Smelting - an overview | ScienceDirect Topics

Smelting furnaces produce liquid Cu–Fe–S matte (usually 60–70% Cu), which must have its sulfur and iron removed to make copper metal. This is most frequently done in submerged-tuyere Peirce–Smith (Fig. 4) and Hoboken converting furnaces using air (often slightly O 2-enriched) as the oxidant.The process is similar to submerged-tuyere smelting except that the feed is molten matte, not ...

The iron is then drained from the bottom of the furnace into a mould and allowed to harden. 16 The blast furnace remains the principal method of smelting iron to this day. 14. There is a tradeoff for this speed, however: melting the iron causes it to take on a very high (2-4%) carbon content, thus resulting in brittle cast iron.

Ilmenite smelting: the basics - SAIMM

In ilmenite smelting, the iron content of the oxide is also lowered by reduction to metallic iron, but this takes place in the liquid state, at a much higher temperature (of around 1650°C). Ilmenite smelting thus yields two products: a titania-rich slag, and molten iron. This is in contrast with the Becher process, where the iron is removed as ...

Iron Smelting in the Industrial Revolution

Iron Smelting is the process of making iron ore into iron. The smelters heat up the iron ore to melting point using charcoal as fuel. They then cast the heated iron ore into ingots called pigs. The ingots were either reheated and cast into moulds or they were heated and hammered into wrought iron which is more malleable. This job was usually ...

Smelting - Hyperleap

Ore is extracted from the earth through mining and refined, often via smelting, to extract the valuable element or elements. It is not known when or where the smelting of iron from ores began, but by the end of the 2nd millennium BC iron was being produced from iron ores from Sub-Saharan Africa to China. Slag is the glass-like by-product left over after a desired metal has been separated (i.e ...

Iron Ore | HowStuffWorks

In a bloomery, the fire doesn't get hot enough to melt the iron completely. Instead, the iron heats up into a spongy mass containing iron and silicates from the ore. Heating and hammering this mass (called the bloom) forces impurities out and mixes the glassy silicates into the iron metal to create wrought iron. Wrought iron is hardy and easy ...
