The interfacial interactions between algal cells, collector, and bubbles are key to efficient microalgae foam flotation, which is related to the effective regulation of the interface conditions to achieve efficient and low-cost microalgae ...
Read MoreTo 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.

Read MoreThe 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.
