The impact of water salinity and its interaction with ...

To conduct a flotation test, 1 L of water at the tested NaCl concentration was added to the flotation cell. The pH was adjusted to 8.5 using a solution of Na 2 CO 3 and the impeller was set at a speed of 1000 rpm. The coal was gradually added to the cell and sufficient time was given to wet the coal.

Experimental investigation of multi-phase hydrodynamics ...

2021-10-1  Performance of flotation cells heavily relies on their hydrodynamics inside cells and interactions among the solid, liquid and gas phases. The flotation process in conjunction with the bubble-particle interactions in three-phase flow were experimentally investigated in an industrial Wemco 56 cell.

Flotation Froth - an overview ScienceDirect Topics

Conventional flotation cells allow a small amount of clay slimes to be recovered with the water that reports to the froth product. A column cell (Fig. 19) virtually eliminates this problem by washing the clay slimes from the froth using a countercurrent flow of wash water. This feature allows columns to produce higher quality concentrate coals ...

Silicon recovery from metallurgical-grade silicon refined ...

MG-Si refined slag slurry was placed into a 1.0 L flotation cell and supplemented with water until the total volume reached 1.0 L. The impeller speed of 1992 rpm was used during the entire process of conditioning and flotation stages. Each feeding sample was first prewetted in the flotation cell for 1 min to prepare the flotation slurry.

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. The properties are depending not only on the type and concentration ...
