Copper Nickel Flotation - 911 Metallurgist

15/06/2017  Cyclic Copper Nickel Flotation Tests. To further clarify the flotation response of the shaft sample, several cyclic tests were carried out. A 6-min grind in the laboratory ball mill was selected for these tests, and the result was a 40-pct minus 325-mesh grind. The flotation procedure used was to condition 600 grams of ground ore pulp for 3 min, using collector at the rate of 0.1 lb/ton; add 1 drop

Some factors that affect beneficiation of sulphide nickel ...

01/06/2007  The results confirm that the flotation results depend essentially on the grinding method in the flotation of Ni–Cu ores.3. ConclusionsIt is obvious that there are still many unknown reactions and processes in nickel separation, and in sulphide flotation generally. They include the interaction of ions and process iron, for example. Viscosity effects are also an interesting field. They may depend both

Effect of some process variables on flotability of sulfide ...

01/06/2002  After using steel mill in grinding, nickel was floated selectively with xanthate in the beginning of flotation but gradually, also pyrrhotite started to float decreasing the selectivity of separation. This was concluded to be a consequence of the galvanic interaction between small iron particles from the steel mill and sulfide particles. The iron particles obviously reduced redox potential on pyrrhotite particles impairing xanthate adsorption. During flotation,
