INVESTIGATION OFTHELEACHING OF THEPLATINUM-

The dissolution rates of PGMs and gold were investigated in hydrochloric acid with chlorine atambient pressure under various conditions inabench-scale stirred reactor. The PGMs dissolution rates were found to depend on the temperature, the acid concentration, the chlorine concentration, the initial particle size, agitation speed and thepressure.

Butcherbird holds other key attributes that Brown said complemented the unique leachability of the ore. The deposit is at surface, has a low strip ratio of around 0.2 to 1, and tests using the new process have shown its ore leaches rapidly with about 95% extraction in 30 minutes, rather than the traditional processing period of 24 hours.
