摘　　要： 目前,我国采用"富氧底吹造锍捕金"和"碱性环保药剂替代剧毒氰化钠"两大新技术逐步解决黄金工业可持续发展与环境保护之间的矛盾。前者从根本上解决了氰化物污染、金矿资源综合利用及金属回收率低等问题,是我国处理低品位、复杂多金属矿石的首选技术。后者虽能从源头上解决氰化物污染问题,但不能处理复杂矿物,且存在药剂消耗量大及溶金机理不明等问题,金属回收率也不及富氧底吹造锍捕金技术。实际应用中应采用富氧底吹造锍捕金炼铜技术处理复杂铜金混合矿,阳极泥中金银的回收采用环保药剂处理,真正实现黄金的环保冶炼。两大新技术要走出国门,还需要在理论、技术指标和设备等方面做进一步的完善和提升,形成完整的技术与装备的标准化指标体系。 At present,two new technologies of oxygen-enriched bottom-blown catch gold made matte process and environment-friendly agent instead of sodium cyanide with highly toxic are used to gradually solve the contradiction between sustainable development in gold industry and environmental protection in China.The former fundamentally solves problems of cyanide pollution,comprehensive utilization of gold resources and the lower recovery rate of metals.It is the first choice for dealing with low-grade and complex polymetallic ores in China.The latter solves the cyanide pollution problem from the source,but there are some fundamental theory problems to be resolved,such as agent consumption is bigger,and the leaching gold mechanism is not clear,metal recovery rates is also less than that of oxygen-enriched bottom-blown catch made matte process.In practice,technology of oxygen-enriched bottom-blown is used to treat the copper-gold mixed ore,the recovery of gold and silver in anode slime should be treated by environmental agent,green metallurgy is really realized.If new technologies are going out of the country and they need to be further improved in terms of theory,technical indicators and equipment to form a complete standardized index system of technology and equipment.
