Aripuanã Project - Nexa Resources

The Aripuanã Project is an underground polymetallic project located in the state of Mato Grosso in Brazil. It belongs to Mineração Dardanelos Ltda. and is the result of a partnership between Nexa Brasil, Nexa Peru and Mineração Rio Aripuanã Ltda. It is the largest mineral industry project in Mato Grosso and FanTR has been chosen to carry out the ventilation project for this underground mine.

The estimated aggregate capital expenditure required for this project is US$ 354.3 million. Average annual production is expected to be 66,700 tons of zinc, 23,000 tons of lead and 3,700 tons of copper.

Ventilation includes six 400 hp exhaust fans each with a diameter of 2,310 mm. The total capacity is 600 m³/s of total volume, 200 m³/s in each well. We provided even more 23 secondary fans of 150 hp and 1,400 mm in diameter, with 37 m³/s of capacity in each.

The estimated aggregate capital expenditure required for this project was US$354.3 million. Average annual production: 66,700 tons of zinc, 23,000 tons of lead and 3,700 tons of copper.
