Calcium hydroxide, also known as slaked lime or hydrated lime, is typically produced from limestone through a process called slaking. Here are the steps involved:
Quarrying: Limestone is extracted from quarries and transported to a processing plant.
Calcination: Limestone is heated to a high temperature (around 1000°C) in a lime kiln to produce calcium oxide (also known as quicklime). This process is called calcination and drives off carbon dioxide from the limestone, leaving behind calcium oxide.
Slaking: Quicklime is then mixed with water in a process called slaking. The water causes a chemical reaction that produces calcium hydroxide:
CaO + H2O → Ca(OH)2
