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

Smelting chrome ore ScienceDirect

Jan 01, 1976· The objective of chrome ore smelting is to convert the chromium into a form t h a t 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. The arc furnace is better suited to deal with the refractory nature of the gangue associated with the ore

Smelting Wikipedia

Smelting is a process of applying heat to ore in order to extract a base metal.It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

How to Smelt Iron: The 6 Steps to Iron Smelting The

1. Gather iron ore. Iron ore can be bought or gathered, but for the sake of demonstration, we gathered the ore ourselves. The best time to collect iron ore is in the winter because the ocean is more active. Active waves separate the black, magnetic sand from lighter silica sand.

Ferrochrome Wikipedia

Ferrochrome, or ferrochromium (FeCr) is a type of ferroalloy, that is, an alloy of chromium and iron, generally containing 50 to 70% chromium by weight.. Ferrochrome is produced by electric arc carbothermic reduction of chromite.Most of the global output is produced in South Africa, Kazakhstan and India, which have large domestic chromite resources.. Increasing amounts are coming from Russia and

From the Soil to the Iron Product the Technology of

Before smelting we roast the iron ore in a roasting pit. The bottom of the pit is covered in clay so that no soil gets into the furnace with the iron ore. In the pit we make a big fire and put the pieces of iron ore into it, then let the fire burn for about ten hours. During this process the water content of the iron ore is released, and its

Iron Ore HowStuffWorks

To get to the bits of iron in the ore, you have to smelt it out. Smelting involves heating up ore until the metal becomes spongy and the chemical 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.

Energy Use in US Steel Manufacturing Stanford University

This smelting process melts out and separates iron from the original rock material. Iron ore is mixed with coke, a form of very pure coal. The blast furnace burns the coke to heat the iron ore causing it to react into iron (Fe 2), nitrogen (N 2), and carbon dioxide (CO 2). This iron is often known as "pig iron" or "hot metal" as it is a liquid
