Question

All of the given ores are sulfide ores, except

• A. galena
• B. cinnabar
• C. zinc blende
• D. barytes

Answer 1

The correct option is D barytes

Galena $\left(PbS\right)$ is an ore of lead
Cinnabar $\left(HgS\right)$ is an ore of mercury
Zinc blende $\left(ZnS\right)$ is an ore of zinc
Barytes $\left(BaS{O}_4\right)$ is an ore of barium
Barytes is the sulfate ore while galena, cinnabar, and zinc blende are the sulfide ores
