The Basics of Froth Flotation June 2015 by Chris Ralph I thought it might be worthwhile to take a look at the basics of this important mineral separation technique and how a miner can use it to recover the values out of an ore
泡沫浮选是最受欢迎的工作之一onal processes for mineral beneficiation In oremineral beneficiation froth flotation is a method by which commercially important minerals are separated from impurities and other minerals by collecting them on the surface of a froth layer
A flotation circuit’s performance is affected by both pulp and froth phase recovery And it is inherent in mining operations that manual control by operators who look at the cell surface periodically and then take action does not really maintain stable operating conditions
Flotation is the most widely used beneficiation method for fine materials and almost all ores can be separated by flotation Another important application is to reduce ash in fine coal and to remove fine pyrite from coal The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore
Flotation is used in gold mineral processing copper coal to recover fine particles typically finer than 05 mm Chemical and physical attachment of the solid particle to the bubble induced by the chemical reagents and conditioners would be a over simplified description of froth flotation
