There is provided a method of preparing silica (SiO2) nanoparticles from siliceous mudstone which is silica mineral sources, using a chemical reaction. The method of preparing silica nanoparticles from siliceous mudstone comprises: solving a silica constituent into a sodium silicate aqueous solution by a sodium hydroxide leaching reaction of the siliceous mudstone (S100); performing ion exchange to remove a sodium constituent from the sodium silicate aqueous solution and to prepare a silicate aqueous solution (S200); and performing flame spray pyrolysis to prepare silica nanoparticles with an average particle dimension being in a range of 9 to 57 nm from the silicate aqueous solution. The present invention provides the method of preparing nanoparticles from siliceous mudstone by preparing the silicate aqueous solution from the siliceous mudstone by the chemical reaction and ion exchange process, and spraying the silicate aqueous solution being aerosolized and injecting generated liquid droplets of the solution into a flame reactor.

Disclosed herein is a uranium ion exchange adsorption method using ultrasound. The method includes placing a slurry obtained by mixing uranium ions, sulfuric acid and an ion exchange resin into a reaction bath, and stirring the slurry in the reaction bath while simultaneously applying ultrasound to the reaction bath to allow the uranium ions to be adsorbed to the ion exchange resin through ion exchange adsorption. The method has an improved ion exchange adsorption rate of the uranium ions.

A highly efficient uranium leaching method using ultrasound is disclosed. The uranium leaching method includes preparing black slate powder containing uranium by pulverizing black slate containing uranium, placing the black slate powder and water in a reaction bath, and performing uranium leaching by adding and mixing sulfuric acid and an oxidant with the black slate powder and water to prepare a mixture in the reaction bath while applying ultrasound to the reaction bath. In this method, uranium leaching efficiency can be maximized by adding sulfuric acid to the uranium ore while applying ultrasound thereto.
