The copper nickel and other metals are tied up in high sulphur content ores and in order to recover the metals the sulphur needs to be separated from the metals The early methods to do this were effective but devastating to the environment and probably to the health of workers Prior to 1929 gigantic piles of cordwood up to 2km long see Figure 5 were laid out and ore

Copper Geoscience Australia

At some Australian mines the copper is leached from the ore to produce a copper rich solution which is later treated to recover the copper metal The ore is first broken and set out on leach pads where it is dissolved by a sulfuric acid solution to leach out the copper The copper rich solution is then pumped to the solvent extraction plant to separate the copper as a copper

Metal Deposits Physical Geology 2nd Edition

Looking at copper for example we can see that while average rock has around 40 ppm parts per million of copper a grade of around 10 000 ppm or 1% is necessary to make a viable copper deposit In other words copper ore has about 250 times as much copper as typical rock For the other elements in the list the concentration factors are much higher For gold it s

Geology and mining — MineFacts

Geology is the study of the Earth and its component parts What does our bedrock look like and how do we best extractCopper ore with a content of per cent is probably not worth extracting if it lies at a depth of 1000 m but can be interesting if it is at the surface This is because extraction costs are lower in an open pit at
