Question: In the context of metallurgy, what is the primary purpose of roasting a sulfide ore?

Options:

To reduce the ore
To oxidize the ore
To concentrate the ore
To purify the ore

Correct Answer: To oxidize the ore

Solution:

Roasting a sulfide ore involves heating it in the presence of oxygen to convert it into an oxide, which is a necessary step for further extraction of the metal.

In the context of metallurgy, what is the primary purpose of roasting a sulfide ore?

Step 1: Start with a sulfide ore, which is a type of mineral that contains metal combined with sulfur.
Step 2: Heat the sulfide ore in the presence of oxygen (usually in a furnace).
Step 3: During heating, a chemical reaction occurs where the sulfur in the ore combines with oxygen to form sulfur dioxide gas.
Step 4: As a result of this reaction, the metal in the sulfide ore is converted into a metal oxide.
Step 5: The metal oxide can then be further processed to extract the pure metal.

Roasting of Sulfide Ores – The process of heating sulfide ores in the presence of oxygen to convert them into oxides, facilitating metal extraction.
