Orbite Aluminae has started the conversion of its pilot high-purity alumina (HPA) plant in Cap-Chat in Quebec, Canada to a full-scale production plant.

The aggregate construction costs for the HPA plant are expected to range between $26m and $30m, and are subject to approval from governmental authorities.

Canam Group will carry out the design and construction work for the new plant, while Gastier in coordination with local contractors will manage the project.

The plant's calcination work will be carried out by European-based Outotec, which is already engaged in Orbite's smelter grade alumina production activities.

In parallel to the high-purity alumina calcination unit, Orbite will regenerate the hydrochloric acid produced.

Laurentide Controls will support Emerson Process Management to enhance the profitability of the Orbite's patented process control extraction technology.

"In parallel to the high-purity alumina calcination unit, Orbite will regenerate the hydrochloric acid produced."

Al Novak, Emerson metals and mining director, said: "We will help Orbite reduce its operating costs and assure the efficiency and safety of the future day-to-day operations at the production plant."

The plant is expected to produce three tons of alumina each day within 12 months of start up.

Denis Primeau, Orbite chief engineer, said the company is also being supported by Andritz and Pfaudler.

"Construction of the Orbite high-purity alumina plant will be carried out in four phases: the foundation and infrastructure will be completed by the end of July 2012; the structure and exterior will be finished in September; the mechanical systems and electrical installations will follow, and commissioning of the plant is slated for December 2012," Primeau said.
