Aug 12, 2021· → Let us consider another example of copper. Copper has various minerals i.e., copper glance (Cu 2 S), cuprite (Cu 2 O), copper pyrites (CuFeS 2), malachite (CuCO 3 Cu(OH) 2) but the ore of copper is copper pyrites (CuFeS 2) while others are not. So we can say that, "All the ores are minerals but all the minerals are not ores."
