Flotation Of Nickel

Dec 01, 2013 The absolute nickel recovery is based on the total nickel content of the ore, while the recoverable nickel is based on the amount of nickel sulphide present after sulphidation. The overall economics and suitability of the process relies on the total nickel recovery, whereas the flotation performance should be assessed on the recoverable nickel

Most of the world’s nickel is extracted from the mineral pentlandite, (Ni, Fe)9S8, which frequently occurs in ores containing predominantly pyrrhotite and various non-sulRdes, some of which contain magnesium (Table 1). The nickel content in such sulRde ores is generally low (0.2}3%) and varies from place to place in the same deposit. The low nickel content of the present-day nickel sulRde

A method of concentrating nickel sulfide ores by flotation which comprises subjecting the ore in the form of a pulp to a flotation process in the presence of an effective quantity of a flotation collector comprising a dithiocarbamate compound corresponding to the formula ##SPC1## Wherein X is oxygen or sulfur and R is hydrogen or a hydrocarbon radical containing from 1 to 10 carbon atoms; R 1

Flotation of a Canadian nickel ore by N-hydrocinnamoyl-N-phenyl hydroxylamine (HCNPHA), also called N-phenyl hydrochuiamohydroxamic acid (see Figure 1 for structure) and the comparison of performance of the synthetic collector with that of potassium amyl xanthate (PAX) are reported here. Such a comparison of a synthetic collector with that used

A process for the beneficiation of nickel bearing laterite ores by means of froth flotation wherein a dispersed pulp of the ore is conditioned with a fatty acid type collecting agent either at an elevated pH to produce, following flotation, an enriched flotation tailing or at a reduced pH to produce, following flotation, an enriched flotation concentrate

The useful minerals of Jinchuan high-grade copper and nickel suphfide ores were mainly nickel and copper, whose grade were respectively 1.42% and 1.01%. The content of MgO and SiO2, main gangue components, reached 57.89%. The key to improve the separation indexes of flotation concentrate was to inhibit the gangue minerals effectively, therefore, the effects of different kinds of regulators on

The second stage of froth flotation produces a nickel concentrate of 10-20% Ni, along with other by-products and gangue. Smelting is the next stage, designed to recover as much metal as possible. Flash smelting is a common method: dry concentrates are fed into a furnace and heated to a liquid matte and slag. From this step, sulfide matte can be

Some plants use bulk flotation in an acid pH environment which is achieved using SO2 or H2SO4. 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

2. 2. Flotation Procedure 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 m was weighed and placed in the flotation cell. This was followed by the addition of distilled water to about

The results revealed that rheology, which is caused by pulp density, played a key role in flotation performance. The decline in density (from 40 wt % to 20 wt %) increased the nickel and copper recoveries from 70.7% to 79.5% and 82% to 85.4% respectively in the artificial mixture (1:1)

Sep 15, 2011 Air flotation is an efficient way to separate light particulates and oils from wastewaters. Nickel (II) and aluminum (III) removal by the combined biosorption and flotation process named biosorptive flotation was studied in laboratory scale. The Rhodococcus opacus strain was used to assist the removal of the toxic metals by biosorption.
