DESCRIPTION: A flowsheet of Coarse gravity concentration followed by flotation circuit.
ORE TREATED: On ores wherein base metals or gold bearing pyrite free at a coarse size.
ADVANTAGES: This flowsheet illustrates the application of a concentrating table in the ball mill classifier circuit, followed by flotation of the classifier overflow at a finer mesh. Where base metal minerals free at a coarse size, it may be desirable to remove as high a percentage as possible by gravity concentration.
PROCESSING COMMENTS: In the great majority of cases, the use of the Unit Flash Flotation Cell or Mineral Jig has given better results and should be considered in preference to this flowsheet.
