In order to achieve utilization of antimony and alkali in arsenic-alkali slag and solidification of arsenic, a new processing technique, consisting of separation antimony by water leaching, arsenic precipitation by hydrothermal reaction with lime, and alkali extraction by evaporation, was proposed to treat arsenic-alkali slag. Results show that water leaching at 90 ℃ for 5 h with liquid-solid ratio of 3∶1 can result in the leaching rate of arsenic up to 97.96% and the leaching rate of antimony just 0.72%. The obtained leaching residue only contains 0.09% arsenic, presenting effective separation between antimony and arsenic. With calcium and arsenic in a molar ratio of 1.43, hydrothermal reaction at 170 ℃ for 2 h can lead to an arsenic precipitation rate up to 99.68% and the solution after precipitation with arsenic and alkali in a mass ratio of 1.65‰, also presenting a good separation effect. Finally, the concentration and crystallization process by evaporation can generate crystalized alkali containing only 0.14‰ arsenic, which can meet the technical requirement for alkali in antimony refining.

为实现砷碱渣中锑、碱的资源化和砷的固化,采用水浸分锑-水热石灰沉砷-浓缩结晶提碱工艺处理砷碱渣。结果表明,在浸出温度90 ℃、浸出液固比3∶1、浸出时间5 h条件下水浸,砷浸出率达到97.96%,锑浸出率仅为0.72%,所得浸出渣含砷量仅为0.09%,实现了锑与砷、碱的有效分离;在钙和砷物质的量比1.43、反应温度170 ℃、反应时间2 h条件下沉砷,砷沉淀率达到99.68%,沉砷后液砷碱质量比仅为1.65∶1 000,砷、碱分离效果优异;利用浓缩结晶法,可获得砷含量0.14‰的结晶碱,满足锑精炼用碱的技术要求。

为实现砷碱渣中锑、碱的资源化和砷的固化,采用水浸分锑-水热石灰沉砷-浓缩结晶提碱工艺处理砷碱渣。结果表明,在浸出温度90 ℃、浸出液固比3∶1、浸出时间5 h条件下水浸,砷浸出率达到97.96%,锑浸出率仅为0.72%,所得浸出渣含砷量仅为0.09%,实现了锑与砷、碱的有效分离;在钙和砷物质的量比1.43、反应温度170 ℃、反应时间2 h条件下沉砷,砷沉淀率达到99.68%,沉砷后液砷碱质量比仅为1.65∶1 000,砷、碱分离效果优异;利用浓缩结晶法,可获得砷含量0.14‰的结晶碱,满足锑精炼用碱的技术要求。

In order to achieve utilization of antimony and alkali in arsenic-alkali slag and solidification of arsenic, a new processing technique, consisting of separation antimony by water leaching, arsenic precipitation by hydrothermal reaction with lime, and alkali extraction by evaporation, was proposed to treat arsenic-alkali slag. Results show that water leaching at 90 ℃ for 5 h with liquid-solid ratio of 3∶1 can result in the leaching rate of arsenic up to 97.96% and the leaching rate of antimony just 0.72%. The obtained leaching residue only contains 0.09% arsenic, presenting effective separation between antimony and arsenic. With calcium and arsenic in a molar ratio of 1.43, hydrothermal reaction at 170 ℃ for 2 h can lead to an arsenic precipitation rate up to 99.68% and the solution after precipitation with arsenic and alkali in a mass ratio of 1.65‰, also presenting a good separation effect. Finally, the concentration and crystallization process by evaporation can generate crystalized alkali containing only 0.14‰ arsenic, which can meet the technical requirement for alkali in antimony refining.
