Exploration Orbite VSPA (TSX VENTURE:ORT.A) announces that it has successfully extracted alumina from samples of Guinean bauxite. Repeated internal laboratory tests and reviews by independent engineers have confirmed the potential of Orbite's process to extract alumina from bauxite. Orbite's radical innovation has opened the door to an immense new market for the corporation.
World bauxite resources are estimated at between 55 to 75 billion tonnes, and on average, four to five tonnes of bauxite are required to create two tonnes of alumina, from which one tonne of aluminum can be produced. At least 85% of world bauxite production is used in the manufacturing of alumina via the Bayer process(i). The Bayer process uses large quantities of electricity, produces greenhouse gases, and generates toxic red mud ponds. Each metric tonne of alumina produced creates approximately 1.5 metric tonne of red mud(ii). With more than 70 million tonnes of red mud residue generated annually from bauxite processing, the environmental cost of producing alumina with the Bayer process is significant.(iii) The bauxite market is considerable, and with Orbite's unique process, the corporation intends to continue investing time and resources in order to gain a share of this global market.
