Bulk flotation vs. Selective flotation - Froth

For Copper and Lead flotation: We need to float both minerals 1st. We call it Bulk flotation. Then this bulk concentrate will go to Cleaning stage where we depress Copper, and float Lead-This process we call selective flotation. Case study-2. For Zinc and Lead Flotation. Here we depress Zinc and float Lead-This is called selective flotation

Method of flotation enrichment of sulphidic

There is a method of enrichment of sulphide copper-Nickel ores, comprising grinding the original ore to a particle size of 45-50% of the content of the class less than 0.071 mm in the presence of butyl xanthate, introduction to the pulp of the expander T-80 and subsequent flotation with the release of sulfides of copper and Nickel in the bulk concentrate and non-metallic minerals in final

flotation copper nickel - vokastages.be

Separation of the bulk concentrate copper and nickel minerals is generally accomplished by flotation of the copper from pentlandite and nickelbearing 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.

Sulfide Ores - an overview | ScienceDirect Topics

Nickel sulfide ores contain pentlandite, (Ni,Fe) 9 S 8, and chalcopyrite, CuFeS 2. These minerals are always recovered together in a metal-rich bulk concentrate by the following steps: (a) crushing/grinding; and, (b) froth flotation of the ground pentlandite and chalcopyrite particles at pH ~9, which separates them from the pyrrhotite and gangue rock particles in the ore. This bulk
