| Abstract: |
| For comprehensive recovery of valuable metals of marmatite processing to develop a solution containing iron pretreatment, simultaneous leaching of residues and marmatite, hematite precipitation and valuable metals recovery technology, obtained zinc recovery more than 96%, the iron removal rate above 93%, and containing 60%~65% iron, less than 0.5% zinc, 0.01% arsenic and 2% sulfur in hematite, which after processing can be used as iron making or in the production of cement and other raw materials, to solve the key technical problems of the traditional process don't adapt to deal with high iron solution and can't recovery residue containing iron, which realized the high efficiency comprehensive recycling of marmatite. |
