Japan Urgently Needs to Increase Recovery of Rare Metal

Indium is usually recovered by first pulverizing LCD panels in glass cullets and smelting them with hydrochloric acid. Impurities are then eliminated by the alignment extract method, during which other elements are removed from the deflection plates and alignment films used in LCD panels.

Gallium Wikipedia

Gallium is a chemical element with symbol Ga and atomic number 31. It is in group 13 of the periodic table, and thus has similarities to the other metals of the group, aluminium, indium, and thallium.Gallium does not occur as a free element in nature, but as gallium(III) compounds in trace amounts in zinc ores and in bauxite. Elemental gallium is a soft, silvery blue metal at standard
