Limestone has numerous applications in the treatment of industrial wastewater, especially in which acidic wastes need to be neutralized. Sulfuric acid based waste pickling solutions are neutralized with lime in steel plants. Lime is also used to precipitate chromium, copper and heavy metals in the treatment of wastes of coating plants.

the primary copper production is ,treated, by ,hydrated lime, (Ca(OH) 2). Due to low price of the ,lime, and its high efficiency, it is widely used for neutralization of acidic effluents. The main disadvantage of this process is generation of huge amounts of sludge, which is considered to be a hazardous waste since it contains toxic elements [11-13].
