to study the e traction of fe from its ore


The process of metal extraction from ore is dependent on the reactivity of the metal. Highly reactive metals are extracted by electrolysis. In order of decreasing reactivity, these metals are potassium, sodium, calcium, magnesium and aluminum. These metals are higher in the reactivity series than carbon.

Extraction of Nickel - QS Study. Main ore is Pentlandite; Nickel is extracted from ores through the Mond procedure, in which nickel oxides are purified throughout several steps into pure nickel metal. It is placed with hydrogen and carbon monoxide gases at 122 degrees Fahrenheit, which converts it to impure nickel.

At 900 - 1500 K, In the lower sections of the furnace, C + C O 2 → 2 C O. F e O + C O → F e + C O 2. The limestone also decomposes to CaO which removes the silicate impurity of the ore in the form of Slag. It can be easily separated out of molten iron. The iron manufactured in Blast Furnaces contain about 3 - 4 % of Carbon and smaller ...
