Aust Mining completes Mt Norma plant commissioning
Sydney - Friday - July 25: (RWE) - Australian Mining Investments
Ltd has completed the commissioning phase of the Mt Norma Copper
Sulphate Plant at Cloncurry, Queensland.
The company believes the commissioning phase confirms the AUM SX
Column Technology will now operate at commercial levels of production.
It has been experimenting with different-sized mediums and
loading procedures to obtain the maximum flow and loading of copper
within the circuit.
The optimum medium has been identified, resulting in a flow of
300 cubic metres p/h per column and increased copper recovery.
As a result of the additional testing of medium and loading
procedures during commissioning, the company's metallurgical team
discovered a new addition to the loading cycle which increased the
copper loading of the columns over and above the results from the pilot
plant results.
The appropriate sized medium has been ordered to load all the
columns and it is expected the plant will be operating at the full
capacity of 6000 tonnes a year production within the next six weeks.
Plans are under way for the mining of high-grade copper ore from
the Mt Norma orebody and the construction of a 50,000 tonne vat leach
pad with the view to increasing production.
