The recovery of sericite in flotation concentrates: Mineral ...

Sericite is a fine grained muscovite mica, which is widely distributed in nature. It commonly occurs in many base metal ores, where it can become a major diluent in the concentrates produced from these ores, as well as in igneous rocks. It can be strongly recovered in flotation froths under circumstances where it is both wanted and unwanted.

Leachox™ Process for flotation concentrates | Maelgwyn ...

Whilst the installation is similar to that used for pre-oxidation or Aachen assisted leaching in the Leachox process the flotation concentrate is pumped through the reactor multiple times perhaps as many as 30 passes in contrast to 1-2 passes for the pre-oxidation role .Depending upon the mineralogy ultrafine grinding of the flotation concentrate may be required prior to cyanidation

Processing Spodumene by Froth Flotation for Lithium Extraction

Spodumene theoretically contains 8.03% Li2O and therefore the production of this mineral is greatly increasing because of the expanded use of lithium in the manufacture of high temperature insoluble lubricants, ceramics, pyrotechnics, non-ferrous welding fluxes, air purifying agents, and hydrogen isotopes. Extracting Lithium from its Ore The problems of spodumene mineral dressing depend on the ...
