What is the relationship between collector and frother


The effect of collector and frother is not isolated. In addition to some agents having two properties, they also influence each other. Flotation is a method of processing ores by using the difference between hydrophobic and hydrophilic on the surface of minerals. In the operation of flotation machine, flotation reagents are usually used to increase or decrease the water property of mineral surface, adjust and control the flotation behavior of minerals, so as to obtain better operation indexes of flotation machine.


In flotation machine, frothing agent not only affects the quantity and quality of mineral bubbles, but also affects the contact between mineral particles, and it can promote the separation of hydrophobic mineral particles and hydrophilic mineral particles in the foam layer. After many mineral processing tests and practical production data, it can be seen that the performance will directly affect the flotation operation indicators, thus affecting the mine dressing enterprises. The economic benefit and resource utilization rate are also discussed.


When the amount of collector is constant, the dosage of other agents is also constant, and the increase of the amount of foaming agent can increase the yield of flotation froth. If the inhibition is not very strong, sometimes a little increase in the amount of foaming agent can make the inhibited minerals float. The amount of foaming agent is not enough, the bubbles formed are weak, the amount of foam is insufficient, and the recovery rate is affected. However, when the dosage is too large, the foam may be too stable, or the amount of foam is too high, which will affect the selectivity of flotation machine selection process, and even the so-called "running slot" phenomenon that bubbles emerge from the flotation tank. The selectivity of flotation process is often achieved under the condition of correct use of frother.
