Inert Anode Technology - The Aluminum Smelting Process

Anode change operations are one of the most critical tasks to be performed in a smelter, requiring upstream an entire separated plant for manufacturing new anodes (usually called “Carbon Plant”) and recycling of the spent ones.

Aluminium smelting - Wikipedia

Aluminium smelting is the process of extracting aluminium from its oxide, alumina, generally by the Hall-Héroult process.Alumina is extracted from the ore bauxite by means of the Bayer process at an alumina refinery.. This is an electrolytic process, so an aluminium smelter uses huge amounts of electricity; smelters tend to be located close to large power stations, often hydro-electric ones ...

Reducing agent - Wikipedia

A reducing agent (also called a reductant or reducer) is an element or compound that loses (or "donates") an electron to an electron recipient (oxidizing agent) in a redox chemical reaction.. A reducing agent is thus oxidized when it loses electrons in the redox reaction. Reducing agents "reduce" (or, are "oxidized" by) oxidizing agents.

May 10, 2021· But aluminum does not have to be so polluting. Leading producers use renewable energy and ground-breaking technology innovations such as inert anode to reduce direct emissions in primary production. Imagine if aluminum production generated oxygen, rather than carbon, in the smelting process?
