Entered the precious metal refining industry in 2005 and mastered the domestic gold electrolytic refining and extraction gold refining process and equipment.
In 2007, we independently developed the gold aqua regia wet refining process technology and refining equipment to improve production efficiency and reduce the loss rate of precious metals.
In 2009, he mastered German gold refining technology, silver refining technology, Austrian platinum and palladium refining technology and related precious metal refining process equipment.
In 2010, we independently developed, designed and used the first-generation double-layer glass reactor for gold refining equipment and process improvement.
In 2012, we independently developed and designed the golden aqua regia wet refining equipment and chemical wet purification process using the first-generation double-layer titanium reactor.
From 2015 to 2020, combined with the actual production situation of the factory, we will continue to optimize the independent research and development of the second-generation double-layer titanium reactor aqua regia wet gold refining equipment and the improvement of the installation process, and further research equipment automation control and intelligent factory equipment and continue to innovate!
