Description of the unit

This gold refining tumbler is a new technology compared to the glass static refining plants. This refining unit consists of one PP-H tumbler with a total volume of about 21 liters, inclined to 27° and rotated by a motor, with the possibility to adjust the rotation speed.

Thanks rotation forces from the tumbler, the gold grains continuously rub against each other and remove the silver chloride. This procedure reduces the complete dissolution time. Inside the tumbler hood is a Schott borosilicate glass 3.3 condenser to condense the acid fumes reducing their volume.
The advantage of this construction is that we need a smaller fume scrubber. The transfer of the acid from the storage tanks is made by vacuum. This process can work without permanent supervision.
The maximum daily quantity to be refine every 4-8 hours is 2,5 kg of gold grains/chips with a final gold purity of 999,5/1000 (minimum). With this rotating gold refining system it is easy to refine gold grains, casting scraps and precious ashes.
