This approach not only significantly reduces labor and energy costs but also enables substantial cost control. Moreover, it features simple and easy-to-master production processes, making it highly favored by a wide range of water purification agent manufacturers. Here, Xintai Group’s bauxite manufacturer would like to share with everyone a cost-effective method commonly adopted by water purification agent producers: using low-cost bauxite and calcium aluminate powder as raw materials to manufacture polyaluminum ferric chloride—this is provided solely for reference!
Xintai Group’s calcium aluminate powder, now used as a water purification agent, offers a cost-effective method for producing polyaluminum ferric chloride using alunite and calcium aluminate powder. The technical solution of this invention involves producing polyaluminum ferric chloride from bauxite and calcium aluminate powder as follows: First, 0.8 to 1.3 tons of industrial hydrochloric acid with a concentration of 10–30% is heated to 40–130°C. Then, 0.3 to 0.6 tons of alunite are slowly added, followed by 0.1 to 0.3 tons of aluminum sulfate and 0.05 to 0.1 tons of hydrogen peroxide. After maintaining the temperature and allowing the reaction to proceed for one hour, 0.2 to 0.4 tons of calcium aluminate powder are added and the mixture is allowed to react further for another 2–3 hours. Finally, 0.05 to 0.1 tons of potassium permanganate solution with a concentration of 1%–10% are added, and the mixture is left to stand undisturbed for 1–2 hours, yielding liquid polyaluminum ferric chloride.
Calcium aluminate powder used as a water purification agent is a grayish-white powder composed of a mixture of calcium dialuminate (CaO·2Al₂O₃) and calcium monaluminate (CaO·Al₂O₃). It is slightly soluble in water, and its aqueous solution exhibits alkaline properties with a pH value of approximately 11. It is an important raw material for water purification agents and currently serves as an excellent feedstock for the production of basic aluminum chloride and polyaluminum chloride products.
The raw material used for producing polyaluminum chloride—a water purification agent—by means of aluminum alumina is light-burned aluminum alumina, also known as light-burned powder. It is a fine mineral slag powder obtained through the processing of aluminum alumina, with trioxide of aluminum as its main component. This material contains impurities in the form of hydrated aluminum oxide and is classified as an earthy mineral. It appears milky white or grayish-white, but may turn brownish-yellow or pale red due to the presence of copper. Its density ranges from 3.9 to 4 g/cm³, its hardness is between 1 and 3, it is transparent, and has a brittle texture. It does not melt easily, is poorly soluble in water, but can dissolve in hydrochloric acid and sodium hydroxide solutions.
Overall, combining bauxite with calcium aluminate powder is an excellent approach for producing polyaluminum ferric chloride—a water purification agent. This information is provided for reference only; for specific values and key parameters, it is recommended to consult with a team of qualified technical experts.
