[BRAZIL - Alcoa launches a new mine in Juruti with Metso . . .cont]

"There is a monitoring system that provides extensive resources for operation and supervision of the entire process in a simple, versatile, effective and safe manner that further minimizes operational errors and enables monitoring and proceed production analysis", says Equi.

Ship loader is able to move along the quay for faster turaound of ships there by reducing costs.The Juruti operations, which are part of the Alcoa World Alumina and Chemicals (AWAC) joint venture with Alumina Limited consist of a port facility, a mine and a 50 km rail system to the port.

Bauxite from Juruti will be shipped to the Alumar alumina refinery in Sao Luis, Brazil which is undergoing a 2.1 million tonne per year expansion program that will bring total production there to 3.5 million tonne per year.

“We have taken steps to make the Juruti project the best mining project in the world - world-class in terms of efficiency and our commitment to sustainable development principles,” said Franklin Feder, President of Alcoa Latin America. “This mine will serve our operations in Brazil and lower our costs. At the same time we will mine bauxite and return the area to the same, if not better, condition than when we initially arrived. Our commitment is to deliver on both the business efficiency and the stewardship of the region.”

The Juruti Project will mine, and re-vegetate, a total of 6,000 hectares over a period of 40-60 years. That is equivalent to one day’s worth of the current deforestation in the Amazon according to the latest data published by Brazil’s Ministry of the Environment.

Recognizing that no permanent deforestation is acceptable, Alcoa has already been working with NGOs and reforestation experts to ensure that the mined-out areas will be totally re-vegetated with native species.

Truck cars carry the reclaimed material to the coneyor system for the ship loaders.For every Brazil nut tree removed during the mining process, Alcoa will replant 10 trees.

And for every other species of tree impacted during the process, Alcoa will replant 2 trees for each tree removed. In total, Alcoa estimates it will plant 15 million trees over the next 50 years in the Juruti region.

The Juruti Mine is located in the West of the State of Pará, right in the very heart of the Amazon rain forest.

Juruti is an old township, dating back some 125 years, and according to data from the Brazilian Institute of Geography and Statistics (IBGE) 2007, it has 34,000 inhabitants, of which 60% live in the 150 rural communities that predominate in the region.

Its economy has been traditionally based on the growing of manioc, fishing, livestock farming and gathering from Truck cars carry the reclaimed material to the coneyor system for the ship loaders.nature.

With reserves of around 700 million metric tons of top quality bauxite Juruti has one of the largest deposits in the world, material that is going to be necessary to meet growing demand and which has also made it possible to expand Alumar (Aluminium Consortium of Maranhão) in São Luís (MA). Initial production at the Juruti Mine will be 2.6 million tonne.
