|
Concentration of Ores |
Dressing or benefaction Removal of the unwanted materials or gangue |
|
Hydraulic Washing |
Based on differences in specific gravities of the ore and the gangue particles |
|
Froth Floatation Method |
Used for removing gangue from sulphide ores |
|
Pig Iron |
Obtained from Blast furnace It contains about 4% carbon and many impurities, e.g. S, P, Si, Mn in a smaller amount |
|
Cast Iron |
It is made by melting pig iron with scrap iron and coke using a hot air blast It contains about 3% carbon It is extremely hard and brittle |
|
Wrought Iron |
It is malleable and is the purest form of iron used commercially It is prepared from cast iron by oxidising impurities in a reverberatory furnace that is lined with haematite |
|
Mond Process |
It is used for refining Nickel It is a vapour phase refining First Ni is heated with carbon monoxide to produce nickel tetracarbonyl (volatile complex) and then it is decomposed at a higher temperature to obtain pure metal |
|
Van Arkel Method |
It is used for refining Zirconium or Titanium It is a vapour phase refining Useful in removing oxygen and nitrogen impurities |
