| titleOfInvention | A kind of refractory iron ore integrates mine tailing iron-extracting process |
| abstract | A kind of refractory iron ore integrates mine tailing iron-extracting process, and main technique is as follows：Refractory iron ore integrates mine tailing drying, broken up after processing, and magnetic mine tailing and nonmagnetic tailings are obtained with dry type weak magnetic separator magnetic separation；Magnetic mine tailing first carries out grading, and rejecting coarse fraction grade is relatively low, SiO 2 The high magnetic mine tailing of content, then carry out three sections of low intensity magnetic separation desiliconizations, Iron grade improved, so as to obtain qualified iron ore concentrate.Nonmagnetic tailings are first pelletized, dried, mixed again with coal reduction agent, loaded in mixture using rotary kiln into kiln magnetizing roast, 700 850 DEG C of sintering temperature, the 50min of high-temperature roasting time 30, complete after roasting, less than 100 DEG C are cooled to using indirect water-cooling mode, primary grinding, two stages of magnetic separation processing is then carried out, finally can obtain qualified iron ore concentrate.The more traditional tailings processing method of the invention is more purposive, carries out classification processing according to the heterogeneity of comprehensive mine tailing, can improve the disposal efficiency of mine tailing, so as to extract useful resources to greatest extent, realize the comprehensive utilization of refractory iron ore mine tailing. |
