Still, Brumadinho is one of the largest leaks in the world on the planet in the last ten years. Mariana is that he was too tall – the largest in volume of human history. Escaped 43.7 million cubic meters. In Brumadinho, according to an estimate of the fire department, 3 million (although this is not the final figure).
If it's even 3 million cubic meters, that's enough to place Brumadinho at the top of a perverse ranking. . Of the 67 other overflows of mining dams recorded in the world during the last 30 years, only 7 had a greater flow than this one (all types of mines – iron, copper, gold, manganese …) [19659007] global The increase in global ore production has resulted in more and more leaks. According to Bowker Associates, a risk management consulting firm in full construction, the decade between 1955 and 1965 recorded 6 million m 3 with such leaks. Between 2005 and 2015, with Mariana in the account, they were 107 million m 3 . And the decade between 2015 and 2025, according to the US cabinet, should end in 123 million m 3 .
In other words: security in this area tends to decrease over time, not increase, as in virtually any other human activity.
The volumes of waste do not have a direct relationship with the number of deaths. Of course, it depends on the demographic density of the accident. Mariana, with more than 40 million cubic meters, left 19 dead. A spill of 200,000 m 3 in the city of Trento in Italy killed 268 people in 1985. This accident occurred in the dam of a fluorite mine is the largest ever recorded to date . Another dam of this magnitude would only happen again in 2008, when a dam of iron ore had broken out in Linfen, China, killing 254 people.
Up to the last update of this report, Saturday afternoon 26, there were 11 dead and 296 missing in Brumadinho
