    2021-10-15 · Pyrite cinder (PyC) is an iron-enriched solid waste material, which is an important iron resource for steel industry. However, the separation or extraction of iron minerals and heavy metals from PyC was ineffective, because of the fine disseminated granularity and the intergrowth between iron minerals and toxic heavy metals during high temperature roasting.

    Copper (I) sulphide ( C u 2 S). 55%. Solution: In the extraction of copper from its sulphide ore, when ore is subjected to roasting, some of it is oxidised to C u 2 O which reacts with the remaining C u 2 S (sulphide ore) to give copper metal. C u 2 S + 2 C u 2 O → 6 C u + S O 2 ↑. Here C u 2 S behaves as reducing agent.
