Gravity Separation The Anchor House Inc
Sep 09, 2016 This difference allows for an efficient separation to be possible. Other important factors are the size and size distribution of the REE minerals, with the coarser grain size being more efficiently recovered. However, there are enhanced gravity machines that can recover high specific gravity minerals down to 10um.
How Gravity Separation Works To Recover Metals And Minerals
Some of the earliest recordings of this science in practice are from Ancient Egypt as workers panned for gold in the Nile river. While todays geology enthusiasts still pan for gold in streams, Sepro has taken the science of gravity separation and optimized it, making gold recovery at microscopic levels not only possible but economically viable.
