Jan 01, 2016 1. Introduction. The association of gold and copper mineralization in commercially viable ore is a common occurrence. At one end of the spectrum is the predominantly copper ore, which contains levels of gold mineralization. This would be uneconomic to mine for its gold content, but the gold provides a significant opportunity value.

By 1978, when the large porphyry copper mines closed, the Robinson mine area deposits had produced nearly 360 million tons of 1% copper ore, which included 2.7 million ounces of byproduct gold. In 1994, the geologic resource of the deposit was reported as 252 million tons of
Many gold mines can remain profitable even if the ore contains less than 0.1 ounces of gold in a ton of rock. Figure 9.16 shows an example of gold ore from Greenland. The gold flakes are small the entire photo is less than 2 cm across. The market for metals can be extremely volatile.

copper mines within the RTB Company ranked among the highest-grade copper mines (on average 5 6 % Cu in the ore). At the end of the century, the average Cu content in the RTB Bor mines fell to less than 0.4 %, which is illustrated by Fig. 1. Consequently, it is now ranked among lower-grade copper mines in the world 9.
