The invention discloses a synthetic using method of smelting high-furnace dust, which comprises the following steps: grinding the high-furnace dust with 1.5-15% zinc; proceeding magnetic cobbing; reclassifying to obtain the refined ferric ore; disposing ore tail through waste acid of titanium dioxide with 15-30% sulphuric acid; transmitting the zinc oxide in the solution at zinc sulfate pattern; separating solid and liquid solution through lime; obtaining refined zinc ore through S2-, CO32-, HCO3- ion; floating the immersed slag through neutral oil.

一种炼铁高炉炉尘资源综合利用的方法，含锌1.5％～15％的高炉炉尘经磨矿、磁选、重选回收铁矿物获得铁精矿，选矿尾矿用含硫酸15％～30％的钛白废酸处理，使其中的氧化锌以硫酸锌的形式转入溶液中，固液分离得出的溶液用石灰中和除铁后，再用S2-、CO32-、HCO3-离子沉锌获得锌精矿，浸出渣用中性油浮选获得炭精矿。该方法将钛白废酸和高炉炉尘结合在一起，使之成为互为所需的原料和试剂，有效地将两种废弃物变成了有价资源，较好解决了环境污染问题，同时又能产生好的经济效益。

Due to the finer size and little dense difference between Perovskite and Titanaugite, shaking table was employed as the main equipment of gravity separation. The ground products were screened four classifications. Some qualified tailings could be cast away in the coarser fractions, which could decrease disposal quantity of the next step-floatation.

对实际改性渣进行了选择性分离，基于相对较细的粒度和二者密度相差较小的事实，选择摇床为重选设备，并采用分级入选的方式，在较粗级别可抛弃部分合格尾矿，减少磨矿和下一步重选或浮选作业的处理量。
