To any mets/operators reading my 2c worth, There is not much "gravity gold" at Wiluna as others have said. the flash floatation gets out most of the gravity recoverable gold. BIOX does liberate some free gold. Every new generation of mets on site does a bit of testwork (sending tails samples off site, getting a Knelson on site, etc). They all come to the same conclusion, there is not a lot of gravity recoverable gold at Wiluna. AMMTEC have probably made a lot of money from repeat testing Wiluna samples. There may be a point for having a Knelson gravity circuit after the BIOX and the cyanide leach, to recover some liberated gravity gold before it goes to tails, and that did exist in Agincourt days I believe and Apex took it away.
