Aiming at the three wastes problem existing in the traditional hydrometallurgical tungsten smelting process, based on the analysis of the complexation coordination characteristics of oxalic acid and tungstic acid, the selective extraction of tungsten from crude tungstic acid using oxalic acid was studied. To clarify the dissolution reaction kinetics mechanism of tungstic acid in oxalic acid, taking pure tungstic acid as the research object and oxalic acid solution as the leaching agent, the dissolution rules of tungstic acid under different temperatures, oxalic acid concentrations and stirring speeds were investigated. The dissolution kinetics of tungstic acid in oxalic acid solution was studied by the equal leaching rate method. The results show that the apparent activation energy of this reaction is 48.9 kJ/mol. Controlled by the chemical reaction, the reaction order of oxalic acid concentration is 1.103 5.

针对传统湿法钨冶炼工艺存在的三废问题,在分析草酸与钨酸的配合配位特性基础上,研究了用草酸选择性从粗钨酸中提取钨。为探明钨酸在草酸中的溶解反应动力学机制,以钨酸纯物质为研究对象、草酸溶液为浸出剂,探讨了钨酸在不同温度、草酸浓度及搅拌速度下的溶解规律,并采用等浸出率法研究了钨酸在草酸溶液中的溶解动力学。结果表明:该反应的表观活化能为48.9 kJ/mol,受化学反应控制,草酸浓度的反应级数为1.103 5。

针对传统湿法钨冶炼工艺存在的三废问题,在分析草酸与钨酸的配合配位特性基础上,研究了用草酸选择性从粗钨酸中提取钨。为探明钨酸在草酸中的溶解反应动力学机制,以钨酸纯物质为研究对象、草酸溶液为浸出剂,探讨了钨酸在不同温度、草酸浓度及搅拌速度下的溶解规律,并采用等浸出率法研究了钨酸在草酸溶液中的溶解动力学。结果表明:该反应的表观活化能为48.9 kJ/mol,受化学反应控制,草酸浓度的反应级数为1.103 5。

Aiming at the three wastes problem existing in the traditional hydrometallurgical tungsten smelting process, based on the analysis of the complexation coordination characteristics of oxalic acid and tungstic acid, the selective extraction of tungsten from crude tungstic acid using oxalic acid was studied. To clarify the dissolution reaction kinetics mechanism of tungstic acid in oxalic acid, taking pure tungstic acid as the research object and oxalic acid solution as the leaching agent, the dissolution rules of tungstic acid under different temperatures, oxalic acid concentrations and stirring speeds were investigated. The dissolution kinetics of tungstic acid in oxalic acid solution was studied by the equal leaching rate method. The results show that the apparent activation energy of this reaction is 48.9 kJ/mol. Controlled by the chemical reaction, the reaction order of oxalic acid concentration is 1.103 5.
