The dry grinding of size intervals of limestone samples showed that these samples followed the first-order breakage law with constant normalised primary breakage distribution function. The values of the primary daughter fragment distributions and the values of α in S i =a T X α are different in the samples of limestone.

Carbonates. Minerals in the carbonate group all have the elements carbon (C) and oxygen (O) arranged into what is called the carbonate anion, which is a carbon bonded with three oxygens: CO3–. Carbonate minerals play a key role in storing the world's carbon dioxide, a greenhouse gas, in solid form. They also make up the "hard parts" of some animals such …
