US Patent:
40081524, Feb 15, 1977
Filed:
Sep 15, 1975
Appl. No.:
5/613366
Inventors:
Johnny Hilmer Kleven - Burbank CA
International Classification:
B03B 574
US Classification:
209444
Abstract:
Heavy metals such as gold, silver platinum, copper, etc. , in the free state, are separated from their ore by applying water and the ore in finely divided form to at least three rotating, inclined, spiral grooved discs driven from a common shaft. The grooves are closely spaced and with declining pitch from the periphery to an annulus at the center of the disc. The free metal tends to sink to the bottom of the grooves and the lighter ore is washed away as the metal moves along the spiral grooves to the annulus. The free metal and any remaining ore is fed from the annulus to the succeeding disc and the process is repeated.
Johnny Kleven from Burbank, CA, age ~84 Get Report
