9 Ore Deposits and Economic Minerals – Mineralogy
Ores and ore minerals vary greatly in quality. Ideal ores contain ore minerals. Such ores do not exist, but some come close. Ideal ore minerals contain of the commodity of interest. Native copper, for example, is an ideal copper ore mineral. Ideal ore minerals are, however, uncommon. The most commonly mined ores are not ideal.
Quartz Mining and Extraction | Quartz Mining Processing
