What is lime stone? How it made?

Limestone is a sedimentary rock composed mostly of calcium carbonate (CaCO3). It is formed from the accumulation of shells, coral, algae, and other organic materials over time. As these materials settle to the bottom of the ocean or lake, they become compacted and eventually form limestone rock. Over time, the rock can be subjected to heat and pressure, causing it to recrystallize into a denser form known as marble.

Limestone is commonly used for building materials, such as tiles, countertops, and flooring, as well as for the production of cement, glass, and steel. To make these products, the limestone rock is quarried and then crushed into smaller pieces. Depending on the intended use, the crushed limestone may be further processed to remove impurities or to produce specific particle sizes. For example, to make cement, the limestone is ground into a fine powder and mixed with other materials to form a paste that can be molded into different shapes. To make tiles, the limestone is cut into thin slices and then polished to create a smooth, shiny surface.

Overall, the production of limestone-based products typically involves quarrying, crushing, processing, and shaping the material to meet specific specifications and requirements.
