Abstract: JZ)Henan gold with more wrapped in gold and even the golden,more difficult to choose.By flotation,slime cyanidation of the ore and flotation+flotation concentrate cyanidation three kinds of the process of comparison,finalize the ore "Slime cyanidation of the ore" or " flotation+flotation concentrate cyanidation" process to recover gold."Slime cyanidation of the ore" process has been:the grinding fineness of -200 mesh 60%,cyanide 8 hours when,the leaching rate of gold reached 95.31%;"Flotation+flotation concentrate cyanidation process has been:and then pulverized degree 200mesh 90%,cyanide eight hours,the leaching rate of gold is 95.99%,the gold recovery rate is 83.66%.
