Tailings treatment system to prevent tailings dam from breaking

Rio de Janeiro, February 11th: Brazilian Vale’s 2019 production and sales report released on the 11th showed that the company’s iron ore output in 2019 was 302 million tons, a 21.5% decrease from 2018. The dam rupture accident is an important factor leading to the decline in production.

At the end of January 2019, Vale’s tailings dam collapsed in Brumadinho, southern Brazil. Waste mud swallowed up residential areas, killing more than 250 people. After the accident, many other mining areas of the company were also shut down by the government, and production was severely hit.
