  • Upgrading nickel in laterite ores by flotation ScienceDirect

    01.06.2018· Flotation has not been successful to recover nickel from laterite ores because of the fine-grain and low grade nickel. 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.

  • FLOTATION OF LATERITIC NICKEL ORES WESTON D,CA

    This invention relates to the beneficiation of nickel bearing laterite ores by means of froth flotation. As is well known, nickel-bearing laterites occurring in large deposits in various parts of the world constitute the biggest reserve of nickel ores presently known. These laterites vary in their nickel, cobalt and iron contents and all are of a generally similar type with a mineral structure about which very little is known

  • Flotation Cells For Nickel Laterite Ore

    Upgrading Nickel In Laterite Ores By Flotation. Jun 01, 2018 Quast et al. (2015a) have concluded that the complex mineralogy of nickel laterite ores makes it difficult to achieve any significant nickel upgrading by physical techniques, including flotation. They achieved 40% increase in the nickel content (from 1.0% to 1.4%) at a nickel recovery of 43% ( Quast et al., 2015c ).

    Production of Nickel from Lateritic and Sulfide Ores . In 2009, the world’s top nickel producers were Russia, Indonesia, Canada, Australia, and New Caledonia. Nickel is produced primarily from laterite and magmatic sulfide deposits. Laterites comprise approximately 70% of the world’s nickel deposits, while only contributing to about 40% of global production. Laterite is rock formed in tropical and subtropical climates, over long periods of erosion, and nickel-bearing laterites

  • Preconcentration strategies in the processing of nickel

    The preconcentration of nickel (Ni) laterite ores ahead of Ni recovery by hydrometallurgical processing makes good economic sense. Since Ni-bearing minerals are often finely disseminated through laterite ores, liberation of minerals either high and/or low in Ni content is a prerequisite prior to any form of separation process. It is the purpose of this paper to investigate the use of flotation

  • Enhanced methods for nickel recovery from low-grade

    Laterite formed from the weathering of serpentinite, for example, contains 45-55% iron and about 1% nickel, this is known as nickeliferous iron laterite. The other type of nickeliferous laterite is known as nickel silicate, which contains less than 30% iron, 30% silicon dioxide, and about 1.6% nickel. In general, laterite has high concentrations of iron, titanium, and aluminum oxides.
