  • Flotation | ore dressing | Britannica

    Flotation is the most widely used method for the concentration of fine-grained minerals. It takes advantage of the different physicochemical surface properties of minerals—in particular, their wettability, which can be a natural property or one artificially changed by chemical reagents. By altering the coal mining: Separationfine coal, a process called flotation achieves this purpose

    30/01/2015· INTRODUCTION Flotation is the separation of particles from a mixture by causing some particles to collect on the surface of bubbles. Floatation is an extractive process where various minerals can be selectively extracted. For example, in poly-metal ores such as Pb-Zn-Cu, floatation allows separate extraction of Pb, Cu and Zn. The process of separation of mineral includes three important
