Precipitate flotation of nickel from acidic laterite leach

1985-8-1  Precipitate flotation has been used to preferentially concentrate nickel over iron dissolved in solutions obtained by sulfuric acid leaching of a selectively reduced laterite. Leach solutions, containing about 3 g/L nickel, 0.5 g/L ferrous, 0.5 g/L magnesium, were neutralized using sodium carbonate to give mixed precipitates of a basic nickel carbonate and mainly non-carbonate iron compounds.

Upgrading nickel in laterite ores by flotation

2018-6-1  David (2008) has highlighted that the lack of success in upgrading nickel in laterites via flotation is due to the absence of a specific nickel rich phase in laterite ores. In fact, nickel is present in a number of soft minerals which can easily report to the slimes during milling.

FLOTATION OF LATERITIC NICKEL ORES WESTON D,CA

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.

2013-12-1  It was found that the nickel sulphides responded to flotation at pH 9 with PAX and TETA additions and that maximum grades of between 6 to 8% were achieved with the average cumulative grade of the nickel concentrates having values of between 4 and 5 wt.% nickel. Cumulative recoveries were low, with values between 50% and 60% on a sulphide basis, which corresponded to a 35–45%
