On the other hand, AG mills, or Autogenous Grinding mills, use only the ore itself as grinding media. They are smaller in size than SAG mills and can be used for smaller quantities of ore. AG mills are often used in the mining industry for the processing of precious metals such as gold and silver, as well as lead, zinc, and nickel.

Under exceptional circumstances a gold ore may prove to be satisfactorily handled by roasting and amalgamation. Panamalgamation, whether the ores treated are raw or roasted, may be conducted in one of two ways. The older system is to crush wet in the stamp mill, and collect the ore in large shallow settling pits or pointed boxes (see p. 172).
