以贵州晴隆大厂锑矿和甘肃西和崖湾锑矿冶炼厂废渣为研究对象,对采集的样品用XRF进行主量元素、XRD进行矿物表征和Tessier进行化学形态分析。研究了pH对Sb和As浸出的影响,分析了其机理。大厂和崖湾锑矿渣中Sb含量分别为5 447和24 666 mg/kg,As含量分别为472和240 mg/kg,废渣中的Sb和As主要是以残渣态的形式存在,可迁移态所占比例较低。pH对样品中Sb和As的浸出有较大的影响,不同pH下,样品的Sb和As浸出趋势具有明显的差异性,这与样品中矿物的溶解和元素在不同矿物上的吸附和解吸,以及元素的化学赋存形态有着重大的关系。 |

The smelting slags near Dachang antimony mines in Qinglong, Guizhou province and Yawan antimony mine smelter in Xihe, Gansu Province are collected for research. The collected samples were characterized by XRF, XRD and Tessier sequential extraction. The effect of pH on the leaching of Sb and As was studied, and the mechanism for the leaching of Sb and As was discussed. The results show that the contents of Sb in the slags of Dachang and Yawan antimony mines were 5 447 and 24 666 mg/kg, respectively, and those of As were 472 and 240 mg/kg, respectively. Sb and As existed mainly in the residual fraction. The leaching of Sb and As in the sample was significantly influenced by pH. At different pH values, the leaching of Sb and As differed significantly. This was suggested to be closely related to the dissolution of minerals, the adsorption and desorption of elements, and the chemical occurrence of elements. |
