Copper Nickel Flotation

2017-6-15  Copper Nickel Pilot Plant Flotation Pilot plant flotation tests for both the pit sample and the shaft sample were done in the Bureau’s TCRC flotation process demonstration plant. Both samples were tested using flotation circuits that consisted of a rougher float followed by three cleaner floats, plus a scavenger float

Copper-Nickel ores - Danafloat

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

Use of Ozone in the Differential Flotation of Bulk Copper ...

Differential flotation of bulk sulfide concentrates from Duluth gabbro into copper and nickel concentrates could be implemented by first destroying the hydrophobic coating with ozone and then by recovering the copper concentrate with a copper-selective collector. A number of parameters involved in the use of ozone, such as the sequence and the conditioning time of ozone treatment, the pulp pH ...

NICKEL AND COBALT ORES: FLOTATION

2016-6-7  A typical example of a nickel sulRde plant operat-ing with highly Soatable talcose gangue is at Trojan mineinZimbabwe.TheZimbabweansulRdedeposits contain very low grades of nickel (0.6%) and copper (0.04}0.4%). The easily Soatable non-sulRde min-erals dilute the grade of the concentrate and also result in nickel losses into the tailings. This ...

PLATSOLTM TREATMENT OF THE NORTHMET COPPER

It is well known that high temperature pressure oxidation (T ³200ºC) could dissolve copper and nickel. The fundamental difference between the PLATSOLTM process and conventional high temperature pressure oxidation is the addition of chloride ions to theautoclave feed. It was discovered that the addition of chloride at concentrations as low as ~3 g/L (5 g/L NaCl) resulted in the dissolution of most of the PGM’s in the autoclave together with copper and nickel. The PGM’s were easily recovered by NaHS precipitation while copper and nickel
