- In the "Development of an innovative noble metal / rare metal recovery system using organic aqua regia" carry out by the Ministry of the Environment Environmental Research Comprehensive Promotion Fund, noble metals are extracted with organic aqua regia from powders containing noble metals. At that time, It is looking for a method of stirring the powder without mechanical destruction.
Noble metal / rare metal recovery system using organic aqua regia
National University Professor
Extraction of noble metals using organic aqua regia
Achieves prevention of powder destruction and improvement of extraction efficiency.
- It is possible to stir the powder without mechanical destruction.
- Since it becomes possible to heat the temperature to 80 ° C. or higher using an organic solvent, the extraction efficiency is increased.

By using SEALING MIXER UZU and the centrifugal stirrer, the stirring efficiency of liquids including solids is improved.
Due to the stirring flow from the bottom, it is possible to disperse the powder in the liquid without damaging it.
In addition, the liquid surface can be kept calm, minimizing the scattering of solution and the entrainment of air.
It is ideal for stirring processing that includes a solid phase and reaction that involves precipitation.
Since it is composed of PTFE, it has high corrosion resistance.
Highly corrosion-resistant materials such as PTFE are used for the liquid and gas contact parts.
It is possible to use for various chemicals.
It can be easily disassembled and washed after use.
It can prevent the contamination of residue.
