flotation column for mineral processing

Column Flotation Technology CSIR-NML

The column flotation technology is a new mineral beneficiation method developed on strong scientific principles for processing of fine low grade ores and minerals. The merits of the technology includes improved metallurgical performance in terms of grade and recovery, effective cleaning of froths, small foot print, low capital investment, less operation and maintenance costs with user friendly controls.

2021-7-3  The key factor will not be the flotation cell used, but rather the chemical conditioning that you use to make the chrysocolla hydrophobic. The mineral has variable flotation properties since it has an indeterminate copper concentration that ranges anywhere from about 20-35% Cu. Recoveries in conventional flotation tend to be unspectacular.

2014-7-16  Power costs can be 40 50% lower than an equivalent mechanical flotation circuit. Using column flotation it is possible to simplify the process by replacing two to three cleaner stages and associated transfer pumps with a single column producing final concentrate. Column cells have very low maintenance requirements and low inventory requirements.
