Which of the following process is involved in the extraction of corresponding metal when Zinc Blende is used as ore?

Consider the following metallurgical processes : (I) Heating impure metal with CO and distilling the resulting volatile carbonyl (b.p. 43^(@)C) and finally decomposition at 150^(@)-200^(@)C to get the pure metal. (II) Heating the sulphide ore in air until a part is converted to oxide and then further heating in the absence of air to let the oxide react with unchanged metal sulphide. (III) Electrolysis of the molten electrolyte containing approximately equal amounts of the metal chloride and NaCl to obtain the metal. The processes used for obtaining magnesium , nickel and copper are respectively.

In an ideal crystal, the entropy of the constituents at absolute zero temperature (0K) is zero. However, the crystals generally suffer from certain defects also called imperfections They may be both electronic and atomic in nature. The atomic imperfections may be stoichiometric (Schottky and Frenkel defects) or non-stoichiometric (metal excees and metal deficiency defects). In addition to these, there are impurity defects which are caused by the addition of certain impurities of metals and this is known as dopping. The dopping leads to semi conductors which may be either n-type or p-type in nature. Zinc oxide (ZnO) is white when cold and yellow when hot. It is due to the development of :
