Feb 26, 2017 Froth Flotation Method for Sulphide Ores. The floatation process at present finds its greatest scope in recovery from ores whose predominant values are associated both chemically and physically with sulphides. The major proportion of the present day worlds base metal production is procured by the flotation process. Since its inception flotation has been responsible for a vast improvement in the metallurgy of sulphide ores.

process control of flotation systems have been reported, particularly in the platinum industry. One of the reasons is that to date froth features could not be related to key performance indicators such as froth grade and recovery. The research focus areas have been the use of froth appearance to detect predefined operational states Moolman et al.

Background Froth flotation is the follow-on operation, after comminution and classification, in the process of liberating and separating minerals by exploiting the differences in physical properties of the different minerals that make up an ore. Froth flotation is achieved when particles are separated based on their surface potential.
