Upgrading nickel in laterite ores by flotation - ScienceDirect

Jun 01, 2018  In this study, upgrading nickel by flotation in three laterite ore samples, limonite, saprolite and intermediate, from different geology zones, was investigated. It was possible to upgrade the nickel grade in the saprolite sample by about 40% at more about 70% recovery using a hydroxamate collector at pH 10. These grade and recovery results are ...

Upgrading nickel in laterite ores by flotation - ScienceDirect

Nickel laterite deposits are generally divided into limonite (oxide), nontronite (clay) and saprolite (silicate) zones. A systematic study was conducted on the ore samples sourced from these three categories to see the effect of different mineralogies on the flotation behaviour of laterite ores.

Jun 10, 2016  It should be added that segregation of laterite ores prior the flotation process has shown some improvement in upgrading nickel. The segregation process relies on the addition of calcium chloride or sodium chloride and carbon allowing the formation of nickel and iron chlorides at temperatures between 900 and 1150 °C.Iwasaki et al., (1961) and Nagano et al., (1970) have reported nickel ...

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.
