This copper, now 99.9%+ Cu, is of essentially the same purity as fire-refined copper produced from ore. Small samples are taken from the molten copper periodically to check the progress of the refining operation. Samples are transferred quickly, often via pneumatic tubes, to a fast-reading spectrograph that monitors the metal's impurity content ...

Vein Mineral Deposits - Mineral Processing & Metallurgy
Vein Mineral Deposits includes a considerable variety of ore deposits formed under various conditions by the concentration of the ore from the molten rock in process of cooling, and its subsequent deposition in fissures and joints, crevices, and pores; or the accompanying solvents make room for the ore by dissolving the rock and carrying it away.
Copper | KGHM Corporate Website
With an average ore grade of 1.6% copper, KGHM produces approximately 700 thousand tonnes of red metal. The core products of KGHM are electrolytic copper cathodes with minimum 99.99% of copper content. What is more, the company processes ore to obtain concentrate and metallic copper in the form of wire rod, Cu-OFE and Cu-Ag wire and granules.

Calculating stripping ratios. At their most basic, strip ratios can be calculated by dividing overburden thickness by ore thickness. For example, an overburden thickness of …
Copper demand, supply, and associated energy use to 2050 ...
Copper demand is met by the supply from secondary sources and primary sources. The required future supply of copper from primary sources (demand minus secondary supply) is shown in Fig. 3(c), and from secondary sources in Fig. 3(d). These results assume that no limitations exist on copper ore deposits. However, such limitations do exist.
What is a Porphyry Copper Deposit?
center of the system. The copper ores are characterized by the following sulfide-bearing minerals: chalcopyrite, bornite and molybdenite (minor) with minor to moderate amounts of pyrite. These ore bodies are very large, generally containing from 100 million to several billion tons of copper ore with a copper content of 0.2% to 2.0%.

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.
