9 Ore Deposits and Economic Minerals – Mineralogy

These four minerals all contain weak metallic bonds. Gold, silver, and copper have further commonality in their chemical properties because they are in the same column of the periodic table. Gold and silver form a complete solid solution; we call compositions containing both gold and silver electrum. But, because copper atoms are smaller than ...

What are the metallic and non-metallic minerals found in ...

2021-7-8 · Where can metallic minerals be found? Metallic ores occur in every kind of rock and some varieties of soil. The metallic minerals are concentrated into rich masses by igneous, hydrothermal, or erosional/weathering processes. Metals such as chromium, platinum, nickel, copper, and iron can precipitate as sulfide minerals in a cooling body of magma.
