Coarse Particle Flotation in Concentrator Plants

This technical report discusses the role of coarse particle flotation (CPF) in enhancing the efficiency of concentrator plants, particularly in the context of increasing mineral demand and decreasing ore grades. It outlines two primary applications of CPF: Tail Scavenging (TS) and Coarse Gangue Rejection (CGR). The report details how CPF, specifically the HydroFloat® technology, has been successfully implemented in various mining operations, including the first industrial application at Anglo American's El Soldado concentrator in Chile. The document explains the operational principles of the HydroFloat system, which allows for the flotation of coarser particles compared to traditional methods. It also presents the benefits of CGR, such as significant reductions in milling energy consumption and the production of coarser tailings, which improve geotechnical stability and water recovery. The report emphasizes the importance of CPF as a key technology for sustainable mining practices and addresses considerations for future implementations in concentrator plants.
