Abstract: The Carlin-type refractory gold ore in Jinshan Gold Mine in Naban possesses invisible gold and extremely inaccessible leaching nature,so ultrafine grinding-stirring leaching,grinding while leaching-stirring leaching,grinding while alkaline leaching and ambient temperature and pressure enhanced alkaline leaching pretreatment-stirring leaching processes are studied.The results show that the ultrafine grinding-stirring leaching process can only achieve gold leaching rate of 56.96 %;the grinding while leaching-stirring leaching process can reach the gold leaching rate of 61.81 %;the grinding while alkaline leaching and ambient temperature and pressure enhanced alkaline leaching pretreatment-stirring leaching process can effectively recover the gold from the gold ore.Under optimized conditions,the gold leaching rate can be increased to 94.17 %;to effectively recover the gold from the ore,it is essential to do ultrafine grinding and proper pretreatment.The research results can be used as reference for highly efficient recovery of gold from Carlin-type refractory gold ores.
