    This process is repeated to concentrate the gold bearing ore and separate it from the waste rock (increasing the grade of the ore). The flotation units catch 70% of the gold collected at Macraes, with the primary roughers collecting the other 30%. The slurry that doesn’t contain any gold is neutralised and sent to the tailings dam.
