【摘要】 在阳极泥湿法处理流程中，草酸由于还原选择性好，速度快，而被许多生产厂家用作从氯化分金液中还原金。但由于现行冶炼矿源多、杂，从而造成分金液成分的波动，致使其金粉质量难以控制。本文从理论上探讨草酸沉金过程中杂质元素银、铜、铅的行为。更多还原

【Abstract】 In the hydrometallurgical process of anode slime,usually oxalic acid is used as reducing agent to precipitate gold from chlorination solution owing to its good selectivity and quick reduction.However the composition of the chlorination solution fluctuate due to the complexity of raw material,resulting in poor control of gold powder quality.In this paper the behavior of impurities in the chlorination solution,such as copper,silver and lead, is analyzed thermodynamically.更多还原
