Concentrate dewatering: higher throughput, lower costs. Dewatering iron ore concentrates is a crucial step in enhancing their handling and transportation by removing excess water. The selection of a suitable dewatering method depends on various factors, including moisture content, particle size distribution, and downstream process requirements.
