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 other Bm sludge produced during precipitation/cementation with soda/lime are basically free of precious metals.
The selective resins are able to recover gold, platinum, palladium, rhodium and mercury but allows silver to skip through thus lengthening the life-span of the resins.
These resins can capture up to 40-50 g of precious metals per litre and can’t be regenerated. precious metals are recovered by incineration.
