WHAT IS LIME
The word “lime” refers to products derived from burnt (calcined) limestone, such as quicklime and hydrated lime. Limestone is a naturally occurring and abundant sedimentary rock consisting of high levels of calcium and/or magnesium carbonate, and/or dolomite (calcium and magnesium carbonate), along with small amounts of other minerals. It is extracted from quarries and underground mines all over the world.
Lime and limestone products are among the oldest materials used in a diverse range of applications. Today these products serve as an essential building block in every industrial process.

Lime is commonly used to describe one of the following products:
- Calcium oxide/quicklime
- Calcium hydroxide/ hydrated lime
- Ground calcium carbonate/limestone
- Precipitated calcium carbonate/PCC
- Other calcium products
