Rhotec™ Resins
Recover & Separate
Precious Metals
from PLS, leachates and waste streams.
High
Loading.
>50x
Since Rhotec loads 10-50 times more metal than existing resins while leaving undetectable PGM residuals, refiners use it to recover PGM from various pregnant leach solutions.
Loads 100% of its weight in gold.
Loads 40-50% of its weight in platinum or palladium.
Loads 30-40% of its weight in rhodium and iridium.
Sequential
Recovery
=Separation.
Loading Sequence
Rhotec loads metals in a specific sequence.
Metals are loaded one at a time.
The resin doesn't load the next metal until the current one is completely loaded.
Loading Capacity
Rhotec has a specific loading capacity for each metal.
Metals Separation
Precious metals can be partitioned and recovered one by one with high purity.
Use
Cases.
Aqueous Solutions & Streams
A wide variety of primary & secondary pregnant leach solutions, or industrial waste streams containing precious metals are ideal candidates. Rhotec is suitable for use with cyanide, chloride, and sulfate solutions.
Solvent-Based Streams
Under certain conditions, precious metals can be recovered from organic solvent-based streams.
Spent Plating Bath Solutions
Platinum and Palladium are easily recovered from used plating bath solutions in a variety of industries.
Catalyst Recovery
Precious metals can be selectively scavenged from leach solutions derived from spent heterogeneous catalysts, and under certain conditions directly from homogeneous catalysts.
