Froth flotation - WikipediaIn the mining industry, the plants where flotation is undertaken to concentrate ore are generally known as concentrators or mills. For froth flotation, the ground ore is mixed with water to form a slurry and the desired mineral is rendered hydrophobic by the addition of a surfactant or collector chemical (although some mineral.column flotation concentrators,fuzzy-based modeling and control of an industrial flotation columnIn the present investigation, a fuzzy model was developed to simulate the relationship between the process conditions (i.e., gas velocity, slurry solids %, frother dosage, and frother type) and the metallurgical performance of an industrial flotation column in a copper concentrator in Iran. Afterwards, an intelligent model–based.

Gas dispersion in column flotation and its effect on recovery and grade

This paper reports the results of industrial test work performed in flotation columns of seven concentrators of Pen˜oles Group (México) on the relationship between gas dispersion parameters, namely gas rate (Jg between 0?5 and 3?5 cm s21), gas hold-up (eg between 3?3 and 19?4%), average bubble size (d32 between.

fuzzy-based modeling and control of an industrial flotation column

In the present investigation, a fuzzy model was developed to simulate the relationship between the process conditions (i.e., gas velocity, slurry solids %, frother dosage, and frother type) and the metallurgical performance of an industrial flotation column in a copper concentrator in Iran. Afterwards, an intelligent model–based.
