MONTREAL — Orbite Aluminae Inc. has started construction of its high purity alumina (HPA) production facility in Cap-Chat, Que.

The Montreal-based cleantech company said the first phase of construction entails the structural reinforcement of the HPA building structure required for the installation of the Outotec calcination equipment.

Orbite describes its patented process as crushing, then acid leaching aluminous claystone. By using various temperatures and pH levels, the process selectively isolates the aluminum component and removes iron and other impurities.

Commercial production is to begin in the first quarter of 2015.


The company’s proprietary processes produce alumina and other high-value by-products, such as rare earth and rare metal oxides using feedstocks that include aluminous clay, kaolin, nepheline, bauxite, red mud and fly ash.

Orbite has also completed the basic engineering for a smelter-grade alumina production plant, which would use clay mined from its Grande-Vallée deposit.
