Hard rock or “Lode” gold is still contained within ore and various methods are used to extract the metal from the rock that surrounds it Placer gold on the other hand occurs when natural erosion has released the gold from its host material and the gold is now a separate piece whether that be a small speck of gold dust or a large gold nugget

Centrifugal Gold Concentrator The key components of the unit are a cone shaped concentrate bowl rotated at high speed by an electric motor and a pressurized water jacket encompassing the bowl Feed material typically from a ball mill discharge or cyclone underflow bleed is fed as a slurry toward the centre of the bowl from above

In operation material is fed as mixture of milled rock and water into a rotating bowl that includes special fluidized grooves or riffles to capture the heavy minerals Periodically a rich mineral concentrate is rinsed out that requires further upgrading to be turned into a final gold product

It quickly settles down to the bottom of the pan as gold is much denser than rock Usually the panning material is removed from stream beds often at the inside turn in the stream or from the stream’s bedrock shelf where gold density allows it to concentrate a type called placer deposits
