BRAVor® is able to selectively recover precious metals from plating bathes, washing solutions and rinsing waters.
BRAVor® gives the customers the following benefits:
- Allow the customers to keep their gold inn.
- Recover precious metals down to few ppms.
- Recover up to 5 g/h of precious metal.
- Has no moving parts.
- Minimum maintenance.
- No chemical additives required.
- Labour is essentially limited to harvest precious metals.
Here follow the main applications:
- Earn Gold – from cyanide and chloride solutions
- Earn Rhodium – from sulphate solutions
- Earn Silver - from nitric and cyanide solutions.
- Earn Platinum, Palladium, Rutenium, Iridium and other metals.
BRAVor® refers to the following processes:
- JEWELLERIES
- GALVANIC SHOPS: Exhausted bathes
Jewellers use to immerse the pieces after plating process in water, in order to clean the surface by precious metals in two operations, descripted as follows:
During the first washing step, the precious content increases and the solution has to be renewed once the "precious" concentration in water achieve a certain value (say 0,5~1 g/l).
The "precious solution" can be treated with BRAVor® to recover pure Gold.
Gold recovery from Cyanides Primary Washing bathes
Silver from nitrate media
Rhodium from Sulfates
Rhodium bath is used in jeweler’s craft to give the white gold alloy a brilliant aspect. Bath composition is normally around 2 g/l of Rhodium Sulfate in trivalent valence When a grade of contaminants, in terms of metal ions (Fe, Cu …), affects the quality of the rhodium plated, the bath is considered exhausted, but also contains a high level of precious metal.
An exhausted rhodium bath can be treated directly with BRAVor® to recover pure Rhodium metal.
