Jan 11, · The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores. The metallic contents of the minerals are recovered from the concentrates in a subsequent series of metallurgical

Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.

The froth flotation process is commonly employed for the selective separation of a mineral species from a liquidsolid suspension of both valuable and unwanted gangue mineral particles. The valuable mineral species (which needs to be separated) is rendered hydrophobic by controlling its surface chemistry to provide the potential conditions for the attachment of the particles to air bubbles.

An innovative selfdesigned medium was packed in a benchscale flotation column to study its influence on the flotation recovery of bauxite. Computational fluid dynamics (CFD) simulation was conducted to reveal the impact of the packing medium on the turbulent characteristics of collection zone in the column. Simulation results show that multilayer packing of the medium divides the collection
