Gold Gravity Concentration - Mineral Processing & Metallurgy
The object of gravity concentration is the separation of the heavy valuable mineral from the light worthless gangue Complications are often introduced by the fact that various base minerals must be separated from one another, an ore being subdivided into several products Most gold ores, however, only require separation into two parts—the “concentrates,” in which the precious metal is .
The flow sheet of a gravity process is rather simple It generally consists of a conditioning and sizing of the feed material followed by one ore two stages of gravimetric gold recovery Gravity concentration of gold, Agricola (p16), “Long Tom” (p17) Shaking table (p18) Humphreys spiral concentrator (p19) 12 ,
