Abundance of metal ores and the concentration of metals in ores The relative abundance of metals in the crust has influenced their value and extent of use. Most abundant metal is Al (8% by weight), followed by iron (5%). Rocks that only have a sufficiently high percentage of the metal to make them economic to mine are only mined.

Indium is a typical byproduct of smelting polymetallic ores of base metals such as lead, zinc, copper and tin. In such ore concentrates the average indium content is about 70 to 200 ppm. About 95% is produced as a by-product from zinc sulphide ore. The recovery yield of indium is currently only 35%.
