The ore goes for preliminary screening, followed by stream sampling, which is a process that uses a hammer sampler. A semi-autogenous mill (SAG) or ball mill is then used to grind and crush the gold ore to a smaller particle size. After this milling, the stream is fed to a trommel screen and next, a cyclone circuit.
