Abstract:Filtration is widely used in the dewatering of concentrates and tailings in coal preparation plants and mineral processing plants, and its operation efficiency is crucial to product quality and high-performance operation of processing plants. Improving the filtration efficiency of pulp is an important topic in the field of mineral processing both domestically and internationally. In this paper, three key factors, slurry physicochemical properties, filter media, and filtration driving forces, were systematically discussed, and a comprehensive review of recent advancements in physical and chemical enhancement techniques during the dewatering process were provided. Furthermore, the study proposes principal development directions and future trends for pulp filtration and dewatering technology.
