Froth Flotation (Sulphide & Oxide) Kindly send few such papers on column flotation. I too am fond of column flotation. I spent 4 years on industrial column to develop an innovative design for a column for Zn cleaning circuit to reduce Silica from 6% to 3% so as to make acceptable to SMELTER. 80000 MT OF Zn concentrate was rejected by smelter for having high silica.

11.1.4 Floating-Point Types (Approximate Value) - FLOAT, DOUBLE For example, a column defined as FLOAT(7,4) will look like -999.9999 when displayed. MySQL performs rounding when storing values, so if you insert 999.00009 into a FLOAT(7,4) column, the approximate result is 999.0001.

Microcel™ Flotation Column Modelling: Coal Preparation: Vol ... Apr 27, 2007 · A full-scale Microcel™ flotation column was trialled at the BHP Coal Peak Downs Mine and Saraji Mine coal preparation plants for the treatment of 0.5 mm × 0 (−500 μm) coal. By using deep froths and counter-current froth washing, the Microcel™ columns have been demonstrated to achieve substantially lower product ash compared to conventional flotation cells when treating slimes fractions. Author: A. E. Lahey, C. J. Clarkson, I. BrakePublish Year: 1998Column Flotation Cells - Mineral Processing & Metallurgy Column flotation cells, like mechanical cells, are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Instead, mixing is achieved by the turbulence provided by the rising bubbles. Columns are mostly used to produce final grade concentrates because they are capable of high selectivity.
