Uses of Limestone ScienceStruck

Limestone rock is a sedimentary rock which forms in the process of sedimentation at the bottom of lakes and oceans, or in caves. It is mainly composed of mineral calcite and aragonite, both of which are crystal forms of calcium carbonate. A limestone with 95 percent or more of calcium carbonate by weight is known as a high-calcium limestone.

Acid Mine Drainage (AMD) causes, treatment and case

The simplest method of neutralization involves the lining of a streambed with limestone, whereby water is treated as it flows over the limestone. However, this strategy is not necessarily effective because the limestone rapidly becomes coated with iron, calcium sulfate and biological growth, which inhibits interaction with mine water.
