Correct Answer
Detailed Explanation
A. Zone refining: Zone refining is a process used to purify semiconductors, such as germanium, hence it corresponds to IV.
B. Froth floatation process: This process is used for the concentration of sulphide ores, and it is used for the dressing of ZnS, hence it corresponds to I.
C. Cyanide process: This process is used for the extraction of gold (Au), hence it corresponds to II.
D. Electrolytic reduction: This process is used for the extraction of aluminum (Al), hence it corresponds to III.
Matching these with the options provided, we find that the correct answer is:
2 .A-IV, B-I, C-III, D-II.
