In this process saponified tall oil fatty acids added with oxyethylated alkyl phenols—Neonol AF 9-10 and Kemir М-246—are used as collectors.
Magnetite is a kind of mineral which is easily beneficiated. Generally, lean iron ores are processed by gravity separation, magnetic separation, flotation and roasting-magnetic separation combined processes, and strong magnetic iron ores are processed by magnetic separation directly. In recent years, the granularity of magnetite has been gradually refined and the requirement of iron
FLOTATION PROCESS FOR MORE EFFICIENT COAL RECOVERY Froth flotation is a widely used, cost effective particle separation process. However, its high performance is limited to a narrow particle size range, e.g., between 50 µm and 600 µm for coal and between 10 µm and 100 µm for minerals. Outside this range, the
