Iron Control

Approximately 50% of the world’s copper is produced by Solvent Extraction and Electrowinning. During the solvent extraction process, copper is transferred, via an oxime extractant from the leach solution, to the copper electrowinning electrolyte. Small amounts of iron are also transferred with the copper, due to a small degree of chemical loading and physical entrainment …

Fixed Bed Ion Exchange

Fenix Hydromet has developed design criteria for ion exchange plant by undertaking testwork at laboratory and pilot scale, providing our IX equipment where appropriate to the client’s requirements.  We have in depth knowledge of the suitability of different ion exchange media for specific applications, depending on the concentrations and combinations of elements in the solutions …

Fluidised Bed IX

Fixed bed ion exchange can be susceptible to blockage due to the presence of solids in the feed solution. To overcome this issue, without the need for expensive solid/liquid separation,  ion exchange may be operated as fluidised beds such as taking feed solutions straight from heap leach operations. Specialised column designs are required, and are …

Resin in Pulp/Resin in Solution

Resin in Pulp (RIP) is already commonly used commercially for the recovery of gold cyanide and uranium, the technique is particularly well developed and widely used in the former Soviet States.  RIP has the main advantage over fixed bed ion exchange in that it uses open tanks rather than much more expensive pressure vessels. There …

Multi-media Electrolyte Filters

At Port Pirie  in South Australia, Nyrstar operates a Solvent Extraction (SX) and Electrowinning (EW) circuit for the production of copper cathode.  In the operation of this circuit organic reagents from the SX circuit are transferred to the electrolyte in the EW circuit.  This transfer is undesirable from a number of perspectives, as it can …
