Copper Flotation
A Copper Flotation Flowsheet. Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial. The flowsheet in this study illustrates a typical 3,000 ton per day operation. In general most operations of this type have two or more …

Processing Spodumene by Froth Flotation for Lithium Extraction
Fatty acid or soap flotation of spodumene is one well established recovery method, but pulverized or ground particle surface conditions generally necessitate pre-flotation treatment. This involves high density agitation with cleaning agents such as sodium silicofluoride, trisodium phosphate, or sodium sulphide with sodium hydroxide.

Phosphate Rock Properties
Properties of Phosphate Rocks. Anhydrous phosphoric acid forms prismatic crystals, which readily deliquesce in the air. As ordinarily prepared, concentrated phosphoric acid is a clear, colorless, syrupy liquid (specific gravity, 1.83), which attacks most metals and bases, forming the corresponding phosphate salts.

SELECTION OF MECHANICAL FLOTATION EQUIPMENT
A forced air flotation machine typically has stable, consistent froth flow over the lip at the top of the machine. This is because the rotor is located at the bottom of the and the tank distance of the rotor to the froth zone minimizes turbulence in the upper region, which is conducive toa stable froth zone.
