flotation process particular

Jan 11, 2016 The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores. The metallic contents of the minerals are recovered from the concentrates in a subsequent series of metallurgical operations—e.g., smelting

    Full Article. Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to remove very fine mineral particles that formerly had gone to waste in gravity concentration plants

    Sep 14, 2011 AFC, also known as stabilising control, aims to reject the effects of input disturbances (e.g. a change of ore type) and maintain the flotation process as close to steady state as possible (McKee, 1991, Laurila et al., 2002). This is generally achieved by controlling mass pull; recycle load; stream grade and/or recovery to setpoints (usually set by operators or an optimising controller), with the manipulated variables

    Flotation is known as a separation process, based on the introduction of gas bubbles as the transport medium. Suspended particulate matter, being hydrophobic or conditioned to be so, is then attach to the bubbles and moves toward the water solution surface—i.e., contrary to the direction of gravity [1,2].Different bubble generation methods exist, belonging either to the broad class of
