招远市中矿绿色智能贵金属新材料一体化项目：全球独有的“无害化-产品化-高值化”全产业链利用模式

　　Zhongkuang Green Intelligent Precious Metal and New Material Integration Project in Zhaoyuan : the World's Unique "Harmless, Poductization, High-Value" Utilization Mode of the Whole Industry Chain

　　中矿绿色智能贵金属新材料一体化项目，是山东省优选项目，由全国黄金行业前十强中矿集团斥资45.6亿元建设，规划占地483亩，聚焦打造全行业领先的智能生态冶炼新样板，主要建设三大功能区，目前供料区土建工程已完工；生产区8台浓密机和相关土建工程已完成，智能提取初选一车间完成主体框架，智能生产二车间、绿色循环利用车间砌体工程完成90%；试验、研发车间等辅助区正在进行基础施工，2024年将建成集智能化、集约化、清洁化为一体的多金属冶炼和新材料生产基地。

　　Zhongkuang Green Intelligent Precious Metal and New Material Integration Project, is a premier project in Shandong Province, built by Zhongkuang Group, a top ten enterprise of China’s gold industry with an investment of 4.56 billion yuan and a planning area of 483 acres. The project focuses on building an industry-leading new demonstrating model for intelligent ecological smelting, with the three main functional areas. The the construction of supply section has been completed; 8 thickeners and related construction in the production section have been finished. The main structure of the intelligent extraction primary workshop has been completed, and 90% of the masonry works of the intelligent production workshop and the green recycling workshop have been completed. Basic construction is in progress in auxiliary areas such as test and R&D workshops. A multi-metal smelting and new material production base taht integrates intelligence, intensification and cleanliness will be built in 2024.

　　项目针对业内企业普遍面临的易处理金精矿“吃不饱”、复杂金精矿“吃不下”的双重窘境，采用中矿集团研发的金精矿双循环熔炼提金新技术，并按照国际一流智慧工厂标准，引进全球领先的工程技术公司美卓集团1000多台套高端智能装备，高标准建设“三废”处理系统和尾渣综合回收利用系统，在有效破解复杂金精矿难处置问题的同时，将复杂金精矿回收率提升13个百分点，实现金、银、铜、铅、锌、铂、钯等多元素综合回收，真正做到工艺用水循环利用、废气达标排放、尾矿“吃干榨净”。

　　Having not enough easily manageable orders and being unable to fully handle complicated mines are common issues within the industry. In view of the double dilemma faced by many enterprises, the project adopts the new technology of double cycle smelting and gold extraction of gold concentrate developed by Zhongkuang Group, and introduces more than 1,000 sets of high-end intelligent equipment from Metso Group, the world's leading engineering technology company, in accordance with the international first-class smart factory standards. With high standard construction of "three wastes" treatment system and comprehensive tailings recovery and utilization system, the project effectively solves the problem of difficult disposal of complex gold concentrate, increasing recovery rate of complex gold concentrate by 13%. This achieves comprehensive recovery of gold, silver, copper, lead, zinc, platinum, palladium and many other elements, and truly realizes the recycling of process water, up-to-standard discharge of exhaust gas and complete use of tailings.

　　项目建成投产后，企业产能将在现有基础上翻两番、达到100万吨，年精炼成品金60吨，成品银75吨，成品铜、铅等其它元素1720吨，年可实现销售收入125亿元、利润10.6亿元，年可减少氰化尾渣15万吨，资源化利用砷2万吨，构建起全球独有的“无害化-产品化-高值化”全产业链利用模式，为烟台绿色低碳高质量发展贡献智慧和力量。

　　After the project is completed and put into operation, the designed capacity of the enterprise will quadruple on the existing basis to 1 million tons, annually producing 60 tons of refined gold, 75 tons of finished silver, 1,720 tons of finished copper, lead and other elements. The annual sales revenue can achieve 12.5 billion yuan with a profit of 1.06 billion yuan, while reducing 150,000-ton cyanide tailings and utilizing 20,000-ton arsenic per year. The project shall build the world's unique "harmless, productization, high-value" utilization mode of whole industry chain, contributing wisdom and strength to Yantai's green, low-carbon and high-quality development.
