When you look at your computer screen, or the screen on your smartphone or the screen of your television set, it is a liquid crystal display (LCD). An important component of the LCD screen is indium, a rare metallic element that is processed out of zinc concentrate.
The two largest sources of indium can be found in eastern Canada (Mount Pleasant) and in Bolivia (Malku Khota). Canada’s deposits have the potential to produce 38.5 tons of indium per year, while Bolivia’s considerable mines would be able to produce 80 tons per year.
