Smelting involves more than just melting the metal out of its ore. Most ores are a chemical compound of the metal with other elements, such as oxygen (as an oxide), sulfur (as a sulfide) or carbon and oxygen together (as a carbonate).
Smelting is a method of producing refined goods in Minecraft, also known as melting, baking, cooking, burning, drying, or producing. It has the same idea as crafting; one must put in acceptable ingredients, and a corresponding output will be given.  Large scale iron ore smelting has been carried out in numerous types of blast furnaces since the industrial revolution, with the basic ingredients of coke, iron ore and limestone remaining unchanged, being loaded into the blast furnace from where the molten iron is tapped into molds. slide 1 of 6. Limestone is used as a flux to separate the gangue from the molten iron ore, the accumulated slag and the molten iron being tapped from two tap-holes at the bottom of the furnace. Smelting is a process for extracting usable ore from mixed deposits where people find ore bound with other metals, rock, and extraneous material. It is very unusual to find deposits of pure ore and this method allows people to separate out useful metals. In the smelting process, people heat the material with an agent to trigger a chemical reaction. Although people often refer to smelting as another form of melting, simply melting material is not enough. Smelting, is a form of extractive metallurgy. The main use of smelting is to produce a metal from its ore. This includes iron extraction (for the production of steel) from iron ore, and copper extraction and other base metals from their ores. Submit. · just now. Report Abuse. Smelting is a process by which a metal is obtained, either as the element or as a simple compound, from its ore by heating beyond the melting point, ordinarily in the presence of oxidizing agents, such as air, or reducing agents, such as coke. Chemical reduction, or smelting, is a form of extractive metallurgy. The main use of smelting is to produce a metal from its ore. This includes iron extraction (for the production of steel) from iron ore, and copper extraction and other base metals from their ores. Submit. · just now. Report Abuse. Smelting is a process by which a metal is obtained, either as the element or as a simple compound, from its ore by heating beyond the melting point, ordinarily in the presence of oxidizing agents, such as air, or reducing agents, such as coke. Smelting is a form of extractive metallurgy; its main use is to produce a base metal from its ore. This includes production of silver, iron, copper and other base metals from their ores. The oxides, in turn, are smelted into the metal. Carbon monoxide was (and is) the reducing agent of choice for smelting. It is easily produced during the heating process, and as a gas comes into intimate contact with the ore. In the Old World, humans learned to smelt metals in prehistoric times, more than 8000 years ago Smelting. the process of converting ores, usually metal ores, in smelting furnaces to produce a final product in molten form. Blast-furnace smelting is used in metallurgy for extracting metals from ores. Smelting processes vary in detail depending on the nature of the ore and the metal involved, but they are typified in the use of the blast furnace blast furnace,structure used chiefly in smelting. Smelting involves more than just melting the metal out of its ore. Most ores are a chemical compound of the metal with other elements, such as oxygen (as an oxide), sulfur (as a sulfide) or carbon and oxygen together (as a carbonate). To produce the metal, these compounds have to undergo a chemical reaction. The oxides, in turn, are smelted into the metal. Carbon monoxide was (and is) the reducing agent of choice for smelting. It is easily produced during the heating process, and as a gas comes into intimate contact with the ore.
