Challenges in processing nickel laterite ores by flotation ...
2016-6-10 · 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)

Upgrading nickel in laterite ores by flotation - ScienceDirect
2018-6-1 · 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.

Upgrading nickel in laterite ores by flotation - ScienceDirect
Pre-concentration of laterite ores by flotation was found to be possible, but it is highly determined by the ore mineralogy. In this study, no or minor upgrade in the nickel content was found for the limonite and nontronite samples. However, it was possible to obtain 40% upgrade in the nickel content (at 70% recovery) for the saprolite ore ...

2013-12-1 · Highlights High temperature experiments demonstrated that selective sulphidation is feasible. Sulphides were submicron in size but could be physically upgraded. Nickel sulphides responded to flotation and grades of 6–8% were achieved. Low nickel grade was due to fine particle entrainment. Low nickel recovery was due to issues with fine particle grinding and
