Maifan Stone
What is Maifan Stone?
Maifan stone filter media is a natural porous mineral material, mainly composed of aluminosilicates. It is an igneous rock rich in minerals such as calcium, magnesium, potassium, zinc, iron, and silicon. It has strong adsorption and release properties for water-soluble minerals. It features a porous structure, stable composition, high mechanical strength, large specific surface area, and good adsorption performance.
As a water treatment filter medium, it can effectively adsorb heavy metal ions, suspended solids and some organic matter in water, while slowly releasing beneficial minerals such as calcium, iron, sodium and magnesium to improve the taste of water.
The products are widely used in drinking water purification, sewage treatment, constructed wetlands, aquaculture, and feed additives. In terms of appearance, maifan stone is usually grayish-white, grayish-green, or light brown, or has a certain luster and is relatively hard.
Types of Maifan Stone
Soft maifan stone and hard maifan stone generally refer to two different types of medical stone. Their main difference lies in the content of mineral components and physical hardness, which in turn affects their effectiveness in different applications.
Soft Maifan Stone
The soft maifan stone, as well known as golden soft maifan stone, generally refers to the type of maifan mineral stones that are rich in minerals, has a lower hardness and a softer texture. This type of medical stone usually contains more soluble minerals, such as calcium, magnesium, potassium, etc., which can easily release these elements in water and improve water quality more quickly.
Characteristic of soft maifan stone:
- Rich in mineral composition: Soft maifan stone contains a high proportion of minerals, especially trace elements such as calcium, magnesium, zinc, etc. that are beneficial to water quality
- Low hardness: Soft medical stone has a lower hardness and is therefore easier to break and dissolve.
- High solubility: The minerals in soft medical stone are highly soluble in water and can improve water quality more quickly, especially in softening and mineralizing water.
Golden soft maifan stone for drinking water is usually used for mineralization and softening due to its high mineral solubility. It can effectively adjust the hardness of water and provide minerals that are beneficial to the human body. The medical stone is commonly found in household water treatment equipment as an important component of water filters, helping to improve water quality and increase the mineral elements in water.
Golden soft maifan stone is named for its rich minerals and special golden appearance. The formation of this color may be related to the content of iron, manganese and other elements in its minerals, especially the presence of iron makes its color brighter.
Hard Maifan Stone
Hard maifan stone refers to a type of maifan mineral stones that contain more hard minerals (such as quartz, feldspar, etc.) in its mineral composition, with higher hardness and harder texture. The mineral release rate of this type of maifan stone is slower, the mineral composition is relatively stable, and it is usually not easy to dissolve.
Characteristic of hard maifan stone:
- Higher mineral hardness: The minerals in hard medical stone are higher in hardness and are not easy to break and dissolve.
- Stable mineral composition: Compared with soft medical stone, hard medical stone releases minerals more slowly and is usually used in application scenarios that require a longer maintenance effect.
- Lower solubility: The mineral components of hard medical stone dissolve more slowly in water, making it more suitable for long-term use, gradually releasing the minerals.
Due to its slower solubility, hard maifan stone is often used in water treatment systems that run for a long time, such as industrial water treatment, aquaculture water, etc. It can continuously improve water quality and reduce the need for frequent replacement of filter materials.
Hard maifan stone is commonly used in agriculture as a soil conditioner to help increase the mineral content of the soil and improve the soil’s structure and water retention capacity.

Heycarbons Maifan Stone Purification Principles and Mechanisms
Heycarbons maifan stone purifies water through adsorption and ion exchange, slow release of mineral elements, and filtration. Purification details are as follows:
Adsorption and Ion Exchange
Maifan stone possesses a naturally porous structure and a large specific surface area, enabling water purification through physical adsorption and ion exchange:
- Physical Adsorption: The porous structure effectively traps suspended particles, colloidal substances, and some organic pollutants in the water, improving water transparency and cleanliness.
- Ion Exchange: The surface of maifan stone contains active groups with a certain negative charge, allowing it to adsorb heavy metal cations in the water, such as lead (Pb²⁺), cadmium (Cd²⁺), and mercury (Hg²⁺), through ion exchange, reducing the concentration of harmful metal ions.
Slow-release effect of mineral elements
Maifan stone is rich in various natural mineral elements such as calcium, magnesium, potassium, sodium, and iron, which can be slowly released into water:
- Calcium (Ca) and magnesium (Mg): Regulate water hardness and improve the taste of water;
- Potassium (K), sodium (Na), and iron (Fe): Provide trace mineral elements, helping to improve the mineralization level of water bodies.
Filtration and Retention
As a natural mineral filter media, maifan stone particles form a physical filtration barrier in the filter layer, removing suspended solids, colloidal particles, and some impurities from the water through mechanical interception, sedimentation, and sieving, thereby improving the quality of the effluent.
