  The selective flotation of pentlandite from a nickel ore

  Jun 01 1995  Bulk flotation An efficient procedure for nickel recovery is to combine copper sulphate to activate pentlandite with guar gum to depress talc. This is the method which has been used for the flotation of nickel ores in industry and which we have termed the standard bulk float . A selection of results for this ore is given in Table 3.
