The concentration of placer gold ore consists of a combina-tion of the following three stages: roughing, cleaning, and scav-enging. The object of concentration is to separate the raw ore into two products. Ideally, in placer gold recovery, all the gold will be in the concentrate, while all other material will be in the tailings.
