(Summary description)The "China's first 450t / D refractory gold pressure pre oxidation chemical plant" developed by Zijin Mining and Metallurgy Design and Research Institute / Xiamen Zijin Mining and Metallurgy Technology Co., Ltd. and participated in the design, construction and commissioning in the whole process achieved the production capacity and standard after 3 weeks of belt commissioning in Guizhou Shuiyindong gold mine at the end of 2016. The annual output value of the project is 500-600 million yuan. Compared with the original process, the comprehensive metal recovery rate of the mine will be increased by at least 30%. At the same time, about 50 tons of gold resources that could not be used in the mining area can be developed and utilized, and the new economic value is about 10 billion yuan. The construction of the project will be completed in 14 months, the cold and hot water linkage test run will be completed in 3 months, and the project will be completed in 3 weeks

  由紫金矿冶设计研究院/厦门紫金矿冶技术有限公司开发并全程参与设计、建设、调试的“中国首个450t/d难选冶黄金加压预氧化工厂”于2016年年底在贵州水银洞金矿带料调试3周后实现了达产达标。该项目年产值5-6亿,与原有工艺对比,至少提高所属矿山金属综合回收率30%,同时可开发利用矿区原来不能利用的约50t金资源,新增经济价值约100亿元人民币。项目14个月完成建设、3个月完成冷、热水联动试车、3周达产达标。2017年1月,在投产仪式上,中国工程院院士邱定蕃、何季麟、邱冠周等专家学者对该项目给予了高度评价,一致认为该项目填补了我国难处理金矿加压预氧化的空白,达到“国际领先”水平。
