Selective Recovery of Graphite from Spent Potlining (SPL) …
Abstract Spent potlining (SPL) consists of the carbon cathodes (1st cut), aluminosilicate refractories, and the insulation lining of Hall–Héroult cells (2nd cut) used in aluminum smelting. SPL is classified as hazardous material due to its high content in soluble fluoride salts and the presence of cyanides. The 1st cut contains considerable …

Froth Flotation
control of a flotation process are classified as follows: The tendency of the ore to have variable physical, metallurgical, and surface properties produces significant changes in a flotation circuit. The particle size range of the flotation feed can be substantial because of ore hardness changes and changes in the operation of the grinding circuit.
