On September 17, the completion acceptance of the 8000t/d Beneficiation Extension Project, designed by ENFI, was conducted in the Dulong Mine of Yunnan Hualian Zinc & Indium Stock Co., Ltd.. Mr. Cao Yuanqing, the Party Secretary and Chairman of the Company expressed his satisfaction with the project construction quality in his speech at the event and showed gratitude to every construction party for their hard work. He also highly praised ENFI designer team for their efforts in optimization of design scheme and construction services, especially in rationally optimizing the design scheme of tailings dam in Dagou of Tongjie by the professional designers in tailings, which reduced embankment quantity by one million cubic meters, saving nearly RMB17 million.

Located in Wenshan Prefecture, Yunnan Province, Yunnan Hualian Zinc & Indium Stock Co., Ltd. is a state-owned holding enterprise engaged in mining, beneficiation and smelting. Its Dulong Mine is rich in mineral resources, including a variety of recyclable metals, among which the reserves of indium, a rare precious metal, rank the first, tin the third in China, and zinc reserves come third in Yunnan province. The 8000t/d concentrator extension project in Dulong Mine is one of key construction projects of 2011 “Three One-Hundred Projects”, and also a major strategic development project of Yunnan Hualian Zinc&Indium Stock Co., Ltd..

恩菲完成了该项目的可行性研究,2008年,完成于2011年基本设计和后来的施工图纸。所述8000吨/ d集中器设有单一的生产系统中,在破碎过程先进SAB的工艺流程,以及组合的分离过程(浮选磁性分离 - 重力分离),该浮选为铜,锌和硫回收,对于铁回收率磁分离和的锡恢复浮选重力分离组合工艺,以这样的方式实现锌,铟,锡,铜,银,铁和硫的综合回收。项目,铜 - 锌 - 锡金属矿集中器通过ENFI设计,其特点是复杂的技术,多种矿物质,是在中国单一的生产系统而言最大的锡金属矿集中器。特别是,在锡石过程的重力分离两表数量和表的布局在中国被开拓,用714个表和三层重叠,以节省空间。设计从所有者获得一致好评和充分体现了创新的恩菲的概念。

该项目设计包括新的8000吨/年选矿厂d,尾矿库的大沟同杰的,新添尾矿库和公共配套设施。它产生六种类型的矿物质,具有复杂的工艺流程,建设有限空间,工程地质条件差,施工难度很大。该项目正式开始于2012年5月,并投产成功于2013年9月10日与所有施工各方共同努力,克服重重困难。在操作后仅3个月达到设计能力。所有的产品,除了锡,满足甚至超过其各自的设计目标。该项目近一年的试运行后,通过了竣工验收。集中器的构造标准是前沿国际和一流全国性。
