Description :


   As requested by Robex Resources, the consulting firm, BUMIGEME Inc., updated the costs of production of the Upton barite deposit and prepared a financial analysis of the project following the recent data on the rising prices of drilling muds and it’s increased demand, so that annual production will increase from 26 500 s.t., as previously planned, to 50,000 s.t. in the fifth year of operation. The treatment process consists of grinding the ore to a particle size of 80% - 400 mesh, a bulk flotation of sulfides, separation and cleaning of a mixed concentrate of zinc and lead by flotation, and finally by flotation of a barite concentrate.
