A low grade disseminated nickel sulphide serpentinite ore from WA 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 leaching3 1Nickel Sulphide Resources conventional flotation process on low grade disseminated sulphide ores tends to be difficult due in large part to fines containing magnesium rich serpentine type minerals which generate slimes during comminution In most cases treatment of such ores results in low nickel
