Identify the correct statement among the given choices?
Show answer Hide answer
Answer: C. Lead can be produced in a blast furnace
Explanation
Lead can be extracted from galena ores using traditional pyrometallurgical reduction in a furnace. Blast furnaces facilitate the high temperature chemical reduction of metal oxides and sulfides. Carbon monoxide acts as the primary reducing agent inside the high temperature smelting zone. Extractive metallurgy employs thermal and chemical methods to obtain pure metals from ores. Galena is the principal natural mineral ore source for producing commercial lead metal. Pyrometallurgy utilizes heat to drive chemical reactions that separate valuable metals from gangue.
Industrial metal production facilities use large blast furnaces for high volume smelting operations. Recycling plants also utilize furnace technologies to recover lead from spent automotive batteries. Metallurgical engineering practices emphasize environmental controls to capture hazardous smelting exhaust gases. Sphalerite is a zinc sulfide mineral rather than an oxide chemical compound structure. The first law thermodynamic energy balance expression contains incorrect sign conventions for work terms. Ferrooxidans is a bacterium rather than a fungus used in bioleaching mineral processes.
