Tailings Management Solutions: Maximizing Water Reuse
06/03/2020· In the mining and mineral processing industries, the term "tailings" refers to waste materials that remain after the desired minerals have been extracted from the mined ore in a processing plant. We recently partnered with our channel partner in Africa, Multotec, to bring a filter press technology solution to a chromite mine.
