In the metallurgy of antimony, the pure metal is recovered by different reactions, depending on the composition

Question:

In the metallurgy of antimony, the pure metal is recovered by different reactions, depending on the composition of the ore. For example, iron is used to reduce antimony in sulfide ores:

Carbon is used as the reducing agent in oxide ores:
