Placer Gold Mining Methods. gold deposits grouped together under the name of " placers " comprise sands, gravels, or any loosely coherent or non-coherent alluvial beds containing gold. They have accumulated owing to the action of running water, in the beds of rivers, or on the adjoining inundation plains, or on sea beaches.Web
With alluvial gold it is actually very unusual to find a scenario where gold is so fine, that a centrifugal separator is required. The reason for putting the magnet AFTER the concentration device is so the mass flow to the magnet will less. Magnetic separators are usually low volume devices.Web
