YAOUNDE, Cameroon-Canadian metal giant Rio Tinto Alcan has said it will quit a consortium it formed with Cameroon's smelter Aluminium du Cameroun, known as Alucam, in December.

"Rio Tinto is proud of its long participation in the Alucam Group over several decades; however, the Alucam Group's new business model no longer fits with our strategy," said president and chief executive of Rio Tinto Alcan, Arnaud Soriat, in a statement published this week.

The Cameroon government, which owns 46.67% of Alucam--the same amount as Rio Tinto Alcan, built the smelter in 1957. The French Development Agency controls 5.6% of Alucam shares, while the remainder 1.1% is held by Alucam's employees, according to data from Alucam.

There are plans to increase Alucam's alumina output from 90,000 metric tons a year to around 300,000 tons yearly by 2017. But energy shortages have forced Alucam's aluminum output to plunge in recent years to around 80,000-60,000 tons/year, according to its figures.

The expansion of Alucam has hinged on a gigantic hydroelectricity scheme, through which Rio Tinto planned to increase power supply by 330 megawatts.

Rio Tinto also had another scheme to erect a second hydropower plant with 930 megawatts of electricity in the Atlantic coastal town of Kribi, where it had aimed to build Cameroon's second smelter with a capacity to produce 800,000 tons of aluminum yearly.

Rio Tinto Alcan said it has also offered to help the government of Cameroon to find a new investor in the Alucam Group.
