II. Basic information on investment projects
1. Project name: green upgrading Project of Zinc smelting Slag in Danxia smelter
2. Construction site: Danxia smelter, Dongtang Town, Renhua County
3. Construction scale:
The main results are as follows: (1) Slag treatment production line: the amount of slag treated is 283 000 tons / year, of which the waste residue produced by Dan smelting zinc system is 127 000 tons / year, the waste residue produced by Shaoguan smelter is 56000 tons / year, and the social solid waste containing lead in Guangdong Province is 10 000 tons / year. The lead concentrate produced by Fankou Mine is 931 000 tons per year as trapping agent.
(2) cadmium and cobalt recovery production line: treatment of 4000 tons / year of purification slag produced by the existing system of Danye smelter.
4. Product scale: annual output of lead ingots 116100 tons, silver ingots 120.42 tons, cadmium ingots 413.11 tons, secondary zinc oxide 41600 tons, lead-antimony alloy 157.99 tons, cobalt concentrate 39.93 tons, crude copper 992.19 tons, sulfuric acid 186300 tons, crude Hg 61.9 tons.
5. Treatment process: the zinc slag treatment project of Danxia smelter plans to adopt oxygen-rich flash smelting technology to realize the on-site harmless and resource disposal of zinc smelting slag, and to assist the government to solve the problem of transregional transfer of hazardous solid waste.
III. The impact of investment projects on the company
1. The project with advantages in resource utilization, regional risk control and enterprise technical and economic indicators has comparative advantages in the comprehensive utilization of resources, centralized pollution prevention and control and technical and economic indicators in the east of Danxia smelter site, which is conducive to the realization of mining-selection-metallurgy integration and lead-zinc combined smelting clean production mode, is conducive to the realization of resource cycle and energy saving and emission reduction, and avoid new pollution points. It is beneficial to the centralized control of regional environmental risk.
2. The project to significantly enhance the green smelting and environmental protection level of Danxia smelter plans to adopt oxygen-enriched flash smelting and oxygen pressure leaching wet zinc smelting process, which can give full play to the advantages of lead-zinc combined smelting enterprises, replenish the slag of lead and zinc system as raw materials to form a complete production system, so as to effectively solve the problems of comprehensive recovery and waste slag treatment in Danxia smelter, and realize on-the-spot transformation and harmless disposal of resources. We will improve the level of comprehensive utilization of enterprise resources and the level of environmental protection in green smelting.
