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。

Analogous complexes 3a" and 4a"= CpRu(PPh32, Ar = para-C6H4OMe containing methoxy group at the para-position of gem-diphenyl group were similarly obtained from protonation of the corresponding acetylide complexes via formation of vinylidene intermediate. But only complex 3a'= CpRu(PPh32, Ar2 = fluorenyl is stable in solution, and decomposed to unidentified complex when heated to reflux in THF. Deprotonation of complex 4a in the presence of base gives neutral acetylide complex 6a.
