摘要

砷在成矿过程中经常与其它金属伴生

其化合物在焙烧冶炼过程中易与其它金属形成冶炼烟灰

此类含砷烟灰具有毒性及挥发性

安全堆存已成为冶金企业面临的难题

对含砷烟灰进行物相分析

从而确定其成分及其砷含量

可为进一步处理该类烟灰

使其达到环保部门的堆存要求提供重要依据.本文选取砷滤饼

对其分别进行物相分析和脱砷研究

得知砷滤饼样品中As元素含量为13.07%

并以As2O3形式存在

样品中还含有Cu、Pb、Zn等金属及其氧化物和9.8%的S元素.根据以上物相分析结果

进行了砷滤饼样品碱浸脱砷动力学研究

比较白烟灰样品中As元素在一定温度范围内的浸出速率

结合浸出动力学分析结果

得出在303 K～343K范围内

样品中的As在碱浸体系中为内扩散控制的结论

该反应动力学属于未反应收缩核模型.基于以上分析

本文提出碱浸脱砷方法

采用Na OH+Na2S碱浸脱砷

As浸出率高达96.5%

Cu、Pb、Zn金属浸出率低

实现了As与这些金属的有效分离.

Abstract

Arsenic often accompanies by other metals when mineral generates.Its compounds form smelting dusts with metal during the process of roasting.Because of its toxicity and volatilization

secure stockpiling of arsenic dust has become a big problem for those metallurgical enterprises.The composition and arsenic content of arsenic dust which decided by phase analysis will provide some important information

it will help to handle the ash

and make it satisfy environment requirement.In this paper

the chemical states and content of various elements were determined

and arsenic removal techniques were presented in the As-filter cake sample.The results show that the content of As is 13.07% and occur as As_2O3.Besides As

there are Cu

Zn and their metal oxides and 9.8% S in the sample.Based on the above phase analysis results

the alkaline leaching kinetics of removing arsenic were investigated.In the system of NaOH+Na_2S

the leaching rates of arsenic were compared from 303 K to 343 K

the results show that the inner diffusion is the controlling step in the leaching of arsenic in NaOH+Na_2S system

and the kinetic equation follows the unreacted shrinking core model.Based on the above analysis

the alkaline leaching arsenic removal technique in NaOH+Na_2S system was development

the leaching ratio of arsenic was run up to 96.5%

the leaching ratio of Cu

Pb and Zn is low

then separation of arsenic from valuable metals were realized.
