Platinum, palladium and gold leaching from

Platinum, palladium and gold extraction from a magnetite concentrated ore Leaching tests at 20 °C, with concentrated chloride solutions and ozone sparging at pH 4 and ore size fraction 74–149 μm Download : Download fullsize imageFor testing, I've been digesting material in aqua regia This was ok to verify presence of gold and to get some idea of its concentration However, I have to admit that this has been a very inefficient process Multiple days of AR treatment of small samples (few tablespoons) of test material results in only partial gold extractionRequest for info, extracting gold in/on magnetite

Fine Gold Recovery Separating Placer Gold Particles
