About High Calcium Limestone
High calcium limestone (calcium carbonate, CaCO3) is crucial in the agriculture market to ensure that poultry, cattle, pigs, and (other) livestock have an adequate amount of calcium in their diets. Appropriate levels of calcium ensure high-quality milk and egg production.
Limestone is a naturally occurring sedimentary rock that is composed almost entirely of calcium carbonate. Carmeuse limestone mines and quarries consistently provide high-quality limestone to the agriculture market. High calcium limestone from Carmeuse contains 95% or greater calcium carbonate and 2% or less magnesium carbonate and its level of solubility is suitable for animals. A wide variety of sizes is also available to meet the individual needs of each user.
Several needs should be taken into consideration when selecting the right product for your cattle, poultry and pig feed blends:
- Sizing requirements
- Purity requirements
- Calcium content
- Magnesium content
- Solubility requirements
- Access to the product
Why should you use High Calcium Limestone from Carmeuse for your animal feed needs?
- Calcium carbonate content of 95% by weight or greater
- Magnesium carbonate content of 2% by weight or less
- Sizing to meet your needs
- Improves ingestion rates promoting animal growth
- Solubility suitable for laying hens or milk producing cows avoiding wasted material
High Calcium Limestone Uses
High calcium limestone has many different uses across several industries including its use in animal feed. High calcium limestone is an extremely economical source of calcium for animals which can prevent poor growth rates, bone development, and reduced milk output.
High calcium limestone is also used in construction materials such as roofing shingles, glass, and asphalt.
High calcium lime has many uses in agriculture alone. High calcium limestone supplies essential nutrients as a feed supplement for animals such as chickens and cows. High calcium limestone, can also be used as ag lime to neutralize acidic soils, boost fertilizer, provide important nutrients and improve drainage and root development.
The main difference between high calcium and dolomitic lime has to do with the amount of magnesium present. Lime is a term that can describe a variety of materials, all calcium based. High calcium quicklime is derived from high calcium limestone by heating it, usually in (rotary) kilns, to approximately 1100 °C. Quicklime can be further processed into hydrated lime, a finely sized and high-purity product, by adding the proper amount of water and agitation. When dealing with agricultural applications, lime refers to finely sized limestone. The different materials are used for a wide range of different applications. Whether it’s for agricultural purposes, steel, construction, building supplies or something else. It’s important to know what type of lime is needed.
High calcium limestone has a calcium carbonate level of 95% or more and a magnesium carbonate level of less than 2% by weight. It is sometimes referred to as a number of similar terms, including, calcitic, low mag, high cal or hical. Although dolomitic limestone is still primarily calcium carbonate, it contains elevated levels of magnesium carbonate (MgCO3) and is not the same as high calcium lime.
