With this plant it is possible to obtain gold with a purity of 999,9/1000 starting from 900/1000 with a maximum silver content of 5 %.
Each 35 lt tank produces from 12 to 15 Kg each in 24 hours. the electrolyte solution should contain 80gr/lt of gold chloride. the plant consists of a single cell divided into two tanks, made out of self-extiguishing ppl, and resting on a safety tray. the refining cell is fitted with a suction manifold around its borders.
Aqua regia gold Refining Tumbler is a new technology compared to the static refining plants.
It is mainly a total different way to work. The static refining unit is an handicraft way to refine, the “Tumbler Machine” is an industrial way to ...
Introduction to Aqua Regia
The aqua regia refining process is used to refine gold alloys using a combination of acids and chemical products. The aqua regia solution consists of a mixture of hydrochloric acid HCL and nitric acid HNO3.
The refining process can be broken down into several steps:
The plant is used to refine alloys containing platinum, palladium and rhodium by aqua regia method. The maximum quantity with this plant is 1-2-5 kg / cycle. The cycle time is ...
It is entirely made out of self-extinguishing polypropylene (PPS) , with a transparent PVC protective door and complete with:
- Wash-basin with collection tank and storage container to drain to fluids and acids
- Electrical Heating Plate with adjustable power
- N° 1 filtration flask and vacuum system with dedicated valve
- N° 1 tap for demineralized water
- Accessories (Graduated Carafe, Buchner Funnel, Beaker, Filter Paper, Acid-proof Gloves ...)
The unit contains a series of selective resins to recover a wide range of pms from acidic solutions coming from aqua regia refining processes after cementation.
Using this type of equipment, the copper and ...
Copper electrorefining entails electrochemically dissolving copper from impure copper anodes into an electrolyte containing CuSO4 and H2SO4, and selectively electroplating pure copper from this electrolyte without the anode impurities.
It produces copper essentially free of impurities, and separates valuable impurities such as gold and silver from copper for recover as by products.
They are composed of:
Each cell is equipped with:
• level control
• Electrical contacts in stainless steel
The plant consists of modular units that allow the production of the very purest silver. Each tank can refine from 15 to 35 kg per day. Fast collection of the pure silver crystals discharged from the tanks. Fume extraction hood which allows easy installation of the anodes.
Electrolyte recycling pump which prevents unwanted deposits of silver on the anodes. Current rectifier with electronic voltage stabiliser.
This plant can refine silver coming from silver nitrate solutions getting a final purity of 999,0/1000.
It consists of:
• Cathodes and Anodes bars complete of all the relevant electrical contacts
• Stainless steel Cathodes.
• Trolley stirring mechanism provided with blades for ...
The refining process is chemical and is realized by a specific and rigorous procedure that uses base chemical reagents with low-pollution impact. The cylindrical reactor with agitator is appropriately ...
The plant of inquartation consists of a reactor by stainless steel or Pyrex glass, provided with a heating system (direct or indirect). The reaction time is comprised between 3-6 hours and the controlled addition of nitric acid helps to reduce the amount of nitrous ...
Silver Nitrate Salt Production process is carried out by the following steps:
A) Silver Dissolution by Nitric Acid
B) Nitrate solution Filtration
