Copper mining and processing operations at our Queensland Metals business involves a three-step process. Firstly, we mine the ore at our two underground copper mines at Mount Isa Mines and Ernest Henry Mining. Secondly, we smelt the ore into copper anode at our Mount Isa Mines copper smelter. This 99.7% pure copper anode is transported by rail

When deciding to engage in copper ore processing, we need to know how is copper made by ore processing and smelting. Beneficiation is an important step for the mining and processing of ore. Get aware of the different beneficiation methods and choose the most suitable one among them, then we can get better results with lower investment.

Copper is refined from ores in the ground, either through underground or open-pit mines. Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores.

copper mines within the RTB Company ranked among the highest-grade copper mines (on average 5 – 6 % Cu in the ore). At the end of the century, the average Cu content in the RTB Bor mines fell to less than 0.4 %, which is illustrated by Fig. 1. Consequently, it is now ranked among lower-grade copper mines in the world [9].
