Nickel processing - Extraction, Refining, Alloying: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating …
It can be extracted from iron ore using a blast furnace. In a blast furnace, carbon monoxide is used to reduce iron(III) oxide to iron. Limestone is also added to remove impurities through chemical reactions that produce slag. The high temperatures needed for the extraction reactions are provided by coke or carbon in the blast furnace. …
Iron ore beneficiation is the process of improving the quality of iron ore by removing impurities and increasing its iron content. It is necessary to reduce alumina and silica in the feed. The process improves the chemical, physical, and metallurgical characteristics of the ore to make it a more desirable feed for iron-making furnaces.
