Doubleview Gold Corp. provided additional information regarding the metallurgical process and significance of achieving 56% scandium recovery to a scandium phosphate precipitate, in the first attempt of sequential purification of HAT deposit flotation tailings. The HAT Copper-Gold-Scandium-Cobalt deposit is located in the Golden Triangle region of the Atlin Mining District in British Columbia.

Initial independent laboratory tests completed by Coffey, Tetra Tech were designed to demonstrate the validity of the underlying process chemistry. Achieving 56% Sc recovery shows that primarily, the response to the treatment program was predictable and as anticipated. Expectations are that scandium recoveries in the range of 80% to 90% will ultimately be achievable with further process development and optimisation.

Production of a phosphate lends itself to the solution purification scheme currently under test. Once recovered, scandium can be converted to other forms. Alternative treatment strategies are also being considered. Scandium is associated with crustal rocks and mafic and utra-mafic lithologies such as amphiboles and pyroxenes (in particular clinopyroxene) and so is primarily associated with the tails stream of a conventional copper flotation process employed in the treatment of a porphyry ore.

In a fully integrated process, the HAT deposit could produce a high-gold, low-cobalt copper concentrate and a low-gold, high-cobalt pyrite concentrate. The pyrite concentrate could be used to produce acid for the recovery of cobalt from roaster calcines and scandium from flotation tails. EUR ING Andrew Carter B.Sc.
