The figures are of particular interest since
there was no NFG reporting to the concentrate and the grade and
recovery of the sulphides is totally dependent on their rate of flo-
tation and the amount of gangue being recovered by entrainment,
i.e. the stability of the froth. For guar gum addition at 500 g/t the
increase in water recovery resulting from the increased frother
dosage led to a decrease in nickel grade with an equivalent but
smaller change in the copper grade.
