How many of the following are classified as carbonate ores? Siderite, Malachite, Calamine, Azurite, — Metallurgy and Isolation of Elements Chemistry Question

💡 Solution & Explanation

The carbonate ores are: Siderite ($FeCO_3$), Malachite ($CuCO_3 \cdot Cu(OH)_2$), Calamine ($ZnCO_3$), Azurite ($2CuCO_3 \cdot Cu(OH)_2$), Dolomite ($CaCO_3 \cdot MgCO_3$), and Magnesite ($MgCO_3$). This makes a total of 6 carbonate ores.
