Calciment is an economical acid neutralization agent due to its high alkalinity. When waste acids are neutralized and mechanically dewatered Calciment improves dewatering performance. Filter cakes typically contain higher solids (less water), separate easily from filter fabric, and solidify to improve handling. Simple laboratory tests can determine neutralization efficiency and solids generation for cost evaluation. Calciment is typically screw fed from a storage silo directly to a continuously agitated neutralization tank and pumped to the dewatering process.

Calciment is an ideal additive for neutralization and solidfication of coal processing refuse. Coal refuse contains pyrites that when exposed to air generates acid commonly known as acid mine drainage. Calciment not only neutralizes the acid generated but solidfies the unstable refuse called gob. Gob solidfication reduces the potential for acid generation by limiting the infiltration of water which becomes acidic.
