The production process of industrial grade aluminum sulfate is to prepare bauxite through a series of preparations, then add sulfuric acid to form aluminum sulfate, and finally obtain industrial grade aluminum sulfate. The following is a specific case introduction.

1. Selection of ores: Aluminum-containing ores are collected from the mines. After crushing, grinding, screening and other processes, aluminum-containing gallstones, hematite and other extracts are selected to obtain high-purity aluminum phosphates.

2. Bauxite smelting: After smelting and cooling the bauxite, aluminum-containing aluminum slag and aluminum sodium are obtained.
Silicon material.

3. Sulfuric acid leaching: Put aluminum slag and aluminum-siliceous materials into the solution respectively, add concentrated sulfuric acid for leaching and react to obtain an aluminum sulfate solution.

4. Precipitation: Precipitate the impurities in the aluminum sulfate solution to purify the solution. During this process, it is necessary to control the precipitation reaction conditions, which mainly include factors such as temperature, acidity, and stirring speed.

5. Filtration and drying: Filter the aluminum sulfate particles obtained after precipitation to separate the useless solution and solid aluminum sulfate. The solid aluminum sulfate is dried to remove moisture to obtain industrial grade aluminum sulfate.
