Pregnant Solution Recovery
Pregnant Solution Recovery
Well-designed and optimised pregnant recovery circuits enhance the energy efficiency of mineral processing flowsheets.

Mineral-bearing pregnant solutions contain gold and/or silver. They are produced from intensive cyanide leaching.
There are a variety of pregnant solution recovery methods available to isolate precious metals. Choosing the most appropriate is essential for maximising mineral recovery.
The conditions used in upstream processing, to generate the pregnant solution, play an important part in determining the best mineral recovery technique. In addition, knowing if the pregnant solution has a high or low-grade metal production rate will help to determine the optimal pregnant solution recovery method to use for a given allocated budget.
In general, Gekko design pregnant recovery circuits as part of an overall energy-efficient mineral processing flowsheet.
