摘要:
This invention relates to a method for processing nickel laterite ore, including the steps of obtaining a mined laterite ore from a mining operation 42; and feeding the ore through a bulk sorter 44 comprising a sensor arrangement and a diverting mechanism that separates the ore into a beneficiated stream of nickel laterite ore 28 wherein the grade of nickel is higher than the grade of the ore fed into the bulk sorter for further processing 52 by leaching or smelting; one or more low grade fractions of ore 50 with a lower nickel grade than the beneficiated stream; and a waste fraction 46. This configuration efficiently separates lower grade patches in the run of mine ore, to either a low-grade stockpile or waste, and efficiently blends the selected high-grade ore to meet the specifications of the subsequent processing.
