 · Both the primary and secondary copper sulphides, together with associated precious metals such as gold, are recovered from raw ores by froth flotation, a separation process based on exploiting differences in surface properties to effect separation between valuable and gangue minerals.

Introduction To Mineral Processing Chevron Phillips. Introduction to Mineral Processing The process of froth flotation entails crushing and grinding the ore to a fine size This fine grinding separates the individual mineral particles from the waste rock and other mineral particles Chemicals referred to as depressants are added to the pulp to reduce the flotation of the …

 · 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. The objective of this study was to investigate optimum grind of a blended copper ore comprising sulphide and oxide ...

 · Moreover, the flotation kinetic model of copper slag was established and the results showed that the movement of copper slag in the flotation process conforms to the first-order kinetics. The addition of sodium carbonate increased the stability of the pulp and improved the flotation kinetics greatly, resulting in a better flotation performance.

 · This model was the basis for the optimization of effects of copper ore flotation processes preceded in high-pressure crushing operation in roller presses. View Show abstract

 · In general, the model predicts that the recovery of both copper and iron increases as grinding and flotation times increase (Fig. 7). Moreover, the kinetic constant values are in agreement with their definitions—that is, medium–fast species have higher values than the other species, and the coarse–slow species are the slowest.

A complete flow diagram including crushing, grinding, density media separation, froth flotation, pyrometallurgical, and hydrometallurgical process route to achieve highest purity of metals. The nickel–copper-dominated sulfide concentrate is recovered through the extractive pyrometallurgical-process route by conventional roasting and reduction ...

 · However, recovery of copper was about 4 percent lower for the high copper slag (sample C) and 23 percent lower for the low copper slag (sample A). Flotation tailings …

 · For the LJ ore, wet grinding without lime-addition in the mill led to somewhat poorer flotation performance than dry grinding or wet grinding with lime-addition in the …

 · Following primary/secondary crushing, the material is processed through a rod/ball mill grinding circuit ahead of rougher/scavenger flotation that produces a copper concentrate.

 · Sulfidation flotation method is mainly used to treat oxide copper minerals, mainly copper carbonates, such as malachite, azurite and other minerals, or cuprite, but special treatment is required for silicic malachite, otherwise the sulfide Not very effective, not even vulcanizing. l Hydrothermal Vulcanization Flotation Process
