McArthur River – world 39 s top producing uranium mine in 2010 Country Mining Crushing amp Grinding Leaching Separate solids Tailings disposal In situ
Alkaline leaching of uranium from limestone media has been practiced Conventional milling involves crushing and grinding the ore the yellowcake
For example in the acid leaching area the tanks vent through wet scrubbers that Powered by a 250 horsepower mill semi autogenous grinding is used in this process The uranium bearing ore is crushed and ground and then after cycloning The process continues to the solvent extraction units and yellow cake drier
Production of uranium concentrates in the form of U3O8 or Yellowcake as it is The first stage is crushing and grinding where the ore is reduced down to grains to ensure that the uranium mineralization is exposed to the leaching agents
