Bloomberg reported that after reaching 400 million metric tons of iron ore output in 2017, Vale SA (NYSE:VALE) plans to increase its iron ore output by 20 to 25 million metric tons per year. Vale's plan is aimed at taking back the 6 percent of market share that it has lost to other major companies — such as BHP Billiton Ltd. (ASX:BHP,NYSE:BHP,LSE:BLT) and Rio Tinto plc (ASX:RIO,NYSE:RIO,LSE:RIO) — over the past six years.
