| titleOfInvention | Method for producing silica-based aggregation liquid |
| abstract | (57) [Summary] [Objective] Not only does it have no problem with Al-based aggregates, Fe-based aggregates, and polymer-based aggregates, but it also produces a foul odor during or after the dissolution of silica composite crystalline minerals / amorphous minerals It is an object of the present invention to provide a method for producing a silica-based coagulating liquid that can prevent not only the generation of sulfuric acid but also the corrosion caused by the generation of sulfuric acid. [Structure] According to the production method of the present invention, after dissolving unoxidized sulfur-removed silica composite crystal mineral / amorphous mineral with diluted sulfuric acid, The solution is brought into contact with activated carbon or an anion exchange resin to remove anions, or Ca 2+ is added to the solution to produce calcium sulfate to remove sulfate radicals or silica. When dissolving the complex crystalline mineral / amorphous mineral with dilute sulfuric acid, activated carbon is added, and then the dissolved solution is contacted with activated carbon or an anion exchange resin to remove anions, or Ca is dissolved in the dissolved solution. 2+ Is added to produce calcium sulfate to remove sulfate radicals. |
