What is Pumice? How is it formed? What are its uses? In this article, we want to answer all your questions about Pumice Pumice. Stay with us. Pumice is the mineral pumice that is formed from molten material (magma) and volcanic eruption lava that formed on Earth during processes such as lowering temperature, pressure, and so on. This substance is called pumice in English. The reserves that extract pumice in Iran are Damavand, Sahand and Taftan.
In answer to the question of what is pumice, we can say that pumice is a volcanic substance that comes out of the crater in the form of fire lava.
When lava flows out of a volcano, they reach the earth’s surface and their temperature gradually decreases.
As the temperature decreases, a gas escapes from the lava, causing the pumice to become hollow.
Pumice is a porous rock that comes in a variety of sizes.
Pumice lightweight has many different colors.
For example, this lightweight grain in different colors such as:
Available in White, Milky, Cream, Brown, Orange, Gray, Black, etc.
What is the main structure of pumice?
The real structure of pumice is silicate. The appearance of this material is similar to glass and also has a porous property. More interestingly, the porosity of this product was very good and excellent. The amount of pumice is approximately 500 kg per cubic meter, which made pumice used in sound and heat insulation.
Pumice General Profile
Pumice is an aluminum silicate with igneous origin and cellular and porous structure.
This lightweight sponge is formed in explosive volcanic eruptions.
Pumice or mineral pumice has a network of gas bubbles in volcanic glass and minerals.
Pumice can be formed in different types of magmas such as basaltic, andesitic, dacitic and rhyolite magmas.
Pumice has the same origin and chemical composition and differs from pumice only in grain size.
Due to the fact that there is a lot of gas and water vapor in the composition of pumice and pumice, so the specific weight of these materials is usually very low and their volume is high. (The specific gravity of pumice is often less than one).
In nature, this stone is seen in white, gray, pink, pale yellow or brown. Grains larger than 2 mm are called pumice, and grains smaller than 2 mm are called pumice.

Various applications of pumice stone
To answer the main question in the article called what is pumice and the use of pumice stone, we go to one of the most common uses of pumice.
Due to its various properties, this pumice has been used in various industries. Most of these properties are mentioned in the construction and horticulture section.
It is also not moisturizing compared to vermiculite. While being able to keep water and food at a constant level.
This property makes it used in cold insulation. The nature of this expanded rock and its precise processing has created enough empty spaces in it, which leads to its use in filtration processes.
Insulation at low temperatures
The most important application of pumice at very low temperatures is its use in insulation and maintenance of tanks. Transportable tanks such as tankers are for storing liquid oxygen, nitrogen, argon, natural gas and other industrial gases that are stored in liquid form.
The temperature of these liquefied gases varies from -33 ° C for ammonia to -269 ° C for helium.
Therefore, the range of application of pumice in insulation will be at temperatures below zero degrees to -270 degrees Celsius.
In low temperature applications, pumice is also used in air distillation to produce oxygen, nitrogen and rare gases.
Pumice is also used to fill the layer between the outside wall and inside liquid storage tanks or production towers.
The advantage of pumice over other insulators is that it can be reused after changing the tank.
Plastic foams are more commonly used in European countries, but pumice still has many applications in low temperature insulation.
Pumice at high temperatures
Pumice insulation is used in steel and casting industries such as slag. In molten material that spills quickly from the pots or in molten molds.
Finally, pumice is used in casting sand as a CUSHION agent.
Mineral pumice is used in the manufacture of refractory parts and bricks. In the application of pozzolanic pumice, it can also be mentioned that expanded or raw granulated pumice is poured into pots and poured on molten metal surfaces.
Pumice particles are mixed with foam and pulp on molten material. Slag removal from molten material is easy.
Due to its refractory properties, which are resistant to 1100 ° C, pumice is used in the refractory industry in the preparation of refractory blocks and bricks.
After explaining about pumice and their use, it is better to make a few points about the preparation of pumice or mineral pumice.
Mines usually have the same production methods. In some mines, according to the needs of the market and customer demand and the type of pumice, strips and types of sieves are used.
Crushers, feeders and mineral transport machines are other items that should be considered in Pamis mines.
Application in agriculture
The use of pumice in agriculture is very wide. The industry is widely developing.
Limitation of water and soil resources as the two main inputs of agricultural production, plus problems such as salinity, sodium and soil wetland are important issues that we face in the country.
One of the most important ways out of crises is soilless cultivation (hydroponics). Today, the quantitative and qualitative limitations of water and soil resources are considered as the main basis of agricultural production on a global scale.
Given these conditions, it seems necessary to adopt new policies and provide better conditions to meet the nutritional needs of plants.
Is Pumice cheap?
In the meantime, the use of pumice is a completely economic and scientific proposal. Pumice is widely used in agriculture due to its high water absorption and water retention.
Mineral pumice is important as insulation in cold stores, greenhouses.
What is interesting about the consumption of this mineral pumice in the soil? Pumice prevents the growth of various and dangerous toxins, especially aflatoxins. It also reduces the destructive effects of toxins on stems and leaves.
The unique feature of mineral pumice leads to the production of healthier agricultural products.
Reducing the presence of these toxins in the leaves, stems and seeds of the plant in proportion to its consumption by livestock and ultimately adding it to animal feed results in healthier protein production.
What is pumice powder?
Pamis powder is one of the major products of Poke mines.
Filler is another name for this type of product.
As the English name implies, filler means filler.
As for the size of this powder, each mine has its own size. Because the granulating machines are adjusted according to their sales policy and the amount of market demand and… by the mine management.
Properties that, depending on the chemical and physical analysis of the pumice and mine, differentiate the types of mineral pumice powder size.
Powdered pumice produced in Pamis mine mixes well with cement due to its very low weight compared to ordinary sand (washed / river).
It is worth mentioning that with the use of Kanyar lightweight pozzolanic powder pumice, the optimal consumption of cement in concrete making workshops, blocking is reduced.
Its powder is also used as a filler for building plumbing surfaces, making various types of mosaics and street puzzles, and so on.
Preparation of pumice in mines
The product operation workshop typically includes the following:
Combines screens, rollers and hammer mills, rotary dryers, air-concentrating plates as needed, grain sizing systems using sieves, and grain mixing systems.
Screens are used to remove a variety of impurities such as organic matter and rock components larger than required.
Grinding materials larger than needed with more rollers and hammer mills.
If the material extracted from the mine is slightly damp, it is dried in a rotary dryer before or after crushing.
How to consume?
Various methods of screening and mixing are used to access the material that is suitable for the end use.
For example, the pumice used in abrasives is taken directly to air separators after sieving.
Granulation by size may also be done by sifting machines.
As the smaller particles pass through a special silk fabric due to the vibration of the device. Finally, granulated products typically need to be packaged for shipping or shipping.
