Explanation:
To find the number of metals extracted by pyrometallurgy, we need to understand what pyrometallurgy is and which elements can be extracted using this process.
Pyrometallurgy:
Pyrometallurgy is a branch of extractive metallurgy that involves high-temperature processes to extract metals from their ores. It relies on heat and a chemical reducing agent to decompose the ore and separate the metal from its impurities.
Elements extracted by pyrometallurgy:
Metals that can be extracted using pyrometallurgical processes include those that have high melting points and can be reduced by carbon or carbon monoxide. These metals are typically found in their ores as oxides, sulfides, or carbonates. Some common metals extracted by pyrometallurgy include iron, copper, lead, zinc, tin, and nickel.
Given elements:
Ca, Pb, Sn, Ag, Mg, Au, Zn, Cu, Al, Na, Hg
Analysis:
To determine the number of metals extracted by pyrometallurgy, we need to identify which of the given elements meet the criteria of having a high melting point and being reducible by carbon or carbon monoxide.
Metals extracted by pyrometallurgy:
1. Pb (Lead): Lead has a melting point of 327.5°C and can be reduced by carbon.
2. Sn (Tin): Tin has a melting point of 231.9°C and can be reduced by carbon.
3. Zn (Zinc): Zinc has a melting point of 419.5°C and can be reduced by carbon.
4. Cu (Copper): Copper has a melting point of 1084.6°C and can be reduced by carbon.
Therefore, the number of metals extracted by pyrometallurgy from the given elements is 4.
Conclusion:
Pyrometallurgy is a process that involves extracting metals from their ores using high temperatures and a chemical reducing agent. In the given list of elements, lead, tin, zinc, and copper meet the criteria for extraction by pyrometallurgy. Hence, the correct answer is '4'.
