Friday's collapse of a Vale-owned dam in Brazil may cause further pain for a dry bulk sector already smarting from a slowing Chinese economy.

The Bela Horizonte barrier used for holding waste water and mud from the Fiejao iron ore mine burst wide open, resulting in the loss of 34 people and more than 300 missing so far.

Beyond loss of life, the second such Vale disaster in three years may result in serious misfortune for the entire dry bulk sector, particularly capesize vessels and owners, says Stifel analyst Ben Nolan.
