COAL FLOTATION - Mineral Processing Metallurgy

May 23, 2017  Flotation is carried out at low solids, usually under 10% dilution. In the U. S. on bituminous coal the trend is toward open type No. 30 “Sub-A” Cells, single overflow, and with supercharging. Flows of dilute pulp up to 1500 GPM are effectively treated with excellent results through a single 4-cell

What Are Column Flotation Cells?

Feb 06, 2019  The other type of flotation cells is a column cell. Column cells are tall round tanks that use compressed air to create air bubbles via spargers or cavitation tubes. These cells are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Mixing is achieved by the turbulence provided by the rising bubbles.

Jul 18, 2018  The coarser size fraction (+0.5 mm) should not be allowed to go along with the feed to the flotation cells as it creates trouble in the flotation circuit. The optimum size range for feed coal to flotation is 0.3 mm (48 mesh) to 0.015 mm (200 mesh). Thus, it is preferable to deslime the coal by hydrocyclone and the -0.015 mm fraction may be ...

Flotation Circuits. Flotation circuits are typically comprised of rougher, scavenger and cleaner flotation banks. Rougher and scavenger banks are focused on recovery and thus provide maximum residence time. Rougher banks can be large with the number of cells being 5 or greater. Scavenger cells are the last line of defense for avoiding losses.
