Minerals in Modern Technology — Google Arts & Culture
Solar Panels Solar panels have become a very common modern technology in Australia. The panels convert light from the Sun into electricity. Most solar panels are made of the element silicon (c-Si) but new thinner, flexible panels, like copper-indium-gallium-(di)selenide (CIGS), cadmium telluride (CdTe) and dye-sensitised solar cells, use rarer minerals in their manufacture.

ALUMINA PRODUCTION. Bauxite is crushed, dried and ground in special mills where it is mixed with a small amount of water. This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in bauxites. The ore is loaded into autoclaves and treated with lime–caustic soda.
