Several companies reclaim residual limestone 'fines' from slime dams. Quicklime Limestone is converted to quicklime through calcining in rotary or vertical kilns. In the lime process, for every ton of saleable quicklime produced, about 2 tons of 'pure' limestone or up to 6 tons of impure limestone is consumed.

Cone crushing is a process used in aggregate and mining operations to reduce large pieces of rock, ore, or minerals to smaller sizes. Cone crushing works by squeezing the material between an eccentrically gyrating spindle that is enclosed by a hard outer shell, known as the concave. The material is crushed by being compressed between the mantle ...

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).
