Copper Nickel Flotation - 911metallurgist.com
The Bureau of Mines investigated the flotation responses of two copper nickel ore samples from the Duluth Complex with the objective of recovering bulk sulfide concentrates. One of the ores studied was taken from a test pit; the other was taken from a test shaft. The samples were quite similar except that the pit sample analyzed 0.35 pct Cu and 0.11 pct Ni and the shaft sample analyzed 0.69 ...
Copper-Nickel ores - Danafloat
Some plants use bulk flotation in an acid pH environment which is achieved using SO2 or H2SO4. Separation of the bulk concentrate copper and nickel minerals is generally accomplished by flotation of the copper from pentlandite and nickel-bearing iron sulphides which report to the flotation tails. Pentlandite and iron sulphides are depressed by raising the pH up to 12 with lime and a small ...

The easily Soatable non-sulRde min-erals dilute the grade of the concentrate and also result in nickel losses into the tailings. This problem can be overcome by using depressants like car ...

With a flow sheet that uses bulk copper–lead flotation followed by copper–lead separation, the gold recovery is higher than that achieved with a sequential copper–lead flotation flow sheet. In laboratory tests, an aerophine collector type, in combination with xanthate, had a positive effect on ...
Copper-Cobalt ores
Bulk flotation sequence: Under the bulk flotation process, a bulk Cu-Co flotation concentrate is produced at natural pH with xanthate, dithiophosphate and/or MBT, particularly if the copper mineralization is chalcocite. Copper is separated from the cobalt in the bulk concentrate by raising the pH up to at least 11 which depresses the cobalt minerals. Cobalt depression can be enhanced by small ...

Effect of PAX provided an overall effective bulk flotation as grades of 1.56 wt% and 0.75 wt%, and recoveries of 84.73% and 25% Cu and Ni were observed re-spectively. It has been observed that Ni recovery wassubstantially low er than copper recovery; this is particularly due to the presence of non-sulphide Ni in the ore and also lower floatability of pentlandite. Copper recoveries were favored ...

Flotation kinetics of pentlandite and violarite contained in copper–nickel ores and the effect of crystallochemical peculiarities of the minerals on their flotation features are studied. Studies of the effect of pentlandite crystallochemical features on its flotation properties have shown that the easiest to float is nickel-enriched pentladite, cobalt-enriched one being somewhat worse the ...
