Stamp Mill - Mineral Processing Metallurgy

17/03/2017  When stamp mills are used for dry crushing, double discharge mortars are provided (see Fig. 50), and the screens are put low down, giving a small depth of discharge. These arrangements are necessitated by the difficulty of discharging the crushed ore from the mortar, the only means of doing this being the dashing of the dry ore against the screens, due to the fall of the stamps.

Stamp Mills Superstition Mountain – Lost Dutchman

The stamp mill provided an invaluable need for the early gold miners. Unlike placer deposits that produced gold nuggets already separated from rock, lode gold deposits were of little value if the gold could not be efficiently removed from the host rock.

Crushed ore is fed into Mills in which the ore is mixed with water and may be ground down to a particle size, in the case of gold and copper, of about 75 microns (0.075mm). The fine, powdered ore emerges from the mills mixed with water in a thin, wet paste called Pulp or Slurry. In the ASM sector, Stamp Mills are still in common use, especially in gold mining, but the more efficient and m ...
