Smelting is a form of extractive Metallurgy; its main use is to produce a metal from its ore. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gasses or slag and leaving just the metal behind. The reducing agent is commonly a source of carbon such as coke, or in earlier times charcoal. The carbon (or carbon monoxide derived from it) removes oxygen from the ore, leaving behind elemental metal. The carbon is thus oxidized in two stages, producing first carbon monoxide and then carbon dioxide. As most ores are impure, it is often necessary to use flux, such as limestone, to remove the accompanying rock gangue as slag.
However, the temperature (smelting point according to the question) for this reaction will vary for each metal.

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 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.
What does the purpose of smelting?
The purpose of smelting is to extract metal from ore by heating it to high temperatures in a furnace. This process separates the desired metal from impurities, allowing for the creation of pure metal products for various uses, such as construction, manufacturing, and technology.
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.
The process in which an ore is melted to separate the useful metal form other elements is?
The process of melting an ore to separate the useful metal from other elements is called smelting. During smelting, the ore is heated to high temperatures in a furnace, causing the metal to separate and collect at the bottom while the impurities rise to the top as slag.

What is the word for changing metal to gold?
smelting ? Alchemy!
Why metal piece is not fused in slag?
A metal piece is not fused in slag primarily because of differences in melting points and chemical properties. Slag, which is a byproduct of metal smelting, consists of oxides and other compounds that can encapsulate impurities but typically have a lower melting point than the metal itself. Additionally, the metal may not react chemically with the slag components, preventing fusion. Consequently, the metal remains separate and can be extracted from the slag after the smelting process.

What metals can be extracted smelting?
Smelting is primarily used to extract metals from their ores, with common examples including iron, copper, lead, and zinc. During the smelting process, metal ores are heated to high temperatures in the presence of a reducing agent, often carbon, which helps separate the metal from its ore. Other metals that can be extracted through smelting include nickel, tin, and silver. The choice of metal depends on the specific ore and the smelting technique employed.
A process to melt and separate unwanted materials from a metal?
smelting.
What is meant by - smelting?
Smelting is the process which ore goes through so that a metal can be extracted from it. It involves heating the rock to very high temperatures. Copper, for instance, can be extracted at temperatures of about 1200 °C.Actually, smelting is a process when a metal which is more reactive than copper needs to be extracted. For example, zinc is more reactive than copper so it has to be extracted smelting. It can be extracted by heating its ore with charcoal aka smelting.--different person
