Quick Summary

Suspension smelting is a metallurgical process where reactions occur between gases and solids, as seen in the KIVCET process. This method, used for extracting metals like lead, differs from submerged smelting where reactions happen in a liquid. In suspension smelting, concentrated sulfide ore is injected into a furnace and ignited by a blast of oxygen. The heat generated by oxidation reduces the materials to metal. This process can produce valuable by-products like sulfuric acid from sulfurous gases. Unlike traditional methods, it doesn't require sintering or metallurgical coke and produces less gas and dust, aiding pollution control.12
