Question:
Copper matte comprises mainly of
Copper matte comprises mainly of
Show Hint
Matte = Double Sulphides ($Cu + Fe$). The goal is to later blow out the Iron sulphide to get pure copper.
Updated On: Jul 4, 2026
- Copper sulphide and Iron oxide
- Copper sulphide and Iron sulphide
- Copper sulphide and Iron sulphate
- Copper sulphide and copper oxide
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept In copper smelting, "matte" is the intermediate product formed in the furnace.
Step 2: Meaning Matte is a molten solution of sulphides that separates from the silicate slag.
Step 3: Analysis The purpose of matte smelting is to collect copper into a concentrated sulphide phase while rejecting iron as an oxide in the slag.
Step 4: Conclusion Consequently, copper matte consists of a mixture of $Cu_{2}S$ and $FeS$. Final Answer: (B)
