本文简述了国内外硫脲溶金的研究概况,着重对碱性介质中硫脲溶金作了一些探讨。在硫脲溶液中,加入氧化剂过氧化钠,在pH值等于13的条件下,鼓入氧气进行一系列溶金试验:硫脲浓度、氧化剂浓度、温度和鼓氧时间等的变化对溶金的影响。通过上述试验,对在碱性介质中硫脲溶金取得了一定的进展,尤其对含金废料中金的再生具有一些优点,唯目前存在溶金速度慢和硫脲耗量大等问题,有待于进一步研究。 In this paper, the research status of thiourea dissolution in domestic and abroad is briefly reviewed. Some studies on thiourea dissolution in alkaline medium are given. In the thiourea solution, adding oxidant sodium peroxide, under the condition of pH equal to 13, bubbling oxygen for a series of gold dissolution experiments: the change of thiourea concentration, oxidant concentration, temperature, influences. Through the above tests, some progress has been made in the dissolution of thiourea in alkaline medium, especially for the regeneration of gold in waste containing gold, except for the problems of slow dissolution of gold and large consumption of thiourea and so on. For further study.
