Question

Cupellation Process Is Used in the Metallurgy Of?

• A. Copper
• B. Iron
• C. Aluminum
• D. Silver

Answer 1

The correct option is D

Silver

Explanation for the correct option:

Option(D): Silver

• The main principle of the cupellation process is that the metals which do not react or oxidize chemically can be separated from the ore by the basic metals which on heating form slag or other compounds and leave behind the metal unreacted.
• Cupellation is known as a process where ores are treated under high temperatures and controlled operations to separate noble metals i.e Gold and Silver, from base metals like lead, Copper, Zinc, and others present in the ore.
• Hence the given process was used generally used to extract Silver from smelted lead ores.

Explanation for the incorrect option:

Option(A): Copper

• The cupellation process is not used in the metallurgy of Copper.
• Thus, the given option does not coincide with the correct concept.

Option(B): Iron

• In the metallurgy of Iron, we do not use the cupellation process.
• Thus, the given option does not represent the correct concept.

Option(C):

• The cupellation process is not used in the metallurgy Of Aluminum,
• Hence, the given option is an incorrect one.

Hence, the Cupellation process is used in the metallurgy Of Silver.
