Copper Ore Crushing, Grinding & Flotation

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

Grinding and Concentration of Conglomerate Copper Ore

The conglomerate ore analyzed approximately 1.2% copper. The specific gravity of the ore was 2.72 and the bulk density was 108 pounds per cubic foot (determined on “as is” ore). The Bond laboratory ball mill work index was determined as 22.0 at 65 mesh. Autogenous Grinding Tests Crude ore was fed manually to the mill, wet ground, and discharged through slotted grates and five pebble slots

Copper Ore Processing Methods

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger

The influence of copper ore lithology on the grinding

Oct 15, 2014· The main aim of laboratory tests was to find a relation between lithology of tested samples of ore and grinding media wear. Wear tests were performed in a laboratory mill filled with ball grinding media. Wet grinding was performed, which is typical for copper ore milling. Details of equipment used and tests data are presented Table 3.

Grinding Kinetics Adjustment of Copper Ore Grinding in an

Copper ore with a particle size between 0–1 mm was used in the experiments. A model was created that determines the relationship between the processing time and efficiency of the grinding, and can be used for the optimization of the process. A comparison of the relative growth of particle size fractions in milling products was performed.

A review of the effects of the grinding environment on the

Jul 08, 2011· Bruce (1976) found that, in pilot plant studies with a Cu–Zn ore, autogenous grinding yielded improved copper (and zinc) recoveries compared with grinding in a mild steel environment albeit that the copper and zinc grades were slightly lower. Fahlstrom, 1974, Fahlstrom et al., 1975 reported on a plant study at Boliden's Aitik copper mill in

Copper Ore Grinding Process In Malaysia

Copper Ore Grinding Process In Malaysia. The next step is to feed the crushed ore into a wet grinding process in tumbling mills. These mills contain the ore, water and steel balls and further reduce the particles to the optimum size for the flotation process which follows. About 80 of copper from ore is generated using flotation, smelting and

Effect of microwave pretreatment on grinding and flotation

The present work initially studies the kinetics of microwave-assisted grinding and flotation in a porphyry copper deposit. The kinetics tests were carried out on the untreated and microwave irradiated samples by varying the exposure time from 15-150 sec. Optical microscopy, energy-dispersive X-ray spectroscopy and scanning electron microscopy were used for determining the mineral liberation

Copper Ore an overview ScienceDirect Topics

The copper ore production process operation as defined in Section 3.1 is simulated for a period of one year with various failure modes. The time evolution of the cumulative cost curves and copper output for 100 Monte Carlo (MC) simulations are shown in Figure 5 for easier visualisation. More MC simulations can be done while characterising the system.

Copper extraction Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).
