Classifying concentrates using nested classifiers or sieves (30, 50, 100 mesh) will speed up the process considerably. For example, 100-mesh concentrates require more time to process than 50-mesh, etc. Keep the concentrates wet with water treated with an emergent such as "Jet Dry" to break the surface tension, and prevent fine gold from ...Web
