Owning the Diatomite mineral mine with large reserves and the best quality in Vietnam, Area more than 200 hectares; Reserve more than 20 million tons. Vietnam Diatomite produces and supplies applied products in many fields..
With the characteristic properties: light, porous, heat-resistant, good stability in alkaline and acid environments. Diatomite has been used in construction materials industry from 1870 to 1900.
Diatomite’s specific applications in the field of building materials in the world are used by the United States, Japan, and China: Additives for cement production, lightweight concrete, asphalt concrete, room partitions, ceilings and interior paint.
Diatomite filter aid powder has the basic form of coarse powder, unique pore structure, different particle sizes, stable chemical properties and strong adsorption capacity. As a result, the diatomite filter aid powder is the perfect solution to significantly improve the filtration efficiency and clarity of the filtered object, improve production efficiency, and minimize the cost of filters. Currently, diatomite filter aid powder is widely used in many types of liquid separation filters.
The chemical composition of diatomite is mainly SiO2 with the general formula SiO2.nH2O. In addition, the diatomite also contains a small amount of agglomerate Fe, Ca, Mg, K, Na … The pure diatomite is usually white in color. In nature, often contains impurities, so they are gray, light yellow, gray to black, the darker the amount of impurities. Diatomite has white streak, light, many holes, fragile into soil, however the hardness can reach 4.5 ÷ 5. Melting temperature is 1,400 ÷ 1,650oC. Only soluble in HF acids and alkalis. The porosity of diatomite is large, can absorb 1.5 ÷ 4.0 times the amount of water compared to its own weight. Diatomite’s typical pore texture is manifested by the pore density and diameter parameters..
Because of its long cylindrical, elongated, very porous crystal structure with good adsorption capacity, it is used in industries: industrial wastewater treatment, aquaculture, as filter aid. in alcohol, cooking oil, animal feed, fertilizers and soil amendments.
GEOGRAPHY AND EXPLOITATION AREA
Diatomite mine is located in Hoa Loc area, An Xuan ward, Tuy An district, Phu Yen province, 12km far from National Highway 1A and 40km north of Tuy Hoa city. Traffic in the operation area and the factory is provincial road 650, so it is easy to transport goods by rail at Chi Thanh station 12 km away from the exploitation area and by sea at Quy Nhon port 85 km.
Diatomite mine is divided into two zones with a total area of more than 200 hectares, of which the mining area has a total area of more than 100 hectares.
