What gas is released in the process of smelting?

Question

Quizplus · Accepted Answer

Smelting involves heating ores to extract metal from them. During this process, sulfur dioxide gas is released as a byproduct. This gas can be harmful to the environment and must be properly contained and treated. While other gases like carbon monoxide and carbon dioxide may be produced during smelting, sulfur dioxide is typically the most dominant gas released. Choice A and E are not the best options because while these gases may be produced during other industrial processes, they are not specifically associated with smelting. Choice B and D are not correct because chlorine and ammonia are not typically produced during smelting.
