Both quicklime and hydrated lime can be converted into slurry through specialized equipment systems. Quicklime is reacted with water in a device called a "Slaker" through a process called "slaking".Slaking is an exothermic process meaning that heat is produced as the quicklime reacts with water and this heat must be managed by carefully controlling the ratios of water and lime, and any ...

Lime has strong water absorption, and reacts with water to become calcium hydroxide (Ca(OH)2), commonly known as slaked lime or slaked lime. It has little solubility in aqueous solution, but it can further ionize calcium ions (Ca2+) and hydroxide ions (OH) in aqueous solution, making the solution more alkaline. 2 Lime in gold flotation
