Step-by-step solution

Siderite−FeCO3- {FeCO}_{3}

Siderite is a mineral composed of iron (II) carbonate (FeCO3). It is a widespread mineral that is an ore of iron.

Calamine−ZnCO3- {ZnCO}_{3}

Zinc ore is most commonly found as zinc carbonate (ZnCO3​), known as calamine or smithsonite.

Kaolinite−Al2(OH)4⋅Si2O5- {Al}_{2} ( OH{)}_{4} \cdot {Si}_{2}{O}_{5}

Malachite−Cu(OH)2⋅CuCO3- Cu ( OH{)}_{2} \cdot {CuCO}_{3}
