Ecological disaster

At 16:00 on July 3, 2010, the staff of the Zijinshan Copper Mine Wet Process Plant found that the sewage water level in the sewage pond dropped abnormally, and some wastewater flowed into the Tingjiang River from the drainage culvert below the sewage pond. According to preliminary judgment, the impermeable membrane cushion of the wastewater pool was abnormally disturbed, resulting in partial damage of the impermeable membrane. The wastewater penetrated into the drainage culvert below the wastewater pool and flowed into the Tingjiang River. According to preliminary statistics, the leakage of wastewater was 9,100 cubic meters.

The announcement of Zijin Mining stated that the main cause of the leakage accident was the continuous heavy rainfall in the previous stage, which caused the groundwater level in the solution pond area to rapidly rise, exceeding the elevation of the bottom of the sewage tank, causing an imbalance in the upper and lower pressures, forming a shear effect, and causing the bottom of the sewage tank to increase. Cracks everywhere, causing leaks in the sink.

After testing, the leakage wastewater is mainly copper-containing acid wastewater, and there is no highly toxic substance. Fujian Province has set up an investigation team to carry out work in the polluted areas, and relevant departments are strengthening water quality monitoring and taking measures to do good aftercare.

On July 15, 2010, Shanghang County, Fujian Province held a press conference to report the results of the investigation and treatment of pollution accidents at Zijin Mining, and hold the administrative and criminal responsibility of those responsible.

On July 15, the Public Security Bureau of Shanghang County filed an investigation into the suspected major pollution accident of sewage leakage pollution of the Zijin Mining Copper Mine Wet Plant in accordance with law, and summoned relevant staff of Zijin Mining according to law. Some responsible persons were controlled, including three detainees "

On July 18, 2010, the Guangdong Provincial Environmental Protection Department issued an express letter to the Fujian Provincial Environmental Protection Department, stating that in recent days, the copper content of the effluent of the Cotton Beach Reservoir in Fujian Province and the water body of Qingxi Hydropower Station in Guangdong Province has increased significantly, which has exceeded the fishery water quality. The standard has a significant impact on the cross-border river sections of the two provinces, leading to greater risks for fishery farming in the river sections of Meizhou. [

Ecological disaster

In the towns of Xiadu and Zhongdu in Shanghang County, a large number of fishermen are fishing around the Cotton Beach Reservoir. With the exception of fishermen in the tributaries of the Tingjiang River or the inner lake, almost all fishermen along the Tingjiang River have experienced unprecedented large-scale fish deaths. For the local mother He Tingjiang, a great ecological disaster has undoubtedly been created.

Fishermen suffer heavy losses

For fishermen, the loss was huge and painful. According to local residents, the largest farmer in Hongshan Town can sell more than 10 million yuan a year. And millions of sales abound. Earlier, Xinhua News Agency reported that only 3.78 million kilograms of dead fish and fish poisoning occurred in the cotton beach reservoir area. However, this data was denied by the local government, claiming that it was only 580,000 jin, which is still less than the fraction reported by Xinhua News Agency. "Do you believe this figure of 580,000 catties? Anyway, we dare not believe it." Fisherman Zhang Aimin said. In order to compensate the masses, the county government purchased all the fish in cages at 6 yuan per catty. Quickly salvage and landfill some dead fish, perform harmless treatment, return the live fish to Tingjiang, and sign an agreement with the farmers. The required funds will be advanced by the government.

Contaminated drinking water sources

At present, the local people are generally concerned about why these waters can cause a large number of fish deaths, but people can drink normally? Fu Weiguo, deputy head of the Shanghang County Epidemic Prevention Station, explained that fish have higher requirements for copper content in the water. When it reaches 0.1 mg / L, the fish will be poisoned or even die. Copper is an essential trace element for the human body. Fu Weiguo said: "Even if the drinking water exceeds 1.0 mg of copper per liter, it will only make the water appear a little bit disgusting and will not cause people to be poisoned." (Actually, excess copper is harmful to the human body. (See copper poisoning entry) Zijin Mining claims that the sewage is non-toxic, and the government says it is not highly toxic. There is obviously a difference between these two statements. In response, Zou Yongming, Minister of Propaganda Department of Zijin Mining, responded that the fact is that the human body is non-toxic for drinking, but the fish is toxic for drinking because the fish has 1000 times the standard for water. However, the claim that "the human body is non-toxic to drink" does not reassure local residents. Yesterday, the reporter found in the local investigation that the local residents almost no longer drink tap water, but bought water to drink on the market.

Slow government response

"After the dead fish happened, many fishermen came to the government to report the situation, but it was not until one week later that the government sent people to inspect it. All the hard-fed fish were dead, and we do nt know why. What has the government done for a long time? "Said fisherman Zhang Aimin. It was not until July 12 that the Shanghang County government officially notified the accident. At this point, a full nine days have passed since the initial dead fish phenomenon occurred.

Late announcement by the company

In addition to questioning the pollution of Zijin Mining, this incident also points to Zijin Mining's slow information disclosure mechanism. The pollution incident occurred on July 3, but Zijin Mining has not made a public announcement about it. It was not disclosed in the evening until it was disclosed by the media yesterday. It is worth noting that since the sewage leak occurred at the Zijinshan Copper Mine on July 3, it has not been announced to investors through public channels for more than a week, and stocks have continued to trade normally. After such a bad environmental accident, the company did not make a normal announcement and suspended trading, which is irresponsible to investors.

Zijin Mining Group Co., Ltd., referred to as Zijin Mining, is an industrial company listed on the Hong Kong Stock Exchange. Its main business is engaged in the exploration, mining, production, smelting and sales of gold and other metals. Its main assets are in Zijinshan, Fujian Province, China. Gold mine is China's largest gold mining enterprise.

Environmental risks of Zijin Mining have already appeared. In May of this year, the Ministry of Environmental Protection of the People's Republic of China reported criticism of 11 listed companies, including Zijin Mining, due to serious environmental protection issues that had not been rectified on schedule, and there were significant environmental risks. Zijin Mining issued an announcement on May 28 in response to relevant rectifications. Less than two months later, Zijin Mining's sewage treatment system had another problem; klkpoop] o] k.

It is understood that this is not the first time that Zijin Mining has encountered similar pollution problems. At the end of May this year, the Ministry of Environmental Protection announced the "Notification Criticizing Companies and Their Environmental Issues That Didn't Complete Rectification on Schedule". Zijin Mining became one of the 11 listed companies being notified. Including the Zijinshan Copper Mine).

The notification from the Ministry of Environmental Protection in May this year showed that the sewage treatment system for the leachate from the Xiatianshan gold (copper) mine in Shanghang County had been suspended from September 2009 without the approval of the environmental protection department. The site inspection was still suspended. Transportation state; after the tailings slag leachate is collected in the collection tank, it is directly discharged into the rear storage without treatment.

In addition, on April 25, 2009, a leakage accident occurred in the backwater system of the Dongping old mine tailings pond in Chongli County, Zhangjiakou, Hebei Province. At the end of the same year, the Longyan Municipal Environmental Protection Bureau of Fujian Province received two complaint letters, pointing to the fact that Zijin Mining polluted the water source in Wuping Xiacun Village.

Zijin Mining's annual report shows that the company's profit in 2009 reached 5 billion yuan. The largest shareholder is Fujian West Xinghang State-owned Assets Investment and Management Co., Ltd., which represents the State-owned Assets Supervision and Administration Commission of Shanghang County, Fujian Province, holding 28.96% of the shares.

Zijin Mining has brought great wealth to the local area. Until the 1990s, Shanghang County's fiscal revenue has been ranked last in the entire Longyan area. Since 2002, with the rapid development of Zijin Mining, Shanghang has become the most economically developed area in the region, second only to Longyan. According to statistics, in 2006, the contribution of Zijin Mining to all taxes in Shanghang reached nearly 70%.

However, the local people have been questioning the environmental protection records of Zijin Mining.

In 1999, the torrent flooded the dam of Zijin Mining to intercept the waste slag, and the slag with the residual liquid of sodium cyanide whistled down, destroying the local farmers' crops, causing fierce conflict between the farmers and the compensation workers of the village of Zijin Mining.

In October 2000, a car carrying 10.7 tons of sodium cyanide from Anhui Shuguang Chemical Co., Ltd. leaked while transporting raw materials to Zijin Mining, causing 102 villagers nearby to be hospitalized for poisoning, massive deaths of livestock and poultry, and drinking water sources. Severe pollution. This incident was confirmed by the local government and the State Environmental Protection Administration as a major environmental pollution and destruction accident.

However, the two accidents caused by Zijin have not been dealt with and punished in any way: the accident in 1999 was identified as a natural disaster without penalty, and the accident in 2000 was identified as the responsibility of Anhui enterprises.

In recent years, Zijin Mining has acquired sub-mines in several provinces and regions, and some sub-mines have also been exposed due to leakage pollution.

In May of this year, the Ministry of Environmental Protection conducted a post-audit of listed companies that passed environmental protection audits in 2007-2008, stating that "the 13 companies and subsidiaries including Zijin Mining Group Co., Ltd. and other companies have different types of environmental protection problems." .

The person in charge of Zijin Company acknowledged to reporters that this incident has shown that the company has not fully fulfilled the responsibilities of a listed company on internal production management and environmental protection due diligence.

So, what price and punishment will Zijin Mining pay for the pollution incident? According to the reporter, Zijin Mining Copper Mine Wet Process Plant has been discontinued and comprehensive rectification will be carried out. At the same time, it will bear the responsibility for the accident and the economy in accordance with the conclusion of the accident investigation. Compensation.
