Question

an ore on heating in air gives sulphur dioxide gas. name the method in each metallurgical step that will be required to extract this metal from its ore???​

Answer 1

Answer:

.

Since the ore on heating in air gives Sulphur dioxide which means that the ore is a sulphide ore. The various methods involved in the extraction of metals from sulphide ores are as follows:

1. The ore is concentrated by the process of froth flotation to remove the impurities.

2. The concentrated ore is then heated in presence of air to convert the ore to corresponding metal oxide.

3. The metal oxide is then made to react with carbon to reduce the metal oxide to corresponding metal.

4. The metal is then purified by electrolytic reduction.
