Orbite makes headway towards final calcination stage of high purity alumina production

Quebec clean-technology firm Orbite Technologies continues to make progress towards achieving the calcination stage of its high-purity alumina (HPA) plant, through which it will "soon" be producing ultra-pure alumina, the company said Thursday. The TSX-listed innovator said feedstock digestion continued to operate automatically and smoothly at the HPA plant, in Cap-Chat, and digestion liquors continued to be transferred to the crystallisation circuit to produce aluminium chloride hexahydrate (ACH) crystals, the precursor to HPA.
