How to Choose Correct Calcium Carbonate

Different grades of industrial calcium carbonate may vary in terms of particle size distribution, brightness, chemical purity, and other properties, depending on the intended use.

It's important to source it from reputable suppliers who adhere to food safety regulations and provide products that are labeled as "food grade" to ensure they are suitable for use in food processing and production.

Additionally, it's crucial to follow recommended usage levels and guidelines provided by food safety authorities to ensure the safe and appropriate use of products.

1. Calcium Carbonate Dense

"Dense" calcium carbonate typically means it's packed tightly with high bulk density. Bulk density measures how closely a substance is packed in a volume. Industries often choose dense calcium carbonate for more material in less space, which helps in manufacturing.

Depending on the purpose of using calcium carbonate in each industry, the manufacturer should choose the appropriate grade to save manufacturing costs:

• Industrial grade - Dense industrial-grade calcium carbonate typically has a high purity level and controlled particle size to meet the specific needs of industries where it is employed.

1. 1. Paper Industry: used as a filler material in the production of paper, where it improves the paper's whiteness, opacity, and smoothness.
   2. Paints and Coatings: used as a filler and extender in the production of paints and coatings to enhance the coverage, durability, and rheological properties of these products.
   3. Plastics Industry: used as a filler to reduce production costs, increase stiffness, and improve various properties of plastic products.
   4. Construction Industry: used to improve workability and provide certain desired properties of cement, concrete, and mortar.
   5. Adhesives and Sealants: used as a filler in adhesives and sealants to enhance their performance.
   6. Pharmaceuticals: used as a dietary supplement in pharmaceuticals and also as an antacid to relieve heartburn, acid indigestion, and upset stomach.
   7. Food Industry: used as a food additive (E170) and a white food coloring agent in products like toothpaste and baking powder.
   8. Environmental Remediation: used in wastewater treatment processes to control pH levels and remove impurities.
   9. Agriculture: used as a soil conditioner to neutralize acidic soils and provide essential calcium to plants.

• Food grade - refers to a specific quality and grade of calcium carbonate that is safe for consumption and approved for use in food products

1. 1. The European food additive number E170, generally recognized as safe (GRAS) by regulatory authorities in many countries, including the United States.
   2. Food Additive: used as a food additive in various food and beverage products, may be added for several purposes, including as a calcium supplement, a colorant, an anticaking agent, and as a pH regulator to adjust the acidity of certain foods.
   3. Calcium Supplement: a source of dietary calcium, which is an essential mineral for the human body and often added to foods like fortified cereals, orange juice, and dietary supplements to increase calcium intake.
   4. Colorant: used as a white food coloring agent to achieve a desired color or appearance in food products, such as white sauces, frosting, and certain candies.
   5. Anticaking Agent: used as an anticaking agent to prevent powdered or granulated food products, such as salt, sugar, and baking powder, from clumping and forming lumps due to moisture absorption.
   6. pH Regulator: used as a pH regulator to adjust and stabilize the acidity or alkalinity of certain foods and beverages.

2. Calcium Carbonate Light

Calcium Carbonate Light refers to a type of calcium carbonate that has a lighter density compared to other forms. It is commonly used in various industries for its specific properties and applications.
