Vedclass · Answer

(D) Calamine is $ZnCO_3$ and Cerrusite is $PbCO_3$,both are carbonate ores.Rutile is $TiO_2$ and Cuprite is $Cu_2O$,both are oxide ores.Zinc blende is $ZnS$ and Pyrites (like Iron pyrites $FeS_2$ or Copper pyrites $CuFeS_2$) are sulphide ores.Malachite $(CuCO_3 \cdot Cu(OH)_2)$ and Azurite $(2CuCO_3 \cdot Cu(OH)_2)$ are carbonate ores of $Cu$,not sulphate ores.Therefore,the statement in option $D$ is incorrect.
