News November 4, 2019 - Chinese state-owned nonferrous metals producer Zijin Mining said today that it has agreed to buy the Timok copper and gold mine in Serbia from US-based Freeport McMoran. Zijin expects the acquisition to be completed before 29 February 2020, subject to the approval of the Chinese and Serbian governments and authorities. This acquisition is part of Zijin's strategy to secure mining assets and expand globally. Zijin will pay an initial $240mn to Freeport to acquire its stake and mining rights under Timok Copper and Gold mines. Five exploration rights at the periphery of the mine will also be part of the acquisition. Once production at the mine begins, Zijin will pay a further 0.4pc of the net smelting proceeds to Freeport, but the total amount will be capped at $150mn. At present, the upper and lower belts of the mine belong to two development entities and the acquisition will resolve the development constraint between the two zones.Nevsun Resources owns the upper belt of the Timok mine. The firm was acquired by Zijin on 12 March this year. Zijin also acquired a 63pc stake in Serbian copper miner and smelter RTB Bor in September last year. If the acquisition closes, Zijin will have full ownership of the upper and lower belts of the Timok mine. The lower belt of Timok mine is a low-sulphur porphyry gold-copper ore with simple composition and few impurities. The ore could be used for blending in concentrate feedstock to reduce harmful impurities. Due to deteriorating copper ore grade globally, levels of arsenic, lead, fluorine, cadmium and mercury level have been rising in copper concentrates. As a result, many Chinese smelters required copper concentrates to be blended prior to smelting. Many copper concentrate cargoes that did not meet China's standard on the level of arsenic, lead, fluorine, cadmium and mercury level have also been rejected from the country.Zijin produced 434,501t of refined copper and 183,131t of zinc last year. Output this year is expected to increase, driven by the group's overseas operations

- ZIJIN Mining Group Co said it has suspended the production of a copper smelting plant in southeastern Fujian Province after a gas poisoning accident killed three workers during the Spring Festival holiday.  A repair worker fainted after entering a clogged tank in the plant and three other workers also collapsed as they tried to rescue their colleague, Zijin Mining said in a filing to the Hong Kong Stock Exchange today.  It said three workers died of gas poisoning and one was saved and is now in stable condition. An investigation is under way in the 200,000-ton-a-year copper smelting plant that was in trial operation.  The shares of Zijin, China's leading gold and copper producer, fell almost 7 percent in morning trade in Hong Kong.

February 1, 2012 - Three workers were killed by poisonous gas as they were repairing a clogged chemical tank in a copper smelting plant in the coastal Fujian Province, Beijing Times reported today.  The three victims were employees of the Zijin Copper Corporation, a subsidiary of the publicly listed Zijin Mining Group Co. Zijin said the accident occurred on Thursday afternoon when a chemical tank in the plant became clogged.  One worker entered the tank to remove the blockage but suddenly passed out. His three co-workers tried to rescue him but also lost consciousness.  The four were rushed to a hospital immediately but three of them were pronounced dead. One was out of danger after emergency treatment, the report said.  Zijin Copper Corporation has suspended production in the plant while an investigation is under way, the company said.

Outotec has made an agreement with Shanghang County Jinshan Trading Co. Ltd. on the supply of smelter technology and services. The end user will be Zijin Copper Co. Ltd. The contract value is approximately 7 million euros.  The agreement covers Outotec® Flash Smelting license, the supply of proprietary process equipment and services for Zijin's copper smelter project in Shanghang, Fujian Province, China.  The greenfield smelter is planned to produce an annual 200 000 tonnes of cathode copper. Outotec's material deliveries are scheduled to take place in the third quarter of 2010.   Outotec® Flash Smelting technology is the cleanest smelting method available for copper and nickel. Zijin will be the fifth smelter in China using the technology because of its low energy consumption and superior environmental performance.

March 13, 2009 - On 11 March, a ceremony for the founding of Zijin Copper Industry Co. Ltd. and a 200000t copper smelting project being put into operation was held at Jiaoyang village. This marks that a 200000t copper smelting project undertaken by Zijin Copper Industry Co. Ltd. has started to make a historic step.A capacity of 200000t copper smelting project in one stage construction will be 200000t electrolytic copper per year, and by-products will be about 5t gold and 700000t sulphuric acid annually. This project has a unique regional advantage. Relying on Zijinshan gold-copper mine and oversea copper resources, it is a large-sized copper smelter nearest to harbor in China.This project conforms to China national industrial policy. It is one of main construction projects in Fujian province in 2009, and the largest investment project in Longyan city since the founding of new China also. In addition, this project is characterized by large investment, high technology and better industrial driving force. It not only lays foundation for speeding development and becoming top of Zijin Mining Group, but also has a great importance to and plays a positive role in improving Shanghang county economy, and promoting economic structural adjustment, industrial optimization and upgrading, changeover of development modes, and economic development to be good and fast in Shanghang county and Longyan city.
