  • MEI Blog: Challenges in processing nickel laterite ores by

    Flotation has not been successful in recovering nickel from laterite oresas the nickel is often finely disseminated in various minerals at a very fine size. Ultrafine grinding has to be used to liberate nickelcontaining particlesbut the resultant fine particles means that recovery is low in conventional flotation cells. The authors suggest that using reactorseparator cellswith more

    For examplein New Caledonianickel is concentrated either in finegrained laterite where goethite is the main nickel bearer (lateritic ore) or below the laterites as mixtures of hydrous MgNi silicate and goethite (saprolite ores) (Dublet et al.2012).

  • Challenges in processing nickel laterite ores by flotation

    The association of fine grained MgNi silicates with oxyhydroxides in laterites and saprolites represents challenges for ore processingin particularin nickel enrichment.

  • Upgrading nickel in laterite ores by flotation ScienceDirect

    Preconcentration of laterite ores by flotation was found to be possiblebut it is highly determined by the ore mineralogy. In this studyno or minor upgrade in the nickel content was found for the limonite and nontronite samples. Howeverit was possible to obtain 40% upgrade in the nickel content (at 70% recovery) for the saprolite ore sample using flotation.
