PARIS, August 1, 2011 /PRNewswire/ —

Imerys has completed today the acquisition of 100% of the Luzenac Group from Rio Tinto. With sales of approximately USD395 million in 2010, Luzenac Group is the world leader in talc processing. This mineral is used in many technical applications such as polymers, paints, ceramics and paper, in a wide range of end markets (industrial equipment, construction and consumer goods etc.). It will therefore strengthen Imerys leadership and product offering.

Luzenac Group will be part of the Performance & Filtration Minerals business group and will be fully consolidated as of August 1, 2011.
