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 amount of sodium cyanide. Elevating the slurry temperature to 30-35 degrees C may improve the separation. Addition of depressants, such as starch or dextrin, may improve pentlandite
