What are the considerations for smelting iron and aluminum

One of the issues of smelting Fe and Al in Space is what minerals of each metal will be smelted. Different mineralogies dictate different smelting methods. Most open cut mines in Brazil and Australia produce an iron ore blended product of about 60 percent iron. Sweden mines iron ore from underground which contains 35 percent iron. Get price

Mining and Refining

Aluminium is an "energy bank"; most of the original input can be recovered every time the product is recycled. Bauxite mining requires relatively low energy inputs, compared to other steps in the aluminium production process – with less than 1.5 kilograms of fuel oil (mainly in the form of diesel for haul trucks) and less than 5 kWh of Get price

How Aluminum is Produced

The smelting process required to produce aluminum from the alumina is continuous the potline is usually kept in production 24 hours a day year-round. A smelter cannot easily be stopped and restarted. If production is interrupted by a power supply failure of more than four hours, the metal in the pots will solidify, often requiring an expensive Get price

Copper Purification Process

Copper Anodes: In copper processing, a copper anode is an intermediate product from the smelting furnaces which is used as a copper source from which to make copper cathodes during electrolysis. In electrolysis, it is the positive terminal. Oxidation occurs at the anode. The anode is replaced when it's been eroded too far and risk falling apart. Get price

Smelting Furnace

The smelting furnace generates process gas streams with SO 2 concentrations ranging from 0.5% to 80%, depending on the process used. It is important, therefore, that a process be selected that uses oxygen-enriched air (or pure oxygen) to raise the SO 2 content of the process gas stream and reduce the total volume of the stream, thus permitting Get price

Extraction and Refining of the Platinum Metals

A major development in the world's platinum industry took place in the early nineteen twenties when large deposits of platinum bearing ore were discovered in the Transvaal in South Africa.
