Limestone next is subjected to particle size reduction, with the end size ranging from a couple inches to a few microns. The resulting material is heated and cooled to create lime. After the heating (or “calcinating”) process, the lime can be milled again and then hydrated or “slaked.”. Union Process has developed and patented an

Lime is produced in a two or three step process: stone preparation, calcination, and hydration. Calcination is the process by which limestone, which is mostly calcium carbonate (CaCO 3) is heated in a kiln to produce quick lime (CaO). Carbon dioxide is a byproduct of this reaction and is usually emitted to the atmosphere. However, some
