Lime calcining is the conversion of limestone (CaCO3) to lime (CaO). Limestone is a sedimentary rock, the third most abundant mineral. Limestone is mostly quarried above ground; however, some underground limestone mining is done. Limestone is found with many different characteristics and different impurities.

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).
