Maifan stone, also known as medical stone, is a precious natural silicate mineral formed through millions of years of volcanic activity and geological evolution. Mainly composed of quartz, feldspar, biotite and amphibole, it contains over 50 kinds of elements and trace elements essential to living organisms, including calcium, magnesium, potassium, zinc, selenium and iron. Processed via crushing, purification, ultra-fine grinding and precision classification, maifan stone powder inherits the original porous structure, strong adsorption capacity, excellent ion exchange performance and slow-release mineral characteristics of raw ore. As a non-toxic, non-radioactive and eco-friendly natural mineral material, it has been widely applied in drinking water purification, industrial wastewater treatment, aquaculture, air deodorization and ecological restoration across the globe. With the rising global demand for green environmental protection and safe water resources, maifan stone powder has become a core eco-material driving the upgrading of the environmental protection industry and sustainable water resource management.
The most prominent advantage of maifan stone powder lies in its comprehensive water treatment performance integrating purification, mineralization and pH regulation. Its developed microporous structure (pore size 5–10 nanometers) acts like a natural adsorption sponge, effectively intercepting suspended solids, organic pollutants, residual chlorine, bacteria and harmful heavy metals such as lead, cadmium, mercury and arsenic in water, with a heavy metal removal rate reaching 89%–94%. Different from single-function synthetic adsorbents, maifan stone powder can continuously dissolve and release beneficial minerals while removing pollutants, turning ordinary water into weakly alkaline mineral water with a stable pH value of 7.5–8.5. This characteristic perfectly solves the problem of mineral loss in reverse osmosis and distilled water, effectively improving water activity and drinking taste, and helping maintain the human body’s acid-base balance. In municipal tap water purification, rural scattered drinking water projects and bottled water production lines, maifan stone powder serves as an ideal natural filter medium, reducing the use of chemical flocculants and additives, and realizing low-carbon and green water treatment.
In industrial wastewater and aquaculture water management, maifan stone powder shows irreplaceable practical value. For printing and dyeing wastewater, electroplating wastewater and mine drainage containing complex pollutants, it can adsorb organic dyes, toxic ions and residual chemicals, reduce water turbidity and chroma, and lower the discharge concentration of pollutants to meet national and international emission standards. In aquaculture ponds, fish tanks and shrimp farming systems, long-term use of maifan stone powder stabilizes water quality, reduces ammonia nitrogen and nitrite content, inhibits the reproduction of harmful algae and pathogens, and significantly improves the survival rate and growth rate of aquatic products. Meanwhile, the released trace minerals provide natural nutritional supplements for aquatic organisms, reducing the dosage of chemical fish drugs and feed additives, and promoting the development of ecological and healthy aquaculture. Compared with traditional water treatment agents, maifan stone powder will not produce secondary pollution after use. It can be regenerated and reused through simple cleaning and sun exposure, greatly reducing the long-term operation cost of enterprises and farms.
Beyond water treatment, maifan stone powder is widely used in air purification, deodorization and food preservation. Its strong adsorption capacity can effectively absorb formaldehyde, benzene, ammonia and other harmful gases in indoor environments, as well as peculiar smells in refrigerators, warehouses, livestock houses and garbage stations. As a natural deodorant, it is safe and durable, free of chemical residues, and in line with the global pursuit of healthy living environments. In the food and beverage industry, food-grade maifan stone powder is used as a natural additive and fresh-keeping agent. It can maintain the flavor and nutrition of foods such as fruits, vegetables, grains and fermented products, extend the fresh-keeping period, and supplement trace elements for food. It has been widely used in the production of mineral water, beverages, wine, soy sauce, vinegar and baked goods, winning high recognition from food manufacturers for its safety and functionality.
Our company specializes in the production and supply of multi-grade maifan stone powder, with complete specifications ranging from 325 mesh to 6000 mesh.

FAQs of Maifan Stone Powder for Environmental & Water Use
Is maifan stone powder safe for drinking water and food contact?
Yes. It is a natural inorganic mineral, non-toxic and non-radioactive, compliant with international food safety and environmental protection standards, and safe for long-term use in drinking water and food industries.
How long is the service life of maifan stone powder in water treatment?
Under conventional use, it can be used continuously for 1–2 years. Regular cleaning and sun exposure can regenerate its adsorption capacity and extend the service life.
What is the difference between maifan stone powder and activated carbon?
Maifan stone powder integrates purification, mineralization and pH adjustment, and can release beneficial minerals; activated carbon only focuses on adsorption and has no mineral supplementation function.
What specifications can you provide?
We supply 325 mesh, 800 mesh, 1250 mesh, 2000 mesh to 6000 mesh products, and support customized fineness according to customer requirements.
Do you support bulk orders and global delivery?
We have stable bulk supply capacity all year round, provide various packaging solutions, and cooperate with professional logistics teams to realize timely delivery worldwide.
