Questions & Step-by-Step Solutions

In the context of metallurgy, what is the primary purpose of roasting sulfide ores?
  • Step 1: Take the sulfide ore, which contains metal in a combined form with sulfur.
  • Step 2: Heat the sulfide ore in the presence of oxygen (usually in a furnace).
  • Step 3: During heating, a chemical reaction occurs that converts the sulfide into metal oxides.
  • Step 4: The resulting metal oxides can then be further processed to extract the pure metal.
