Comment by RazerQuick If you're trying to get a lot of copper ore quick at a high level your bags will fill up fast. I ran the Mulgore route for 100 copper dont forget that copper ore only stacks in 10, so I kept stopping at the Venture Co. Mines Cave to smelt ore into bars (stacks in 20) to save space and time.Hope this helps anyone else trying to …
Mining consumes large quantities of water; the copper mining industry alone withdrew over 1.3 billion m 3 of water in 2006 (Gunson et al., 2010b). On a global scale, however, mine water use accounts for a small portion of overall water use. Even in relatively dry, mining-intensive countries like Australia, Chile, and South Africa, mine …

The cost of copper, in those days, was very great. In 1714 cake copper, unrefined, fetched £100 per ton, and plates as they came from the battery works cost £140 to £150 per ton. In 1694 Swedish copper, which was then regarded as high quality, cost £168 per ton. These figures, currency for currency, far exceed modern prices.
This is done using a special machine called a drilling rig, which rotates a drill bit to break through layers of rock and soil. The drill bit is attached to a long metal pipe called a drill string, which helps to carry drilling fluids down to the bit and bring up pieces of rock and soil as the hole gets deeper. Drilling allows oil and gas ...
In two case studies that he currently focuses on — the ndida and Los Pelambres copper mines — the mining companies have expanded their desalination objectives in order to reduce extraction from key continental sources. This seems to be due to a variety of factors. For one thing, in 2022, Chile's water code was reformed to …
