Frequently Asked Questions

What is electrowinning of iron from SLS?

Electrowinning of Iron from Spent Leaching Solutions Using Novel Anion Exchange Membranes In the Pyror process, electrowinning (EW) is used to recover acid and iron from spent leaching solutions (SLS), where a porous Terylene membrane acts as a separator between the cathode and anode.

How to control the concentration of iron in copper electrowinning?

The conventional method for controlling the iron concentration has been to periodically or continuously bleed a portion of the iron-rich, copper-depleted electrolyte from the circuit and replace it with copper-rich electrolyte solution. In the copper electrowinning process, lead based alloys are used as anodes.

How does electrowinning work?

In electrowinning, a current is passed from an inert anode through a liquid leach solution containing the metal so that the metal is extracted as it is deposited in an electroplating process onto the cathode.

What is electrowinning in the pyror process?

DOI: 10.3390/membranes9110137 Abstract In the Pyror process, electrowinning (EW) is used to recover acid and iron from spent leaching solutions (SLS), where a porous Terylene membrane acts as a separator between the cathode and anode.
