Based on texture, ores are divided into (1) massive ores, which have a copper content of more than 3 percent and which are suitable for direct smelting (content of other metals is commercially insignificant), and (2) disseminated ores (average copper content, 1-2 percent; low copper content, 04-10 percent), which are concentrated by means of .
Commercial copper ore deposits today contain from 05 to 6 percent copper, or between 100 and 1000 times the crustal average In contrast, iron and aluminum constitute around 58 percent and 8 percent of the earth’s crust, respectively, and their commercial deposits need to be only 3 to 10 times as concentrated as the crustal aver-age
Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals, with the remainder of the ore being unwanted rock or gangue minerals, typically silicate minerals or oxide minerals for which there is often no value In some cases, tailings have been retreated to recover lost value as the technology for recovering copper has improved
