The carbothermic reduction process is a direct reduction of sulfides. It allows a roasting in which higher concentrations of metals such as molybdenum are obtained by using both a reducing agent (in this case, carbon C) and a sulfur scavenger, such as CaO so as to prevent air ... muffle furnace with an oxidation atmosphere. Finally, the ...

Roasting is a process of heating of sulfide ore to a high temperature in presence of air. It is a step of the processing of certain 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, by froth flotation.

Lead and zinc ores are usually found together with gold and silver. A leadzinc ore may also contain lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz. When zinc and lead sulfides are present in profitable amounts they are regarded as ore minerals. The remaining rock and minerals are called gangue. Forms of Lead and Zinc Ore
