:: World’s Largest Flotation Cells Improve Copper and Molybdenum Recovery in Mexico

 

The first two Outotec TankCell® e630’s – the largest operating flotation cells in the world at 630 m3 – are running at the Buenavista del Cobre (BVC) concentrator in Northern Mexico. Start-up was completed in March 2018, and since then the site has reported an increase of more than 3% in overall recovery. Also, e630´s produce higher Cu grade in the concentrate (24% Cu), which can be sent directly to Cu-Mo separation plant.

“This is the highest recovery I have seen at BVC Concentrator 1 since my first site visit back in 1988,” said Jose Romero, Head of Sales for Outotec’s office in North Mexico. “This is a huge benefit for Grupo Mexico, and they have been very happy with Outotec’s technical approach.”

Buenavista del Cobre is a copper-molybdenum mine located in the state of Sonora, Mexico. The mine has two concentrators: Concentrator 1 is a 90 ktpd plant which has been in operation since 1986 while Concentrator 2 is a 100 ktpd brand new plant design that started-up in 2014. The flotation improvement reported in this work with the latest TankCell e630 technology was carried out at Concentrator 1.

Concentrator 1 has been in operation for more than three decades and was originally designed for 72 ktpd. The ore is mined from an open pit, crushed, and fed to ten ball mills. The concentrator is divided into two parallel comminution-flotation sections, so that five ball mills feed each flotation section. Both sections consist of three bulk copper and molybdenum rougher flotation lines, and the rougher concentrate is transferred to a regrinding stage.
