ViviRoasting is a process of heating an ore in the presence of oxygen to remove volatile impurities and convert the ore into an oxide, while smelting involves heating the ore with reducing agents such as carbon to extract the metal from its ore. Roasting is usually done for sulfide ores, while smelting is done for oxide ores. In roasting, the product is an oxide, whereas in smelting, the product is the pure metal.

What is the difference between roasting and smelting?
Roasting is a process where ore is heated in the presence of oxygen to remove sulfur, arsenic, and other volatile impurities. Smelting is a process that involves melting the ore to extract metal from it, usually using a reducing agent like charcoal or coke. Roasting is more focused on removing impurities, while smelting is about extracting the desired metal.
What is the difference between smelting and refining?
Smelting is the process of extracting metal from ore by heating it with a reducing agent, while refining refines the metal further to improve its quality and remove impurities. Smelting is the initial step in metal production, while refining is a secondary process to purify the metal for specific applications.
What is the difference between metal melting and metal smelting?
Metal melting is the process of heating a metal until it turns into a liquid state, typically for casting or shaping purposes. Metal smelting, on the other hand, is the process of extracting metal from its ore through heating and chemical reactions, usually involving the removal of impurities to obtain pure metal.
What is difference between calcination and roasting?
Calcination is a process that involves heating a substance strongly to drive off carbon dioxide or water, usually to obtain a purer product or to convert it into a more reactive form. Roasting, on the other hand, is a process that involves heating a substance strongly in the presence of air to oxidize it, usually to remove impurities or improve its physical and chemical properties. In summary, calcination involves driving off volatile components, while roasting involves oxidizing a substance.
What is smelting waste called?
Smelting waste is often referred to as slag. Slag is the byproduct generated during the smelting process when impurities are separated from the metal ore.
