由湖南省环境保护科学研究院承担的“有色冶炼铜镉渣中有价金属提取技术开发”项目通过专家验收,关系到金属镉回收率高低的关键技术得到突破。该技术主要由株冶集团股份有限公司应用。专家验收结果显示,该项目突破有色冶炼传统,实现了微生物物化联合浸提技术,并独创了铜镉渣资源化处理技术,成功将铜镉渣中镉的浸出率提高到96%,镉回收率提高到90%,精镉纯度达到
The project of “Development of Valuable Metal Extraction Technology for Copper and Cadmium Slag in Non-ferrous Smelting” undertaken by Hunan Academy of Environmental Science and Technology was approved by experts and breakthroughs were made in the key technologies that are related to the level of metal cadmium recovery. The technology mainly by Zhuye Metallurgical Group Co., Ltd. application. The expert acceptance results show that the project has broken through the tradition of non-ferrous smelting, realized the technology of micro-bio-chemical combination leaching, and created the resourceful treatment technology of copper, cadmium slag. The leaching rate of cadmium in copper-cadmium slag was raised to 96% Increased to 90%, refined cadmium purity reached
