Q: What is the main purpose of roasting in metallurgy?
Solution:
Roasting is used to convert metal sulfides into oxides, making them easier to reduce.
Steps: 7
Show Steps
Step 1: Understand that roasting is a process used in metallurgy, which is the study of metals.
Step 2: Know that many metals are found in nature as sulfides, which are compounds that contain sulfur.
Step 3: Realize that sulfides are not easy to work with when trying to extract the metal.
Step 4: Learn that roasting involves heating these metal sulfides in the presence of oxygen.
Step 5: Recognize that this heating converts the sulfides into metal oxides.
Step 6: Understand that metal oxides are easier to reduce, meaning they can be turned into pure metals more easily.
Step 7: Conclude that the main purpose of roasting is to prepare metal sulfides for easier extraction of the metal.
