Customer Recognition Fruitful Results

　　FENY's paste backfill technology solves a series of problems caused by traditional mining methods,such as solid waste surface accumulation,environmental pollution,tailing pond leakage,safety accidents such as dam failure,and collapse of the mining goaf,etc..And at the same time,it raises the resource recovery rate from 30%-50%to more than 90%,which greatly extends the service life of the mines.On average,each cubic meter of backfill space,can safely,environmentally friendly treat 1.5 tons of solid waste,0.4 tons of wastewater,resulting in mining solid waste"Go back to where it comes from,"helping mines to achieve"Safe,Environmentally friendly,Low-carbon,Efficient"development.

　　The company's scientifically integrated paste backfill system and key equipment solved the bottleneck problem,and obtained the achievement verification from the Chinese Society of Environmental Sciences,China Environmental Protection Industry Association and Hunan Provincial Science and Technology Department and other relevant departments,with the appraisal of the international advanced level.It won the special top prize of Hubei Provincial Scientific and Technological Progress,the first prize of Xinjiang Uygur Autonomous Region Scientific and Technological Progress,the second prize of Hunan Provincial Scientific and Technological Progress,the special prize of Science and Technology of China Gold Association,the first prize of Technical Progress of China Environmental Protection Industry Association,the first prize of Science and Technology of China Nonferrous Metals Industry Association.And the Technical Requirements for Key Equipment for Backfill of Full Tailings Paste,which was formulated jointly with the University of Science and Technology of Beijing,was awarded the Group Standard Application Demonstration Project of the Ministry of Industry 2022 and many other awards.

　　FENY's paste backfill technology and complete sets of equipment have been applied in more than500 coal,metal and chemical mines under different geological conditions,such as China Shenhua,Lu'an Group,Jizhong Energy Fengfeng Group,Shanxi Coking Coal Group,Kailuan Group,Shaanxi Coal Group,China Gold,Jinchuan Group,Zhongjin Lingnan,Shandong Gold,Zhaoyuan Gold,Zijin Mining,Yunnan Gold,Yunnan Copper Group,Yunxi Group,Western Mining,Western Gold,Xinjiang Nonferrous Metals,China Nonferrous International Mining,China Minmetals,etc..And exported to DR.Congo,Mongolia,Russia,Laos,Kazakhstan and other"Belt and Road"countries along with state own enterprises,which has achieved good economic and social benefits of tailings and gangue treatment,and won the high recognition of the customers.
