    AchievementsGeologyUsesLocationsOperationMissionThe zinc mining process is conducted primarily underground, with more than 80 percent of all zinc extracted beneath the Earths surface. Eight percent of zinc is mined in open pits, with the remaining 12 percent being mined through both methods. Once its removed from the earth, the concentrate is roasted at a temperature of 950 degrees Celsius, causing zinc, sulfur and iron oxidization. After the zinc and iron oxides are reduced to powder form and leached with diluted sulfuric acid, the solution is neutralized an

  • How zinc is made material, used, parts, components

    BackgroundThe Manufacturing ProcessQuality ControlThe FutureMining1. 1 Zinc ores are dug from underground mines using conventional blasting, drilling, and hauling techniques. The ores occur as zinc sulfide (also called sphalerite), zinc carbonate (smithsonite), zinc silicate (calimine), and in compounds of manganese and iron (franklinite). Zinc ore is sometimes mined Froth flotation1. 2 Zinc can be produced by a process called froth flotation, which is also used for reduction of copper and lead ores. This process involves grinding the zinc ore to a fine powder, mixing it with water, pine oil, and flotation chemicals, and then agitating the mixture to "float" the zinc to the surface. A variety of cheFiltering1. 3 The froth is filtered to remove the water and liquid oils. The paste-like remainder is mixed with lime and sent to a furnace. The furnace roasts the mixture at 2500°F (1371°C), which fuses the minerals into solid chunks called sinter. At this point, the material has been completely converted to zinc oxide.See more on madehow
