The study’s reagent and operating cost reductions along with forecast capital savings will be confirmed in the Etango definitive feasibility study update.
The membrane study tested the effectiveness of five different membrane types on two different solution streams, both generated from the Etango heap leach demonstration plant.
Results enhance Etango economically and operationally
Bannerman’s chief executive officer Brandon Munro said: “The amenability of the Etango Project to recent advances in established nano-filtration technology is an exciting outcome that further confirms the robust economics and low technical risk of the Etango project.
“Our technical team undertook the membrane study diligently and comprehensively, utilising the unique advantages Bannerman’s heap leach demonstration plant offers, in particular the access to industrial-scale uranium bearing solution generated from the Etango orebody.
“I am delighted that this success further enhances Etango, both economically and operationally, as a world-class, highly-advanced and strategically important uranium project.”
In late 2017 a membrane pilot test rig was mobilised to site to undertake an initial test work program, which is now complete.
The membrane test work undertaken successfully demonstrated the ability of the nano-technology to recover acid for re-use and upgrade the uranium concentration in the solution almost ten-fold.
The extent of forecast operating cost reductions and capital savings will be known following definitive engineering associated with the DFS update.
