● in 1979 we installed the first chemical gold refining and gold recycling system and increased efficiency to 98 %.
● in 1985 we introduced the first carat control unit which could make rapid carat control using potentiometric titration.
● in 1996 we developed the recycling systems which were our own invention, and produced the recycling and refining machine of today
This gold recycling & gold refining machine can recycle precious metals like gold, silver, platinum, palladium and rhodium without producing any smell or smoke.
● Since 2004 we started exporting our products. My websites: gold refining
