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。

In order to study degradation of potassic mineral by fungi, we isolated a thermophilic fungi strain TH003 from compost. The strain can use extract potassium from rocks as a nutrient. The strain was identified as Aspergillus fumigatus based on its morphological characteristics and molecular result.

为研究真菌对含钾矿物的吸附降解作用,作者从高温堆肥中分离选育出了一株丝状真菌TH003菌株,通过在含有矿物颗粒的改进PDA培养基中培养,使其在培养液中与矿物颗粒发生作用,再取样进行电镜观察和X-射线衍射分析以及电子探针观察。

Widespread iron bacteria itself to the role of Concentrations, and allows a variety of ferrous oxide reduction in the role and dissolved minerals precipitate role in the formation of different iron minerals and mineral nature of the changes significantly affected the soil and water geochemical characteristics.

广泛存在的细菌本身对铁具有富集作用,并可使各种含铁矿物发生氧化还原作用和溶解沉淀作用,形成不同的铁矿物并导致矿物性质的变化,极大地影响了土壤和水体的地球化学特征。
