Abstract:

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.

Key words: oxygen-enriched bottom-blown catch made matte process, environment-friendly agent, cyanide pollution, environmental protection metallurgy, standardized index system
