The maximum quantity you can refine out of grains or casting scrap with a gold content of at least 55% every 6-10h is 1 - 20 kg of gold alloy with a final purity of 999.9/1000 (quantity depending on the size of the system).

KORAS® Gold Refining Tumbler TB

KORAS® Gold Refining Tumbler TB

This gold refining tumbler is a new technology compared to the static refining plants. This refining unit consists of a PPH-tumbler inclined to 30° and rotated by a motor, with the possibility to adjust the rotation speed. Thanks to the rotation forces, the gold grains continuously rub against each other and remove the silver chloride. This procedure reduces the complete dissolution time. The unit is available in different sizes from 2,5 kg to max. 360 kg output per production period.
