Smelting chrome ore - ScienceDirect
The objective of chrome ore smelting is to convert the chromium into a form that can readily be used by the steelmaker. Although chrome has been smelted in blast furnaces, it more commonly is reduced in submerged-arc electric furnaces.

Chrome Ores on Ferrochrome Smelting
Abstract—Chrome ores from six locations across the Bushveld Igneous Complex in South Africa are used to investigate the effects of ore types on the smelting processes, such as the consumption of fluxes, reductant; and most importantly, the consumption of electricity. The electric energy consumption is highly related to the SiO 2

Chromium processing | Britannica
The aluminothermic process begins with the roasting of fine ore, soda, and lime in air at 1,100 °C (2,000 °F). This creates a calcine containing sodium chromate, which is leached from the insoluble gangue and then reduced and precipitated as Cr 2 O 3.

Chromite - Wikipedia
During high temperature smelting of chromite ore to produce ferrochrome, Cr-III is converted to Cr-VI. As with chromite ore, ferrochrome is milled and therefore produces Cr-VI. Cr-VI is therefore introduced into the dust when the ferrochrome is produced.

How Iron and Steel Work - Iron Ore | HowStuffWorks
Smelting involves heating up ore until the metal becomes spongy and the stone compounds in the ore begin to break down. Most important, it releases oxygen from the iron ore, which makes up a high percentage of common iron ores. The most primitive facility used to smelt iron is a bloomery. There, a blacksmith burns charcoal with iron ore and ...

smelting | Definition & Facts | Britannica
Smelting, process by which a metal is obtained, either as the element or as a simple compound, from its ore by heating beyond the melting point, ordinarily in the presence of oxidizing agents, such as air, or reducing agents, such as coke.The first metal to be smelted in the ancient Middle East was probably copper (by 5000 bce), followed by tin, lead, and silver.
