Mariana dam burst
The scale of the 5 November tailings dam burst at the BHP Billiton/Vale-owned Samarco iron ore mine in Minas Gerais state, Brazil, continues to grow as the waste from the dam flows downstream. It seems it is becoming the biggest tailings dam disaster in history.
Krenak indigenous people are blocking Vale’s railway from the mine in protest at pollution of their only source of drinking water. The Brazilian government has fined Samarco and withdrawn its licence. Legal action is being taken on behalf of those suffering because of the disaster. Greenpeace Brazil activists targeted the BHP Billiton AGM in Perth, Australia, yesterday.
BHP Billiton touts itself as one of the most responsible companies in the mining industry. At its London AGM company Chairman Jac Nasser and CEO Andrew Mackenzie spoke of the company’s dedication to improving safety. But there are reports that warnings over the condition of tailings dams at Samarco were not heeded, and that the rush to dig up ever more iron ore, ever more cheaply, may have compromised the safety that the company says it prioritises.
If this is the best the mining industry has to offer, what of the rest?
There has been a huge amount of media coverage of the deepening crisis. The following is a selection.
