Acid mine drainage (AMD) forms when sulfide minerals deep in the earth are exposed during mining, highway construction, and other largescale excavations. Upon exposure to water and oxygen, most sulfide minerals oxidize to form sulfuric acid, metal ions and sulfate, which, if untreated, enter surface or groundwater (Akcil and Koldas, 2006).

Limestone. Limestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earth's sedimentary crust. It is a basic building block of the construction industry (dimension stone) and a chief material from which aggregate, cement, lime and building stone are made. 71% of all crushed stone produced in the is either limestone or dolomite.

How Lime is Made

How Lime is Made

The limestone is heated as it moves down the kiln toward the lower end. As the preheated limestone moves through the kiln, it is "calcined" into lime. The lime is discharged from the kiln into a cooler where it is used to preheat the combustion air. Lime can either be sold as is or crushed to make hydrated lime.
