Smithsonite. Sample of the mineral smithsonite (zinc carbonate), an ore of zinc. It is a typical sedimentary precipitate produced by the action of waters rich in zinc sulphate on carbonate rocks. When pure, it is white. The presence of copper impurities turns the mineral green-blue, while traces of cadmium result in a bright yellow colour. | |
