| 摘 要： | 通过焙烧实验探讨了含铊硫铁矿生产硫酸过程中铊的排放特性.结果表明,硫铁矿焙烧过程中,铊排放与焙烧温度、停留时间、焙烧气氛、硫铁矿的粒度等因素有关.不同的温度条件下,铊排放率不同,这主要是与矿石中铊的赋存形态有关;实验条件下,550℃—950℃是Tl排放的主要阶段,Tl排放量约占硫铁矿中总Tl的33.9%.Tl的排放率随... |

| Abstract: | In this paper,the characteristics of thallium emission during sulfuric acid production with Tl-containing pyrite roasting were investigated by roasting experiments in tube furnace.Results indicate that thallium emission was dependent on roasting temperature,retention time,roasting atmosphere and particle size of pyrite during pyrite roasting.Emission rates of thallium were different at different roasting temperatures,which were determined by the speciation of thallium present in the pyrite.Under the experim... |
| Keywords: | thallium pyrite roasting experiment influence factor characteristics of emission. |
