Question

why we convert slpheide ores to oxide ores​

Answer 1

Answer:

Explanation:

Compounds of certain metals reduce to metals without using any additional reducing agent ores of Cu, Pb, Hg etc. Their sulphide ores are partially roasted to give some oxide. This oxide is now reduced to the metal by the remaining sulphide ore at elevated temperatures in the absence of air.

Answer 2

Answer:

Carbonate and sulphide ores are usually converted into oxides during the process of extraction. ... Answer: Obtaining a metal from its oxide is much easier than doing that from a metal sulphide or carbonate. Due to this; metal sulphides and carbonates are first converted to metal oxides during metallurgy.
