| titleOfInvention | A kind of refractory iron ore suspension roasting dry type preliminary rejection is returned mine furnace method of roasting again |
| abstract | The invention belongs to technical field of mineral processing, it returns mine furnace method of roasting again more particularly to a kind of refractory iron ore suspension roasting dry type preliminary rejection, the method steps are as follows: will be crushed to the dry grinding of 0-15mm granularity refractory iron ore or wet-milling is dried to -200 mesh and accounts for 45-50%, fluidization magnetizing roast is carried out using shower furnace, roasted ore is cooled to 70-80 DEG C, feed the pre-selection of screw dry magnetic separator dry type, pre- concentrate selection enters mill and selects system, preliminary rejection enters shower furnace magnetizing roast again of returning mine, it is likewise cooled to 70-80 DEG C, feeding screw dry magnetic separator, dry type preselects again, pre-selection, which progresses greatly, selects system into mill, tail is preselected to be discharged by qualified tailings, entering furnace magnetizing roast present invention is generally directed to the wide size fraction ranges of refractory iron ore causes roasted ore quality uneven, cause to sort tailings grade higher, in the presence of The not high problem of resource utilization, after refractory iron ore is handled by closed circuit method of roasting, metal recovery rate can be improved 15 percentage points or more. |
