COBALT: Canada Cobalt’s Re-2OX process makes premium grade sulphate

ONTARIO – Canada Cobalt Works of Coquitlam, B.C., says its proprietary Re-2OX process has made the first ever, premium grade cobalt sulphate. At 22.6% the grade exceed the technical specifications of cathode producers in Asia, who may be Canada Cobalt’s first customers.

SGS Lakefield conducted the pilot scale tests on cobalt-rich gravity concentrate from the Castle mine near Cobalt. Using the Re-2OX process eliminates the need for smelting the concentrate. Metal recoveries from the concentrate were 99% for cobalt, 81% for nickel and 84% for manganese, while 99% of the arsenic was removed.

Canada Cobalt says it will scale up the Re-2OX process this quarter. The company intends to create nickel-manganese-cobalt formulas for the battery market.
