The production of high calcium quicklime begins with the selective mining of chemically suitable calcium carbonate typically containing less than 5% magnesium carbonate. Throughout the manufacturing process, we carefully monitor the process to minimize impurities and produce a high calcium quicklime that is highly reactive and has the required particle surface area.
High calcium hydrated lime in powdered form typically has at least 75% calcium oxide and 25% water. High calcium hydrated lime easily forms as a suspension or slurry and is then often pumped to multiple process locations within industrial plants. The resulting solution is strongly alkaline, having a pH of around 12.4.
High calcium hydrated lime offers our customers several benefits such as:
