Dirty Business - American Chemical Society
Calcium carbonate is chalk, or limestone, and is often found in dietary supplements as a source of calcium and as an ingredient in some antacids, such as “Tums”. An additional commercially touted benefit of this reaction is the removal of carbon dioxide (an extremely small amount) from the atmosphere, thus reducing the Green House Effect.

Covalent network solids contain elements from the carbon group because they have four valence electrons and can create three-dimensional shapes.
Difference Between Metallic and Non-metallic Minerals …
Minerals are defined as the homogeneous substances that occur naturally under varying conditions, in different types of geological environment. It is broadly classified into two egories, i.e. metallic minerals and non-metallic minerals. Metallic Minerals is composed of metals in their original form, whereas no metals are found in non-metallic minerals.
