Thickener dewatering optimization in the minerals industry

点击翻译按钮获取中文摘要

The project aims to develop the understanding required to provide a quantitative basis for the selection, design and operation of thickening devices for optimal dewatering performance in the minerals industry. This will enable reduced water use, improved water management, provide better slurry solids management and improve tailing disposal practice, resulting in reduced processing and capital costs, increased throughput and lower environmental impact. In particular, the project will link the characterisation of the slurry feed to thickener process conditions and subsequent dewatering performance, including the role of rakes and shear devices. It will provide a sound basis for the optimization of dewatering in thickener operations.
