  • Roasting (metallurgy) Wikipedia

    Roasting is a process of heating of sulphide ore to a high temperature in presence of air. It is a step of the processing of certain ores. More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore

  • Copper Mining and Processing: Everything you Need to Know

    Jul 17, 2014 After the ore is crushed, it's roasted, which helps to convert sulfides to oxides. The oxides are smelted to During the Industrial Revolution, coal and steampowered machinery paved the way for a huge increase in copper production with mines smelting between 200 and 300 tons of copper ore per week.
