SAO PAULO, BRAZIL (December 9, 2005) - GL&V Brasil Ltda, a subsidiary of the Canadian-based company Groupe Laperrière & Verreault Inc., recently announced that its Dorr-Oliver Eimco division received a major order for the supply ten (10) 160 cubic meter cells and six (6) 21.5 cubic meter flotation units to Mineração Maracá Indústria e Comércio S/A, one of Yamana Group’s copper and gold mine operations, located in Alto Horizonte, State of Goias, Brazil.

In the past, mineral producers had to choose between mechanical flotation systems that naturally ingest ambient air and others that induce air with a blower. To meet today’s specialized plant requirements, Dorr-Oliver Eimco introduced a flotation circuit that utilizes proven Wemco® self-aspirated technology and Dorr-Oliver® forced-air cells to ingest air in order to maximizing overall plant recovery and final concentrate grades..

Dorr-Oliver Eimco previously introduced this concept of integrating the benefits of Dorr-Oliver and Wemco flotation cells in other parts of the world, this being the first ordered in Brazil. By supplying customized solutions to its mineral processing partners, Dorr-Oliver Eimco maintains its global industry leadership in the supply of flotation technology with over 53,000 flotation cells delivered to date.
