What is the primary method of extracting copper from its sulfide ores?

Step 1: Identify the copper sulfide ore, which is the raw material containing copper.
Step 2: Crush the ore into small pieces to increase the surface area for the extraction process.
Step 3: Heat the crushed ore in a furnace at high temperatures.
Step 4: Add a reducing agent, such as carbon, to the heated ore. This helps to remove sulfur from the ore.
Step 5: As the ore is heated, the copper sulfide reacts with the reducing agent, producing molten copper and other byproducts.
Step 6: Collect the molten copper, which can then be cooled and solidified for further use.
