Hydrometallurgy
 

Purolite® products are utilised in the recovery of Uranium, Gold, Molybdenum, Rhenium, Nickel, Copper and other valuable metals.

Purolite has a range of products tailored for all methods of industrial hydrometallurgy. Such methods comprise the following:

  • Sulfuric acid and (bi-)carbonate leaching of uranium
  • Metals recovery from “clarified” solutions; either Heap Leaching (HL) or In-Situ-Leaching (ISL) operations
  • Uranium, gold and basic non-ferrous metals sorption from pulps; i.e. “Resin-In-Pulp” (RIP) and "Resin-In-Leach" (RIL) operations.
  • Extraction of various low level values from pulps and solutions. 

We work closely with customers from around the world to improve recovery and productivity using highly selective resins.  Technical demands from our customers  are matched to high performing specialty resins and supported by our technical experts.  

In the table below we present several examples of usage of Purolite products in some specific applications. Actual product choice may vary from case to case depending on characteristics of particular operation. Please contact your local Purolite Office to discuss your specific requirements in greater detail.
