Clay minerals present a widespread problem in the flotation of various metals. Clay content can increase flotation slurry viscosity reducing flotation kinetics, slowing throughput and metal grade and recovery. Additionally, high viscosity and clay slime particles may adsorb onto the minerals' surfaces, reducing the efficiency of flotation reagents.احصل على السعر
Abstract In the extraction of metals from their ores, the process of mineral flotation plays a most important role. Flotation provides the means of separating and concentrating the valuable components of an ore to produce a grade of mineral concentrate suitable for feeding to efficient pyrometallurgical or hydro-metallurgical operations.احصل على السعر
