    Rosedale East Mines calcining kilns and iron mines, 280m

    The carbonate ores require calcining (roasting) to drive off carbon dioxide, converting the ore into an oxide before it can be smelted to produce iron or steel. Calcining also improves the ore for smelting by driving off water and other volatile substances, and by breaking the ore into smaller fragments. The earliest and simplest method of calcining was to pile ore and fuel into a heap known

    Roasting is a process of heating a sulfide 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 has already been partially purified, e.g. by froth flotation.

    Question of the Week: What is Reduction Roasting?

    Reduction roasting is the removal of oxygen from a component of an ore, usually through the use of Carbon Monoxide (CO).
