What are the steps involved in extraction of moderately reactive metals

Moderate reactive metals are extracted from their ores by two steps: Step 1: Moderately reactive metals like Zn, Fe and Pb are converted into their oxides by calcination or roasting. Step 2: These metal oxides are thenreduced to metal using a suitable reducing agent like carbon, carbon monoxide or hydrogen. [2 Marks]

Assertion (A): The extraction of metals from their sulphide ores …

Roasting converts sulphide ores directly into metals is incorrect as roasting does not convert sulphide ores directly into metals. Instead, it converts sulphide ores into their oxides, which can then be reduced to metals in subsequent steps. This is crucial as metal oxides are generally easier to reduce to metals compared to their sulphides .
