PRECIOUS METALS RECOVERY
The recovery of precious metals from scrap material generated by manufacturing or chemical processes represents an extremely important activity in the economy of business activities.
IONS EXCHANGE RESINS PLANTS
Ion-exchange resin plants are used for the recovery of precious metal particles present in effluents of the aqua regia refining process.
The liquid is treated within specific selective resin columns that capture precious metals (gold, silver, platinum, palladium and rhodium).
The efficiency / selectivity of the process is appreciable based on the type of resin used, among the various available on the market.
|Columns constructive material||Borosilicate glass||Polypropylene|
|Processing capacity||80 L/ora||100 L/ora|
ELECTROWINNING – ELECTROLYTIC RECOVERY
Electrolytic recovery cell (electrowinning): it easily recovers the precious metals dispersed in the basic and acid solutions.
The operating principle is based on the electrowinning technique, an electrochemical process that is carried out inside an electrolytic cell in which the metal, dissolved in solution, is extracted depositing on the cathode. The passage of current inside the solution in fact determines the deposit of the metal on a specific support.
- Easy to use
- No supervision required
- No installation service required
- Minimum maintenance
- High recovery efficiency
- Rapid return on investment
The machinery finds applications in various sectors: goldsmith / silversmith, galvanic, mining.
|Usage||Basic solutions||Acidic solutions|
|Processing capacity/cycle||200 – 400 L|
|Catodes / anodes||Min 1 catode / 2 anodes
Max 3 catodes / 4 anodes
|Power supply||220 V 50 Hz single phase|
The two models differ in construction materials, according to the kind of usage: on acidic solutions or on basic solutions
