Microbubble Flotation Column - 911 Metallurgist

An amorphous graphite ore was upgraded using a 5-cm diameter laboratory Microcel” column. The feed was prepared by pulverizing the run-of-mine ore in a hammer mill and wet-grinding it in a laboratory stirred ball mill for 15, 30 and 60 minutes. The mill product was diluted to 5% solids before feeding it to the column at 0.05-1.0 lpm. Metso Microcel™ sparger consists of in-line static mixers and a centrifugal pump. Tailings slurry is pumped from the base of the columnthrough the static mixers, where air and slurry are mixed under high-shear conditions to create the bubble dispersion. As the air-slurry mixture passes throgh the stationary blades located inside the mixer The made column machine which was included into the factory scheme allows to change four recleaning operations both in the regular and small-ash cycles of flotation of graphite. The column machine with ejector aerators has been accepted for use at the Taiginka Graphite Factory, Joint-Stock Company of Open Type "Uralgrafit"Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio Author: Vadim Railevich KunakbaevThe concentrator is designed to produce a graphite concentrate containing 97% Cg from an ore containing 4.39% Cg. The beneficiation process will include crushing, grinding, conventional flotation, polishing, and column flotation to achieve the concentrate.
