Improving the Flotation Circuit Performance onemine . Jan 01 2018· Froth flotation is used to produce nickel and copper concentrates. As is the case at other operations the presence of magnesium is detrimental to the flotation products. In the past year the exploitation of a new deposit has increased magnesium in the feed. Thus it

Copper Nickel Flotation

Batch Copper Nickel Flotation Tests. Testing of the shaft sample was conducted with sodium isopropyl xanthate collector throughout the laboratory test series. The change from isobutyl zanthate (which was used with the pit sample) to isopropyl zanthate was for convenience only and had little or no effect on the flotation results. Methyl isobutyl

Improving the Flotation Circuit Performance Using

Figure 1 shows the location of the mine site. After crushing and grinding froth flotation is used to produce nickel and copper concentrates. The flotation circuit is designed with multiple stages consisting of bulk copper/nickel flotation copper/nickel separation and a separate nickel circuit (bulk float and cleaning)."

The effect of chemical reagents on flotation performance

Nickel ores that have a high pyrite content can be floated by reverse flotation in which pyrite reports to the concentrate and pentlandite to the tailings stream. This is because nickel is easily depressed at a pH above 9.5 enabling the pyrite to be selectively floated under alkaline conditions.
