Leaching of Low Grade Nickel Sulphide ... - AusIMM

A low-grade disseminated nickel sulphide serpentinite ore from W.A. had a relatively high permeability after drying. Various techniques indicated that the permeability resided within a fine network of fibrous vein- lets and especially within coarse cracks along which the sulphides lay. The ore minerals were therefore open to selective extraction by chemical leaching.
