flotation process, in mineral treatment and mining, process for concentrating the metal bearing mineral in an ore. Crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents. When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a froth on the surface.
Nov 01, 2011· Mineral Flotation. Posted by Matrix on 1st November 2011. Flotation has been at the heart of the mineral processing industry for over 100 years, addressing the sulphide problem of the early 1900s, and continues to provide one of the most important tools in mineral separation today. The realisation of the effect of a minerals hydrophobicity on flotation all those years ago has allowed us to treat oxides, sulphides and carbonates, coals and industrial minerals
density is too low, minerals are washed out of the cell before they have a chance to float. If the density is too high, the agitators will be unable to disperse enough air into the cell and the slurry will be difficult to keep in suspension. Flotation agitators have three basic functions: to keep sand in suspension, to disperse air as discreteFile Size: 489KB
The following steps are followed, following grinding to liberate the mineral particles: Reagent conditioning to achieve hydrophobic surface charges on the desired particles Collection and upward transport by bubbles in an intimate contact with air or nitrogen Formation of a
