New flotation reagents for sulphide nickel minerals flotation. Flotation studies on a nickel ore containing 4–5% pentlandite, 4–5% chalcopyrite and 30–35% pyrrhotite with seven synthesized N-arylhydroxamic acids revealed that N-phynylacetyl-N-(2,6- dimethylphenyl) hydroxylamine (PANXHA) was observed to have the highest first order rate constant and highest selectivity index for ...
Copper Nickel Flotation
Laboratory Copper Nickel Ore Flotation Pit Sample Procedure. Testing of the pit sample indicated that a 90-pct minus 200-mesh grind would result in adequate liberation of the sulfide minerals. Grinding was carried out in a laboratory rod mill at 60 pct solids, and flotation was carried out in a standard laboratory flotation cell at about 30 pct solids. Various xanthate collectors were evaluated at addition levels of …

Sulfide ores are crushed and ground in order to liberate nickel minerals from the waste materials by selective flotation. In this process, the ore is mixed with special reagents and agitated by mechanical and pneumatic devices that produce air bubbles. As these rise through the mixture, the sulfide particles adhere to their surfaces and are collected as a concentrate containing 6 to 12 percent ...

Sulfide Ores - an overview | ScienceDirect Topics
The universal technique for this concentration is froth flotation of finely ground ore. Froth flotation entails attaching fine Cu-sulfide mineral particles to bubbles and floating them out of a water–ore mixture. The flotation is made selective by using reagents, which make the Cu-sulfide minerals water-repellant (hydrophobic) while leaving the other minerals wetted (hydrophilic).

Copper- Nickel Ore Flotation Process. When process copper-sulfide nickel ore, collector and frother will be used in order to better results. A basic principle of copper-sulfide nickel ore process is that it is better to let copper assimilate into nickel ore rather than the opposite. For it is easier to recovery cooper from nickel concentrate. The process has a vital advantage-receive copper ...
