a low grade copper ore. Conventional and autogenous grinding methods are compared, to evaluate the effects of different grinding environments and consequently the pulp chemical conditions.
Hence, leaching did not improve the comminution properties of the ore. In terms of copper recovery, the flotation response of the chalcopyrite ore was also not affected by atmospheric leaching. This is apparent from the plots in Fig. 12, which compares copper recovery in rougher flotation for the ore .
Even though these minerals occur in relatively small amounts they can often be economically recovered as byproducts for the expense of mining, crushing, and grinding is absorbed in recovery of the copper. A Copper Flotation Flowsheet Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper ...
