9 Ore Deposits and Economic Minerals – Mineralogy

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.

In this case, feldspar concentration is 1.89%, mica concentration is 2.56%, and quartz concentration is 5.51%. That is, when the weight ratio of pyrite, feldspar, mica, and quartz is 10:4:5:11, pyrite has the least pollution to the environment. However, this situation is the most unfavorable for the pretreatment of refractory gold ore.
