Donkey mill at La Alcogida Ecomuseum in Fuerteventura. A horse mill is a mill, sometimes used in conjunction with a watermill or windmill, that uses a horse engine as the power source. Any milling process can be powered in this way, but the most frequent use of animal power in horse mills was for grinding grain and pumping water. Other animal engines for powering mills are powered by dogs ...

CMM ore was ground in a rod mill, as is common before flotation testing, and PGM ore was ground in a ball mill, as is common before leach testing. The plant cyclone overflows could not be used for such purposes because of gravity gold recovery in the grinding circuit at PGM, and because of CMM flotation feed (cyclone overflow) sample aging.
