Mining of Copper
The ore is removed from the ground in either open pit or underground mines. Underground – sinking a vertical shaft into the earth to reach the copper ore and driving horizontal tunnels into the ore. Open-pit – 90% of ore is mined using the open pit method. Ores near the surface can be quarried after removal of the surface layers
Preparation of Concentrate
The ore is enriched using a process called froth flotation. Unwanted material (called gangue) sinks to the bottom and is removed
Making of Copper Cathode
The ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW (solvent extraction/electrowinning) This method is called Hydrometallery
Quality/Sorting
Copper cathodes are known for high purity and consistent quality. Our Copper cathodes are produced using the Mount ISA electro-refining process and are 99.99% copper purity levels that meets the international quality standards BS 6017 1981 (1989) and u-Cath-1 / ASTM B-115 (1999
Inspection
CSQA is an acronym for “Cathode Surface Quality Analyzer”. Cameras scan cathodes to make images that are automatically processed by algorithms that generate metrics that indicate the quality each cathode. Depending on the quality metrics, cathodes can be classified, sorted or discarded
