摘要
对河南省某金矿进行了LSSS法添加氯化钠在常温下的浸取条件研究 ,当LSSS中的液固比在 3∶1时 ,[NH3] =0 .5～ 0 .8mol/L ,[NaCl] =0 .8mol/L ,温度在 2 5℃ ,浸取时间为 3h ,浸出率可达到 94%以上 ,从而实现了在常温下、低 [NH3]浸取金的目标 。
The optimization of conditions of leaching gold from ore in Henan province with LSSS solutions added NaCl has been explored.The leached fraction of gold can go up to 94% with solution of L/S=3∶1,[NH 3]=0.5～ 0.8 mol/L ,[NaCl]=0.8mol/L at 25℃ for 3h. Consequently,attain the object of leaching gold under the conditio of low [NH 3] and normal temperature;on the other hand,the cost of production was reduced.
