Placer Mining Methods PLACER GOLD RECOVERY

2016-10-26  The 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).
