E Traction Of Iron Smelting Roasting

From the Soil to the Iron Product

From the Soil to the Iron Product

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 structure becomes looser, which makes it easier to ...

Nickel: smelting, producingMetalpedia

Nickel: smelting; Extraction and purifiion; Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel appliions, 75% pure nickel can be used without further purifiion, depending on the composition of the impurities.
