May 01, 2006 While neither column sparging system matches the performance of the OK-50 mechanical cell, a difference of 1.5 mm in the d 32 values exists between the Microcel and jetting-type air sparging systems. Under the same frother addition rates the Microcel generated an average d 32 of 1.9 mm while the jetting-type system averaged a d 32 value of 3.4 ...
Feb 28, 2016 Based on these investigations messrs J.D. McKay and D.G. Foot, Jr. developed the patented Turbo Air external bubble generation. Because of its design, this sparger is capable of achieving higher air hold ups and greater bubble size control which have generally resulted in higher mineral recoveries at lower gas flowrates.
