Options

  1. A( a ) - ( iii ) ,   ( b ) - ( ii ) ,   ( c ) - ( i ) ,   ( d ) - ( iv )
  2. B( a ) - ( iii ) ,   ( b ) - ( iv ) ,   ( c ) - ( i ) ,   ( d ) - ( ii )
  3. C( a ) - ( iv ) ,   ( b )   - ( i ) ,   ( c ) - ( iii ) ,   ( d ) - ( ii )
  4. D( a ) - ( iv ) ,   ( b ) - ( iii ) ,   ( c ) - ( ii ) ,   ( d ) - ( i )

Correct answer

A. ( a ) - ( iii ) ,   ( b ) - ( ii ) ,   ( c ) - ( i ) ,   ( d ) - ( iv )

Step-by-step solution

(a) Concentration of Ag is performed by leaching with dilute NaCN solution (b) Pig iron is formed in blast furnace (c) Blister Cu is produced in Bessemer converter (d) Froth floatation method is used for sulphide ores. Note : During extraction of Cu reverberatory furnace is involved.
