challenges faced in mining and extraction of copper
Challenges and new insights for exploitation of deep underground metal
The safe and effective exploitation of deep metal mineral resources is facing a series of engineering challenges. Compared with shallow mining, deep mining encounters a special geological environment of high stress, high temperature, and high water pressure as well as more severe engineering disturbance induced by mining activities [9].

Mining – Environmental and Social Challenges
The mining process consists of 4 major stages: 1. Exploration – determining sites which contain valuable deposits of the material to be mined and then determining the extent of the valuable material. 2. Development – building the mine of which there are several design options chosen based on the nature of the deposit. 3.

Lead processing
Lead processing - Mining, Concentrating, Refining: Once the ore is removed from veins (narrow channels) or lodes (roughly spherical deposits) in the Earth, usually at depths of about 60 metres, the ore is treated at concentrating mills. Here the ore is finely crushed, sometimes to particle diameters of less than 0.1 millimetre (0.004 inch), and then treated …

Full article: World mineral loss and possibility to increase ore
The total mineral loss in mining and mineral processing is on average 37.2% of the actual production (metal content or final mine product) as the ore recovery ratio is 81% in mining and 90% in mineral processing. This corresponds to a vast amount of mineral loss for the world every year.

Australia's yet to capitalise on its rich deposits of critical minerals
That's where Australia can help. We have the world's largest supply of four critical minerals: nickel, rutile, tantalum and zircon. We're also in the top five for cobalt, lithium, copper, antimony, niobium and vanadium. Even better, many of these minerals can be produced as a side benefit of mining copper, aluminium-containing bauxite ...
