QUEBEC - The Industrial Research Assistance Program of the NATIONAL RESEARCH COUNCIL OF CANADA (NRC-IRAP) is contributing both technical advice and money to EXPLORATION ORBITE of Montreal, as the latter seeks to develop a new technology to extract aluminum from clay tailings. The contribution will cover 47% of the program costs, according to Orbite.
This project, to be carried out by the CENTRE D'ÉTUDES DES PROCÉDÉS CHIMIQUES DU QUÉBEC (CEPROCQ), will develop a new liquid-liquid separation approach to selectively separate aluminum ions. "The objective is to increase the economic and ecological efficiency for the Grande-Vallée alumina clay treatment process," said Richard Boudreault, Orbite's president.
The Grand Vallée clay lixiviation tailings are found near Murdochville. An estimated 16.5 million m³ of material containing between 23% and 24.4% alumina has been outlined. Further exploration of the property is planned.
