Aluminum Smelting | HowStuffWorks
Transforming alumina aluminum oxide into aluminum represented a major milestone in the industrial revolution. Until modern smelting techniques evolved, only small quantities of aluminum could be obtained. Most early processes relied on displacing aluminum with more reactive metals, but the metal remained expensive and relatively elusive.
Iron Ore Smelting Process Brighthub Engineering
The coke is used as a fuel to produce the high temperatures required by the process of smelting the ore in a blast furnace. It produces CO which adds heat, as well as acting as a reducer removing the oxygen content from the ore.
smelting | Definition Facts |
In modern copper smelting, a reverberatory furnace is used. Concentrated ore and a flux, commonly limestone, are charged into the top, and molten matte—a compound of copper, iron, and sulfur—and slag are drawn out at the bottom. A second heat treatment, in another (converter) furnace, is necessary to remove the iron from the matte.

What will happen if coal is used instead of coke in ...
Mar 22, 2016· Coke is a fuel with very low impurities and high carbon content. Usually coke is obtained by destructive distillation of bituminouscoal. So, if coal is used in smelting instead of coke the higher impurities content of coal will real with the molten iron formed and would result in undesirable products. Views · View Upvoters.
Gold Smelting Refining Process
Electric Gold smelting Furnace. The flux is a mixture of several reagent chemical such as borax, silica, sodium nitrate, sodium carbonate and fluorspar. Borax is a white crystalline mineral used in glass and ceramic enamel mixes. In the smelting process, borax helps to reduce the gold smelting point of the charge and capture metallic oxides. The addition of this reagent must be controlled; otherwise the .

Smelting and Refining Operations
The smelting of sulphidic ores produces a partially oxidized metal concentrate (matte). In smelting, the worthless material, usually iron, forms a slag with fluxing material and is converted into the oxide. The valuable metals acquire the metallic form at the converting stage, which takes place in .
