Investments increased production capacity and quality
Previously, Hunchun Zijin was a local state-owned enterprise located in Hunchun City, Yanbian, Jilin Province, China. Due to challenges with the company’s operations as well as the declining market prices for copper, the company was faced with major hurdles. Through Zijin Mining Group Co., Ltd.’s acquisition, Hunchun Zijin Mining Co., Ltd. was formally established in December 2002.
According to Gong Dianfa, Vice President of Hunchun Zijin Mine, in order to maintain the stable development of the mine, the management is focused on improving the production capacity and product quality by optimizing their entire process and enhancing their employee’s knowledge.
For these reasons, Hunchun Zijin has invested roughly EUR 142 million (1.1 billion Yuan) in three large-scale reconstruction and expansion projects that have rapidly increased the production capacity from 850t/d to 25,000 t/d, and continuously improved the recovery and utilization of resources. This includes process renovations to all three* production lines in the past 10 years.
*The 4,000 t/d production line in 2004, the 9,500 t/d production line in 2008, and the 1,000 t/d production line in 2014. All three production lines have three stages and one closed circuit, containing primary, secondary and tertiary crushing.
