| Abstract: |
| The abundant high-iron zinc-sulphide concentrate is treated by pressure leaching process,the laboratory test,semi-industrial test and industrial test have been finished,then industrialization production are executed based on pressure leaching technology.The industrial test results show the zinc leached rate is 98.05%,and the Fe leached rate is 29.22%,the remained acid in leachate is 39.15g/L,the iron content in leachate is 5.71g/L,that could be removed by the technology of sink alum. |
