Step-by-step solution

Siderite - FeCO 3 Siderite is a mineral composed of iron (II) carbonate (FeCO 3 ). It is a widespread mineral that is an ore of iron. Calamine - ZnCO 3 Zinc ore is most commonly found as zinc carbonate (ZnCO 3 ​), known as calamine or smithsonite. Kaolinite - Al 2 ( OH ) 4 · Si 2 O 5 Malachite - Cu ( OH ) 2 · CuCO 3
