A tailings dam is typically an earth-fill embankment dam used to store byproducts of mining operations after separating the ore from the gangue. Tailings can be liquid, solid, or a slurry of fine particles, and are usually highly toxic and potentially radioactive.
Tailings dam failures involving significant ecological damage include: the Jagersfontein Tailings Dam Collapse, South Africa in September 2022, was a structural failure of a tailings dam used by a stockpile mineral reprocessor, resulting in a mudslide through the town and surrounding farmland.
The Mariana dam disaster, also known as the Bento Rodrigues or Samarco dam disaster, occurred on 5 November 2015, when the Fundão tailings dam at the Germano iron ore mine of the Samarco Mariana Mining Complex near Mariana, Minas Gerais, Brazil, suffered a catastrophic failure, resulting in flooding that devastated the downstream villages of Bento Rodrigues and Paracatu de Baixo (40 km (25 mi ...
In Brazil, more than 250 people died in 2019 when the Vale SA's Brumadinho upstream tailings dam collapsed, flooding the nearby community with mine waste. Miners need more engineers to meet new ...
It was the 11th serious tailings dam failure in the last decade and such catastrophic events are becoming more frequent, according to researchers at World Mine Tailings Failures (WMTF). Indeed ...
Mine tailings are usually produced from the mill in slurry form, which is a mixture of fine mineral particles and water. [2] Tailings are likely to be dangerous sources of toxic chemicals such as heavy metals, sulfides, and radioactive content. These chemicals are especially dangerous when stored in water in ponds behind tailings dams.
Neighbors of an iron ore mine belonging to Brazilian miner Vale SA were evacuated on Friday in southeastern Minas Gerais state, when a tailings dam ruptured, pouring out mud into the surrounding ...
The Brumadinho dam disaster occurred on 25 January 2019 when a tailings dam at the Córrego do Feijão iron ore mine suffered a catastrophic failure. [1] The dam, located 9 kilometres (5.6 mi) east of Brumadinho in Minas Gerais, Brazil, is owned by the mining company Vale, which was also involved in the Mariana dam disaster of 2015. [2]
