Abstract
A copper/molybdenum separation processor is provided featuring a slurry/media mixture stage configured to receive a conditioned pulp containing hydrophobic molybdenite and hydrophilic copper, iron and other minerals that is conditioned with sodium hydrosulfide together with an engineered polymeric hydrophobic media, and provide a slurry/media mixture; and a slurry/media separation stage configured to receive the slurry/media mixture, and provide a slurry product having a copper concentrate and a polymerized hydrophobic media product having a molybdenum concentrate that are separately directed for further processing. The slurry/media mixture stage include a molybdenum loading stage configured to contact the conditioned pulp with the engineered polymeric hydrophobic media in an agitated reaction chamber, and load the hydrophobic molybdenite on the engineered polymeric hydrophobic media.
