PERTH (miningweekly.com) – Japanese major Mitsubishi Corporation has inked an agreement with ASX-listed Cobalt Blue to test its sulphur by-product at the Thackaringa project, in South Australia.
Thackaringa is expected to produce some 4 000 t/y of cobalt and 300 000 t/y of elemental sulphur, which will be in a prilled form, suitable for long-distance transport and rehandling.
Cobalt Blue has produced some 75 kg of elemental sulphur to date as part of its scoping and feasibility studies, and is working with a Canadian firm to turn the powdered sulphur into prills.
Under the agreement, Mitsubishi will conduct marketing trials for the elemental sulphur. If the trials prove successful, the parties would negotiate an offtake contract for the commercial production and sale of the by-product from Thackaringa.
