• Tailings ROHR-IDRECO

    Tailings. Historically, mining processes with poor recovery rates have resulted in tailings with significant amounts of recoverable material. This material can be extracted with dredgers, however. Typical applications can be found in the coal, iron ore, gold, diamond, copper, oil sands and other mining sectors.
