Limestone for pH Adjustment in Industrial Wastewater Neutralzation
Limestone certainly does not hurt the process and it can be argued that it does help. However, if the limestone contact tank is going to displace an active chemical treatment stage or system then we must strongly discourage the use of this method. We will never use, under any circumstances, limestone exclusively.

Limestone Wastes For Production Of Concrete
Crushed limestone dust is a waste material from the production of concrete aggregate by crushing quarried limestone rocks. The dust is usually less tan 1% of the aggregate production. Although it is coarser than common cementing materials such as as Portland cement, coal fly ash and ground blast furnace slag, it is fine enough to cause many problems during materials handling and disposal.

Limestone
Limestone is the raw material for production of lime, primarily known for treating soils, purifying water and smelting copper. Lime is an important ingredient used in chemical industries. [109] Limestone and (to a lesser extent) marble are reactive to acid solutions, making acid rain a significant problem to the preservation of artifacts made from this stone.
