Brazilian miner Vale SA’s shares plunged on Monday, wiping out nearly 62 billion reais (US$ 16.4 billion) in market value, after a tailing dam collapse on Friday killed at least 65 people and left 292 missing with slim hopes for recovery. Vale shares were down 21.5% in Sao Paulo morning trading, at 44.70 reais. The company suspended dividend payments late on Sunday.
