dry electrostatic air separation of gold,Selective attachment processes in ancient gold ore beneficiation .In modern gold beneficiation, electrostatic separation via triboelectricity has been tested but has no practical use (Inculet et al., 1988). However, static electricity is an essential secondary effect in the winnowing or “dry washing” of gold (Wilson, 1961); a dry washer separates gold from sand using an air pulse through a.US5375720A - Dry separation of particulate material of different .An air concentrator for dry separation of gold and other heavy minerals from alluvial deposits comprises a housing having a number of open-topped chambers arranged in a ring-like . The cylindrical casing 28A and shaft 23 of the rotary valve 28 are rotated by the electric motor 26 via coupling 25 and mounted gearbox 24.
Puffing for Gold - The New 49ersThe remaining components of a dry-washer combine to construct a sloped classification screen (or “grizzly”), which routes fine-sized material to a pneumatic sluice box, where a mechanically-modulated flow of air accomplishes the separation of gold from the lighter-weight material which contains no value.
