Anvil Mining Limited (TSX, ASX: AVM), a copper producer whose shares are traded on the Toronto Stock Exchange, has produced copper cathode at its flagship Kinsevere Stage II Solvent Extraction and Electro-Winning
Highlights for Stage 2 solvent extraction electro-winning
This includes initial mining near the surface for copper oxide and beneficiation by means of leaching and electro-winning
. This will enable Craton to produce copper metal, rather than a concentrate which needs to be exported.
The Project is designed to process 12Mt/a of oxide ore by crushing, vat leaching, solvent extraction and electro-winning
to produce up to 52,000 t/a of cathode copper.
When Avmin bought the Chambishi plant it comprised a roaster, leaching vessels, copper electro-winning
and an acid plant.
In addition to the HMS operation, Tiger's Stage 2 solvent-extraction electro-winning
(SXEW) plant at Kipoi is on schedule to commence production of copper cathode in Q2 2014.
