Limestone is a sedimentary rock composed primarily of calcite, a calcium carbonate mineral with a chemical composition of CaCO 3. It usually forms in clear, calm, warm, shallow marine waters. Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris.

Limestone mining and utilization in Missouri began in the mid 1800s. The amount mined prior to 1920 is not known for certain. Since that time, however, reliable statistics do indicate that 3.1 billion short tons of limestone having a present value of about $17.5 billion have been mined in Missouri from 1920 to present.

Reclamation is the process to restore the ecological integrity of these disturbed mine land areas. It includes the management of all types of physical, chemical and biological disturbances of soils such as soil pH, fertility, microbial community and various soil nutrient cycles that makes the degraded land soil productive.
