KORAS® Gold Recovery System GRC
The GRC Gold Recovery System is especially to recover gold from grinding and polishing sludge, scraps, sweepings and ashes. As a matter of course the recovery of gold from solutions such as rinsing baths, polishing baths etc. is also possible.
It consists of a completely new concept of a dissolving unit and an electrolytic cell. In one step, the precious metals can be recovered directly from the above mentioned waste.
The dissolving at room temperature additionally saves energy costs.
KORAS® Electro-Polishing Machine Aqua-Pol®
Electro-polishing is the most gentle and cleanest way to give jewelry pieces a pure surface, for further process. The new Aqua-Pol® compact system achieves this quickly and economically with precision and only requires little space. Furthermore KORAS® has developed process liquids whose qualities are considerably superior to standard electrolyte. Effectiveness in a wide range of applications, easy handling and a long service life – the electrolyte from Koras GmbH achieves measureable advantages.
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.
especially for small parts Electro-polishing is the most gentle and cleanest way to give jewelry pieces in an industrial production process a smooth, ultra-pure surface, for further processes. Our Aqua-Pol ® product lines achieve this very efficiently with precision and the system require...| » Further reading
