Smelting is a process used to extract metal from its ore by heating and melting. The first step involves crushing the ore and mixing it with a reducing agent, typically carbon in the form of coke. This mixture is then heated in a furnace, where the carbon reacts with the ore, reducing it to metal and releasing impurities as slag. Finally, the molten metal is collected and cooled to form solid metal, while the slag is removed for disposal or recycling.
