Design Considerations for a Tailings Disposal System | E & MJ
According to Niederhauser, more mines are looking to stack dry tailings using filtration (or a filtered cake). “There is a role for a high density thickener in this process as well,” Niederhauser said. He cited a U.S. coal application that uses a plate-and-frame press. The mine filters thickened tailings from a high density thickener.
