Nickel And Copper Flotation

Copper Nickel Flotation

Initial Copper Nickel Flotation Results Some of the results of the first pilot test on the shaft sample fell short of the values projected from the laboratory results. Copper recoveries, in particular, were low, averaging 81 pct over the 5-day test.

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.

Flotation of Nickel-Copper Sulphide Ore: Optimisation of ...

All the flotation test-work was done using the Denver laboratory machine with a 1.5l stainless steel flotation cell. The required mass of nickel-copper sulphide ore material ground to 70% passing 75 µm was weighed and placed in the flotation cell. This was followed by the addition of distilled water to about

Depressants and dispersants

A specialty depressant for pyrite gangue, sphalerite and pyrrhotite in lead and copper flotation systems. Diethylenetriamine (DETA) DETA is a polyamine used as a depressant for pyrrhotite and arsenides in copper and nickel mineral flotation.

Froth flotation - Wikipedia

Froth flotation cells to concentrate copper and nickel sulfide minerals, Falconbridge, Ontario. Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity. Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and ...

Nickel Ore Mineral Processing

The mixing flotation process is to separate nickel ore in which copper has lower content than Nickel, the mixed concentrate of copper and nickel will smelt into high grade nickel directly. Mixing-preferably Flotation Process: Copper nickel can be get from raw ore, then the copper concentrate with low grade nickel and the nickel concentrate with low grade copper can be separate from the mixing concentrate, the nickel …

Nickel and Cobalt | Solvay

Solvay offers a variety of unique solutions for nickel and cobalt processing. Flotation. Flotation reagents from our AERO®, AEROFLOAT® and OREPREP® brands enable the recovery of sulfide nickel/cobalt minerals from ore. AERO polymeric depressants, such as AERO 7261A, help in making a clean separation by depressing non-value sulfide minerals.

Copper extraction - Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

A process for beneficiating a finely ground ore containing sulfide minerals of copper and nickel by selective flotation to produce a copper concentrate and a copper-nickel concentrate comprises...

Nickel processing - Extraction and refining |

In cases such as the Sudbury deposit, where the copper content of the ore is almost equal to that of nickel, the concentrate is subjected to a second selective flotation whereby the copper is floated to produce a low-nickel copper concentrate and a separate nickel concentrate, each to be processed in its respective smelting line.

Development of a Combined Flotation and High Pressure ...

Flotation behavior of copper and nickel from mine tailing was investigated un- der varying concentrations of PAX ranging from 0 g/t to 200 g/t when other flo- tation parameters were fixed at 200 g/t of MIBC concentration, 50 g/t of pulp
