Froth flotation is a method of mineral separation in fluid which relies on the difference between the chemical composition of minerals compared to gangue. Flotation cells (tanks of fluid) are aerated to produce bubbles.
Froth flotation is a commonly employed process for concentrating minerals from ores. In a flotation process, the ore is crushed and wet ground to obtain a pulp. A frothing agent, usually employed with a collecting agent, is added to the ore to assist in separating valuable minerals from the undesired or gangue portions of the ore in subsequent .
This real time analyser and controller is designed for stabilizing the flotation levels (froth depth) in the flotation circuits used in the mining industry. This goal is achieved by controlling the aeration rate and the reagents addition. Furthermore the temperature of the reagents is stabilized.
