On October 9, Yunnan Xiangyun Feilong Recycling Technology Co.
, Ltd.
developed the key technology and complete set of process equipment for zinc secondary resource extraction, the key technology of lead sulfate slag wet smelting and complete set of process equipment, which passed the China Circular Economy Association and the China Environmental Protection Federation.
Evaluation of scientific and technological achievements organized by Beijing
.
Experts believe that zinc extraction technology has reached the international leading level.
The project zinc can recycle sodium chloride, potassium chloride, etc.
The results have realized the recovery and utilization of zinc secondary resources, which has good economic, environmental and social benefits
.
The technology of hydrometallurgical lead smelting is an international initiative, opening up a new way for the hydrometallurgy of lead
.
? Among them, the zinc secondary resource extraction key technology project aims at the advanced treatment process of "two-stage neutralization→combined membrane→crystallization and evaporation" initiated by the enterprise's production wastewater, which can recover valuable metals such as zinc in industrial wastewater and overcome the western smelting enterprises.
The problems faced by the recycling of water resources provide a demonstration for the advanced treatment and recycling of similar wastewater
.
? Lead sulfate slag hydrometallurgy project uses zinc smelting lead sulfate slag as the main raw material, which has changed the traditional pyrometallurgical lead smelting process.
All reaction processes are carried out in solution, and no fuel is used for heating during the production process, and there is no sulfur dioxide or lead fumes.
And flue gas emissions, while reducing energy consumption and processing costs, good environmental protection benefits, low comprehensive energy consumption, and fundamentally solve the lead-containing flue gas pollution
.
?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? The energy consumption of the new process is only 1/4 of that of the traditional process, and the production cost is minimized, and the environmental protection and economic benefits are significant
.
? This evaluation committee is composed of 12 experts in the industry, with Qiu Dingfan, an academician of the Chinese Academy of Engineering, serving as the chairman, and Duan Ning, an academician of the Chinese Academy of Engineering and a researcher at the Chinese Academy of Environmental Sciences, serving as the deputy chairman.
The evaluation committee is chaired by Zhang Yonghong, secretary general of the China Environmental Protection Federation.
