Anglo taking tailings dam monitoring to next level

Diversified mining company Anglo American is implementing new techniques that give the company far more control over tailings dams, which have been thrown into the spotlight after the tragic loss of life at Brumadinho, in Brazil, where an iron-ore tailings dam collapsed at Vale’s Corrego do Feijao mine earlier this year killing hundreds of people. The London- and Johannesburg-listed company has developed a new technique that provides information on the amount of water in its tailings dams and fibreoptic installations at some of its tailings storage facilities provide real-time monitoring of strain, deformation and seepage.
