    EquipmentScopeIndustryResourcesResultsCompositionIntroductionTerminologyThe concentration of placer gold ore consists of a combination of the following three stages: roughing, cleaning, and scavenging 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 Unfortunately, such separations are never perfect, and in practice some waste material is included in the concentrates and some gold remains in the tailings Middlings, particles that belong in ei
