flotation process for low grade nickel ore

201724&ensp·&enspmicrocracking on the flotation of low grade nickel sulphide ore. The ore treated contained serpentine minerals which have a history of being difficult to process efficiently. The use of oxygen as a bubbling gas has been noted to be effective because it increases the pulp potential.

Flotation of Fully Liberated Low Grade Copper-Nickel Ore

2021-3-21  Flotation was initiated by adding the chemical reagent and conditioned for 5 min, and pulp level was adjusted by adding make up water. Flotation was started by opening the air valve, and the air flow was adjusted to 4 L/min, while the copper concentrate was collected for five minutes followed by the nickel concentrate.

The enrichment depends upon the degree of rejection of the other sulRde and non-sulRde gangue. The maximum grade of nickel achieved by Sotation is around 28% Ni.

Development and implementation of a new flowsheet

2005-12-15  By comparison with conventional flotation, the flotation of coarse, low grade composites is particularly strong. Testing of a range of nickel and copper ores has shown that this improvement not only raises recovery, but also allows the primary grind to be coarsened which, in turn, increases throughput.

2017-6-15  Based on this information and the need for separate processing facilities that would be required for each concentrate if separate nickel and copper concentrates were produced, the authors decided to produce a bulk sulfide concentrate and separate the copper and nickel further along in the process flowsheet. Flotation was conducted to recover bulk sulfide

Enhanced methods for nickel recovery from low

2021-6-11  Low-grade ores, like nickel sulfide, are abundant on Earth. Nickel sulfide deposits contain high levels of magnesium silicate gangue minerals (MgO) and can be difficult to process with conventional flotation and smelting technologies. MgO is hydrophilic, which interferes with flotation of sulfide minerals, and reduces flotation

PROCESS FOR RECOVERING NICKEL FROM VERY LOW

A process for recovering nickel from primary rock materials with a very low nickel content characterized by massive occurrences therein of a relatively uniform and very low grade of nickel in the form of sulphides, oxides, alloys and silicates, very low sulphur and low copper and iron values, low sulphur to nickel ratios and the absence or negligible occurrences of pyrrhotite.
