Why is metal refining important?
-
A.
To make metals heavier
-
B.
To remove unwanted impurities and obtain pure metal
-
C.
To convert metal oxides into metals
-
D.
To increase impurities in metals
Correct Answer:
B. To remove unwanted impurities and obtain pure metal
Explanation:
Metal refining is the essential process of purifying crude metal extracted from ores to eliminate contaminants and non-metallic substances. This procedure ensures the final product achieves the high level of purity required for industrial applications and improves the metal's physical and chemical properties. While extraction techniques like smelting convert metal oxides into raw metals, refining is the final stage needed to isolate the pure element from any remaining dross or unwanted alloys.
