For non-newtonian flotation pulps, rheology is strongly dependent on the shear rate in a flotation cell [41, 42]. in several studies on pulp viscosity measurement (e.g., [19, 39, 43, 44]), apparent viscosity was obtained at 100 s −1 or 160 s −1 which are claimed to represent a typical shear rate in a mechanical flotation cell [19, 45].
And offers significant opportunities for optimization. the solution siemens has developed a process called simine hybrid flot which can satisfy these requirements. to this end, a pneumatic spray pro-cedure is combined with the column method. during the first step, the feed pulp mixed with air or gas is sprayed into the flotation cell.
Optimisation plant plant instrumentation flotation is a complex process that is affected by a multitude of factors. these factors may be inherent in the circuit design, or in how the flotation plant is operated. the floatstar suite of control modules utilises advanced process control to overcome design-

Froth flotation is a common method to extract a certain type of mineral from ore while depressing the amount of undesired minerals in the extracted concentrate. it is done by adding certain chemical reagents to selectively rendering the desired mineral hydrophobic. in a flotation cell…
Flotation level measurement techniques explainedapril . of interest in a flotation cell is how deep the froth is above the slurry, as this determines the grade of the resulting concentrate. the typical range for a froth depth is 600 mm from the top of the flotation cell, the launder, down to the slurry interface. here we are actually get price

Jun 01, 2015 flotation banks also known as rows or lines are serial arrangement of cells where the tail stream of one cell is the feed stream to the next cell down the bank. bank optimization consists of selecting the best operating conditions in each flotation cell such that the overall bank metallurgical performance is optimized.
A flotation bank is a serial arrangement of cells. how to optimally operate a bank remains a challenge. this article reviews three reported strategies: air profiling, mass-pull (froth velocity) profiling and peak air recovery (par) profiling. these are all ways of manipulating the recovery profile down a bank, which may be the property being exploited.
