摘要： An atmospheric leaching process for the recovery of a nickel and cobalt from a lateritic ore, said process including the steps: (a) preparing a slurry of the lateritic ore with saline or hypersaline water having a total dissolved solids (TDS) content greater than 30 g/L; (b) leaching the slurry of the lateritic ore with sulfuric acid at atmospheric pressure, (c) recovering nickel and cobalt from the resultant leachate.

摘要： A method for separating nickel containing lateritic ore into limonite and saprolite fractions that includes subjecting a lateritic ore slurry to a size separation procedure to separate the limonite and saprolite fractions on a selected threshold particle size basis and determining a threshold particle size based on an analysis of particle size fractions by determining a particle size where substantially all of the particles having a characteristic compositional range of at least one indicator element for limonite are smaller than the determined threshold particle size, and/or substantially all of the particles having a compositional range of at least one indicator element for saprolite are larger than a determined threshold particle size.
