优化碱液工艺提升脱氟氯效率

Optimization of Lye Process to Improve Defluorination Efficiency

铅锌联合冶炼过程中,次氧化锌含大量氟氯,系统碱洗脱氟氯效果差,导致大量的氟氯带入锌湿法系统并引发一系列问题。铅锌金属有限公司组织大量技术人员对铅锌联合冶炼系统分析,不断摸索,调试工艺流程、工艺参数、设备能力等,通过工艺优化、技术改造,解决了次氧化锌中氟氯脱除效率低的问题,稳定了锌湿法系统的生产。

In the process of lead zinc combined smelting, the secondary Zinc Oxide contains a large amount of fluorine and chlorine,and the effect of the system alkali elution on fluorine and chlorine is poor, which leads to a large amount of fluorine and chlorine being brought into the zinc wet system and brings a series of problems. The JCC leadzinc Metals Company Limited organized a large number of technical staffs to analyze the lead- zinc smelting system, exploreconstantly, debugging process, process parameters and equipment capacity.Through process optimizationand technical transformation, the problems of which low efficiencyfluorine and chlorine in Zinc Oxide are solved,the production of zinc hydrometallurgy is kept in stability.
