'Centrifugal Concentrator is a relatively new type of gravity concentration apparatus.' http://www.alibaba.com/product-gs/839432175/gravity_centrifuge_concentration_equipment_uranium_ore.html


This technique separates materials using high speed centrifugal force, in a shed, on the surface of planet earth. Feed material, typically from a ball mill discharge or cyclone underflow bleed, is fed as a slurry

Ablation separates the materials by blasting the ore particles way down there underground within the earths crust, out of sight. Then it is brought to the surface as a slurry.
