Not Correctly Matched Extraction Processes
Leaching, smelting, cyanide process, and electrolyte reduction are all extraction processes used in metallurgy. Each process is used to extract a specific metal from its ore. In this question, we need to identify the option that is not correctly matched.
Explanation:
Leaching: Extraction of Au, Ag
Leaching is a process used to extract metals from their ores using a solvent. In this process, the metal is dissolved in a solvent and then separated from the gangue. The solvent used in the leaching process depends on the metal being extracted. For example, gold and silver are extracted using a cyanide solution.
Smelting process Cu and Fe
Smelting is a process used to extract metals from their ores by heating the ore to a high temperature, causing the metal to melt and separate from the gangue. Copper and iron are extracted using the smelting process.
Cyanide process : Extraction of Sn and Pb
The cyanide process is used to extract gold and silver from their ores. It involves the use of a weak cyanide solution to dissolve the gold or silver from the ore. The metal is then precipitated from the solution using a reducing agent.
Electrolyte reduction : Extraction of Al
Electrolyte reduction is a process used to extract metals from their ores using electricity. Aluminum is extracted using the electrolyte reduction process.
Correct Option:
The option that is not correctly matched is option (c) Cyanide process: Extraction of Sn and Pb. The cyanide process is used to extract gold and silver, not tin and lead. Tin is usually extracted using the smelting process, while lead is extracted using the froth flotation process.
Therefore, the correct answer is option (c).
