Geology of Copper Properties, Mining, and Formation of

When mixed in with other ores, copper is not usually found in great abundance. Until the development of the modern copper mining process, it was typically a byproduct of mining for other metals. The deposits that contain the largest quantities of copper are called porphyry deposits, and the process of extracting it usually involves drilling an open pit into a layer of sedimentary rock.

OSNACA Mathematical Techniques OSNACA Ore Samples

For elements with relatively high average crustal abundance (e.g., Cu (29 ppm) and especially Fe (56,000 ppm)) log 10 measurements unduly restrict the log normalised score that these elements can reach (Fig. 2). Even for an abundance of 100% Fe, the log 10 score is only 1.3. Therefore, for elements with ACA greater than 1 ppm, the base used to calculate the log normalised score has been
