Its production mode of alumina has changed from a batch process to a semi?continuous process. The increased production means the company can meet demand as well as prepare for a the transition of the plant to a High?Purity Alumina production facility.
The extra capability allows the plant to potentially operate full?scale industrial conditions over three daily shifts allowing for operations to produce, 24/7 days a week.
Analyses carried out by independent groups including SINTEF and INRS, have confirmed that the physicochemical properties of Orbite’s alumina material meet or exceed the standard specifications of the aluminium industry.
These specifications, which include bulk density, particle size and specific surface, are specific to the aluminium smelter industry.
Production at Orbite’s plant used the first 400t of an aluminous clay bulk sample collected from a deposit 23m south of Grande?Vallee in 2010.
A new bulk sample of more than 3000t has been extracted and will be shipped to the Cap?Chat plant. This sample will enable the continued operations of the facility for another year.
About 250-300t of clay have already been processed at the Cap?Chat facility. The company has produced about 70t of alumina and associated products and has begun making the necessary investments in order to convert its Cap?Chat facility for continuous production of high?purity alumina.
The alumina, alumina hydrates and aluminum leachate samples have been used in producing external tests and analyses with research centres of excellence in Canada and Europe, in the production of aluminium products and samples. These will be used for third party validation and testing with engineering development partners, for continuous testing as well as economic optimisation.
