1 Froth Flotation – Fundamental Principles. Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and removed, while

Only the flotation process mentioned above could make this practicable; and even so, it requires large companies with huge plants, continuous working and immense capital. This explains why, in order to smelt 4 million tons of new copper in 1963, nearly 400 million tons of ore had to be handled and treated in various ways. Flotation depends on

· Froth Flotation Process. The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use

· Therefore, the life cycle of water used for flotation should be considered in the designing and operation of flotation plants. Once the most important step is identified in the circuit, e.g., the key points in enhancing water use efficiently, corresponding methods can be derived for water managements.

· Flotation. According to the difference in physicochemical properties of mineral particle surfaces, flotation is the method that selectively enriches the target minerals in the pulp at the gas-liquid interface and separates them from the pulp, thus realizing the mineral separation. It is also known as floating separation.
