quality of limestone process
Limestone Wikipedia
Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.
How Cement Is Made
The heated air from the coolers is returned to the kilns, a process that saves fuel and increases burning efficiency. After the clinker is cooled, cement plants grind it and mix it with small amounts of gypsum and limestone. Cement is so fine that 1 pound of cement contains 150 billion grains.

What is the process of limestone formation? Quora
Over time these items would build up layers. As the layers became more substantial, they began to emit great pressure and heat upon the layers beneath them. As this pressure and heat began to reach extreme levels, the lowest layers would fuse together as great masses. This process is called lithification and the end result is limestone.
