A Brazilian court has issued an injunction stopping operations at several tailings dams owned by Vale.
The mining giant said that the injunction would hit production at its major Brucutu mine, which Vale had said last week would reopen within 72 hours after authorities gave it permission to do so.
The new injunction was issued after prosecutors in Minas Gerais state brought a legal motion, and requires Vale to cease operations at 13 tailings dams.
In January, the breach of a tailings dam at Vale’s Brumadinho mine in Minas Gerais left more than 300 people dead. This followed another deadly tailings dam collapse three years earlier in the same state.
Consequently, the miner is facing increasing pressure over the safety of its tailings dams.
The Brucutu iron ore mine has an installed capacity of 30 Mt, representing 8% of Vale’s annual output. The firm said that mining operations at other mines remain unaffected.
