How to choose the production process of aluminium sulfate

Aluminium sulfate has a wide range of applications in papermaking, water purification, etc., its production methods are also diverse. Generally speaking, there are methods of using bauxite and sulfuric acid; the preparation method of this method is relatively simple. There is also the method of using aluminium ash for production to avoid aluminium ash pollution of the environment and save resources. Additionally, there is the method of using kaolin to make it, which has a lower cost. However, what kind of production process should we choose when producing? Let's take a look at how to choose the production process with Xiaobian.

The following small series analyses the advantages and disadvantages of several various processes, which can be selected accordingly.
1. Because most of the enterprises in China used bauxite in production before, after a long time of such production, the current bauxite raw materials in China are gradually decreasing, and the quality of raw materials has decreased significantly. The quality of this production is not very good, so the number of companies that use this method of production is gradually decreasing.
2. The aluminium hydroxide process is relatively simple when it is produced, but because the process indicators cannot be strictly specified when producing with this method, the quality of aluminium sulfate is often unstable. Moreover, the price of aluminium hydroxide, the raw material used, is high, so only a few manufacturers use this method.
3. Aluminium ash can be produced in large quantities, but it does not have the slightest value in industrial applications.
4. The crude method of mixed consolidation production has been basically eliminated in China.
5. Alum ore has a high iron content. Therefore, using kaolin as raw material to produce is currently a relatively mainstream production process.

The above are the advantages and disadvantages of various production methods of aluminium sulfate. I believe that after reading the above comparison, we know how to choose the production process. We need to choose the right way to process and produce according to local conditions, and at the same time try to avoid polluting the environment and reduce the waste of resources.
