Metallic gold frequently is found in aluminosilicate rocks and it is finely dispersed among other minerals. It may be extracted by treating the crushed rock with aerate potassium cyanide solution. During this process metallic gold is slowly converted to [Au(CN)2]-, which is soluble in water. After equilibrium has been reached the aqueous phase is umped off and the metallic gold is recovered from it by reacting the gold complex with zinc, which is converted to [Zn(CN)4]2-. Gold in nature is frequently alloyed with silver which is also oxidized by aerated sodium cyanide solution. Silver occurs as native as well as sulphurised ore.
Q.
The process described above in the passage is regarding :
- a)Ore dressing
- b)Pyrometallurgical extraction
- c)Hydrometallurgical extraction
- d)Purification of metal
Correct answer is option 'C'. Can you explain this answer?

The process described in the passage is regarding Hydrometallurgical extraction
Hydrometallurgical extraction involves using aqueous solutions to extract metals from their ores. In this case, metallic gold is extracted from aluminosilicate rocks using aerated potassium cyanide solution. The process involves converting metallic gold to a soluble gold complex ([Au(CN)2]-) which can be recovered from the aqueous phase.
Steps involved in the hydrometallurgical extraction process:
- Treating crushed rock with aerated potassium cyanide solution
- Conversion of metallic gold to a soluble gold complex ([Au(CN)2]-)
- Recovery of gold complex from the aqueous phase by reacting it with zinc
- Formation of zinc cyanide complex ([Zn(CN)4]2-)
This process is an example of hydrometallurgical extraction as it involves the use of aqueous solutions to extract gold from its ore. It is an alternative to pyrometallurgical extraction which involves high-temperature processes such as smelting. Ore dressing, on the other hand, involves the physical separation of minerals from the ore. The process described in the passage is focused on the extraction of gold using chemical reactions in a liquid medium.
