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
