:: Metallurgical Testwork Results Show Potential to Treat Full Laterite Profile  

Weda Bay Minerals Inc. (WDA) previously announced very encouraging metallurgical testwork results on the incorporation of atmospheric leaching into its process flowsheet to treat the extensive saprolite resources. The aim of this testwork was to further develop a combined Pressure Acid Leach (PAL), Atmospheric Leach (ATL) and Saprolite Neutralization (SN) process flowsheet. This integrated flowsheet (PAL/ATL/SN) will enable Weda Bay to treat the entire laterite profile of limonite and saprolite. Testwork also confirmed the benefits of using seawater in place of fresh water in the process flowsheet. Lakefield Oretest Pty Ltd in Perth, Australia conducted the testwork.
