The thermite reaction is an exothermic redox reaction between a metal and a metal oxide. (photo: Kingfisher; CC 3.0) The thermite reaction is a spectacular exothermic chemical reaction that makes an exciting chemistry demonstration. As a demonstration, the reaction illustrates the metal reactivity series, oxidation, and exothermic reaction.
>What is Smelting
What is Smelting? Smelting is the process of extracting metal from its ore, encompassing more than mere extraction from solid rock masses. Ores comprise a complex amalgamation of rock and metal, often necessitating a chemical reaction to eliminate oxygen content due to the common oxidation of metals within the ore.
>From Dirt to Dollars: Uncovering the Silver Mining Process
Refining Silver Ore into Bullion: Smelting, Electrolysis, and Cupellation. Smelting: To eliminate impurities, the ore containing silver is crushed and fired in a furnace. When the ore is smelted, the silver that remains becomes concentrated into dore bars, an alloy comprising significant amounts of silver in addition to gold and other metals.
>23.2: Pyrometallurgy
The oldest, and still the most common smelting process for oxide ores involves heating them in the presence of carbon. Originally, charcoal was used, but industrial-scale smelting uses coke, a crude form of carbon prepared by pyrolysis (heating) of coal. The basic reactions are: [ce{MO + C rightleftharpoons M + CO }label{2.1}]

Oxygen-rich smelting processes are effective for low-grade bismuth ores [68], roughly divided into oxidation smelting and reduction smelting steps. The basic principle involves operators typically charging bismuth ore from the top of a furnace, ore particles rapidly heat up and melt in the reactor, forming bismuth oxide, slag, and gas phases.
>Guide to Modern Smelting Processes
furnaces or specialized smelting equipment, to initiate the smelting process. Chemical Reactions: The application of heat triggers chemical reactions that cause the reduction of metal oxides or other compounds, leading to the release and collection of the purified metal. Separation of Impurities: Impurities such as slag, gangue minerals, and non-
>Help with smelting and fluxing.
Smelting is in fact "chemistry" (meaning its "reactive") so a reaction (foaming) is/should be expected in "most" smelting - the exception being when using flux to remove "trace" contaminants when melting actual metals
>Gold Metallurgy
The method of leaching gold and silver from ore by air oxidation in an alkali cyanide aqueous solution is the most commonly used technology in modern times. Its principle is to oxidize the gold in the ore with oxygen in an alkali cyanide solution to form a cyanide gold complex. The chemical reaction is as follows:

>Coal-fuelled crucible lead-silver smelting in 12th-13th …
Silver-bearing lead bullion was produced at the site of Yanchuan by smelting argentiferous galena with metallic iron and no need for charcoal or carbon monoxide in the reaction vessel. Based on the analysis of a large iron bead in the slag, it is argued that the original iron charge was steel or even cast iron rather than low carbon wrought iron.
