Uses of limestone Know About the Different Uses of

Limestone is a type of a sedimentary rock that is found naturally in the earth’s environment. The rock comprises primarily of chemical compound calcium carbonate (CaCO 3) in the form of calcite which is yet again a type of a mineral.It also contains other materials like quartz, clay minerals, pyrite, feldspar, and siderite amongst others.

2020-2-12  Feldspar is the most important single group of rock forming silicate minerals. There are four chemically district groups of feldspar; potassium feldspar (KAlSi 3 O 3), sodium feldspar (NaAlSi 3 O 8), calcium feldspar (CaAlSi 3 O 8) and barium feldspar (BaAl2Si 3 O 8). About 90% of produced feldspar is used for glass and
