Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of pure copper called cathodes which will ultimately be made into products for everyday most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively due to the different
Signed into law by Ulysses S Grant the General Mining Law or Hard Rock Mining Act of 1872 was designed to encourage settlement in the west and promote the small scale pickand shovel mining of hardrock minerals such as gold It is still in effect and applies to more than 270 million acres of federal land nearly 25 of all the land in the
Surface mining is suitable for large low grade ore deposits which occur below a thin layer of rock or alluvial deposits found in sand and riverbeds Underground mining is used for small high grade deposits covered with a thick overburden soil and rock above the ore or for deep and sloping deposits.
Rock or Solid Mine Waste Open pit mining has several stages of waste First to access the actual seams or veins of ore the top layers of rock or overburden must be removed Once the overburden has been removed the seams can be extracted When extracting the seams there is additional waste rock that must be separated from the ore.

Apr 25 2019 1 2 3 Geothermal wells are drilled deep into the ground in order to tap into the heat radiating from the Earth s core and transform it into electricity However one remaining challenge associated with drilling deep geothermal wells is the presence of hard rocks such as granite that slow down the process and wear down drill bits.
Comprehensive surface exploration by past explorers but very limited drill testing mean this near surface porphyry target is poorly explored Encouraging granite hosted intercepts including 17m at Cu Pb Zn 84gpt Ag from 108m
