HPAL is largely limited to processing low-magnesium limonite ore. The higher magnesium levels found in saprolite ores increase acid consumption to uneconomic levels. Some saprolite may be incorporated into the process by using saprolite to neutralise residual acid from the HPAL step, but the volumes of this are limited.
