Froth Flotation an overview ScienceDirect Topics

Abstract. Froth flotation is a separation process used in a number of applications worldwide. Recycled paper deinking, water purification, bitumen recovery from oil sands and, in particular, mineral separation, benefit from this industrial operation. The complex phenomena occurring within the froth phase of a flotation cell, however, are not

Froth flotation of xenotime NASA/ADS

Abstract. Froth flotation as a fundamental method for processing complex minerals is commonly applied to the surface chemistry and beneficiation of rare-earth-bearing minerals. This is due to the fact that it is possible to process a wide range of fine particle sizes and the process can be tailored to the unique mineralogy of a given deposit.

Abstract Froth flotation has been one of the most important and widely used methods to concentrate minerals since its introduction over a hundred years ago. Over the last few decades, in order to process more mineral while reducing capital costs, flotation equipment has become exponentially larger. The increase in tank volume, however, has brought new challenges in the operation and design of

Abstract. The pulp and froth zones are the main components of froth flotation as it defines both quality of the end product and overall efficiency. The importance of the properties of the two zones, which include pulp hydrodynamics, froth bubble coalescence rate, water overflow rate, air recovery, etc., is being increasingly recognized.
