PLACER GOLD RECOVERY METHODS - GOLD MINING & …
major flaw of the gravity separation method is that very fine gold, referred to as flour, flood, or colloidal gold, is lost in processing. Early miners recovered no more than 60% of as-sayed gold values, and as late as 1945 recovery of free gold averaged only 70-75% (Spiller, 1983). Moreover, it is likely
Gravity Separation - an overview | ScienceDirect Topics
Gravity separation relies on different specific gravity of minerals and their relative motion under gravity and drag forces. This chapter describes units, circuits, and strategies that are used to recover gravity-recoverable gold (GRG) from very high-grade gold particles and from sulfidic particles with low-grade gold …
