WebScience Chemistry Iron ore is impure, Fe2O3. When Fe2O3 is heated with an excess of carbon (coke), metallic iron and carbon monoxide gas are produced. From a sample of ore weighing QA 938 kg, 523 kg of pure iron is obtained. What is the mass percent Fe2O3, by mass, in the ore sample, assuming that none of the impurities contain Fe. WebFIRE ASSAY. Fire assaying is a fusion process used to determine the concentration of metal in ore by placing samples and a combination of fluxes into a high temperature furnace. When heated metal content is separated from sample compounds and used to gauge the recovery of precious metals. Fire and Metallic Fire Assay are typically …
