However, it is unlikely that more coal will be mined and combusted to extract more germanium from ash. In addition, it is also unlikely that more copper and zinc ore will be mined to extract cadmium, indium, selenium, and tellurium, while bauxite mining will increase to extract more gallium as a by-product during alumina production.
Chemistry of Indium (Z=49)
A small amount is produced from tin production. Indium is produced from the slag of zinc production (the waste matter separated from metals during the smelting or refining of ore) using a leaching process. Leaching is an technique used to extract metals which converts them to an aqueous state. Indium is leached using (HCl) or (H_2SO_4).
