The pipe is 19 km 2 in area and has an unknown depth, containing minerals like copper, phosphates, zirconium, vermiculite, mica and gold. This mine was a leader in the field of surface mining technology with the first in-pit primary crushing facility.
Process Development Considering the different gold minerals present alone or combined with the host rock, it will be necessary to discharge the unwanted material in order to increase the concentration of gold in an economically manner. This part treats the strategy of beneficiation as a combination of several processes. Joining …
Uses of Copper. Native copper was probably one of the early metals worked by ancient people. Nuggets of the metal could be found in streams in a few areas, and its properties allowed it to be easily worked without a required processing step. Copper's metallic luster attracted people's attention. Today most copper is produced from sulfide ores.
Copper and gold have similar cyanide metallurgy depending on the nature of the minerals present. The processing of gold copper and copper gold ores can be highly problematic, site specific and the process selection is dependent on ore grade, mineralogy, acid leach behaviour, cyanide chemistry, product saleability and environmental considerations.
