Calcite is a common mineral exist in nature with chemical formular of CaCO3.It is usually white but also colorless, gray, red, green, blue, yellow, brown and orange. Calcite is most common as massive material in limestone and marble. So today's calcite powder grinding equipment plays an important role in mining industry. Th calcite after processing by powder grinding equipment have widely use. Now we will show the application of calcite.
Uses of Calcite in Construction
The construction industry is the primary consumer of calcite in the form of limestone and marble. These rocks have been used as dimension stones and in mortar for thousands of years. Limestone blocks were the primary construction material used in many of the pyramids of Egypt and Latin America. Today, rough and polished limestone and marble are still an important material used in prestige architecture.
Modern construction uses calcite in the form of limestone and marble to produce cement and concrete. These materials are easily mixed, transported and placed in the form of a slurry that will harden into a durable construction material. Concrete is used to make buildings, highways, bridges, walls and many other structures.
Uses in Acid Neutralization
Calcite has numerous uses as a neutralizer of acids. For hundreds of years, limestones and marbles have been crushed and spread on fields as an acid-neutralizing soil treatment. They are also heated to produce lime that has a much faster reaction rate in the soil.
Calcite is used as an acid neutralizer in the chemical industry. In areas were streams are plagued with acid mine drainage, crushed limestone is dispensed into the streams to neutralize their waters.
Calcium carbonate derived from high purity limestones or marbles is used in medicine. Mixed with sugar and flavoring, calcium carbonate is made into chewable tablets used in the neutralization of stomach acids. It is also an ingredient in numerous medications used to treat digestive and other ailments.
Calcium Carbonate Sorbents
Sorbents are substances that have the ability to "capture" another substance. Limestone is often treated and used as sorbent material during the burning of fossil fuels. Calcium carbonate reacts with sulfur dioxide and other gases in the combustion emissions, absorbs them and prevents them from escaping to the atmosphere.
Monuments and Statuary
Marble is an attractive and easily worked rock that has long been used for monuments and sculptures. Its lack of significant porosity allows it to stand up well to freeze-thaw action out-of-doors and its low hardness makes it an easy stone to work. It has been used in projects as large as the pyramids and as small as a figurine. It is widely used as cemetery markers, statues, mantles, benches, stairways and much more.
Many Other Uses
In a powdered form, calcite often has an extremely white color. Powdered calcite is often used as a white pigment or "whiting". Some of the earliest paints were made with calcite. It is a primary ingredient in whitewash and it is used as an inert coloring ingredient of paint.
Pulverized limestone and marble are often used as a dietary supplement in animal feed. Chickens that produce eggs and cattle that produce milk need to consume a calcium-rich diet. Small amounts of calcium carbonate are often added to their feeds to enhance their calcium intake.
As we can see, calcite application can not seperate with powder grinding equipment. Without the device, it can not widely use in custruction. Should you have any questions, please do no hesitate to contact me. Your inquiry will be highly regatd.
