According to the “Investigation on the Impact of Luming Molybdenum Mine’s Emergency Flood Discharge on Water Quality of Water Sources” issued by the Tieli Government Network on July 22, 2018, Tieli City Environmental Protection Bureau, Luming Molybdenum Mine is located in Heilongjiang Province Luming Forest Farm of Tieli Forestry Bureau of Yichun City. The mine started construction in June 2011, put into production at the end of June 2014, and received acceptance in December 2015.

The announcement stated that on July 19, 2018, when the inspection team of the Ministry of Emergency Response conducted a safety inspection of the Luming Molybdenum Mine, the experts of the inspection team raised the issue of potential safety hazards in the tailings inventory. , There is a danger of flooding the dam leading to dam failure, and immediate flood discharge is needed to ensure the safety of the tailings reservoir dam. Luming Molybdenum Mine conducted emergency flood discharge in accordance with the requirements of the inspection team.

On July 20 and 21, the Yichun Municipal Environmental Protection Bureau and Tieli Municipal Environmental Protection Bureau took water samples from the downstream of Luming Molybdenum Mine and the upstream of the water source, and sent them to a third-party monitoring agency and Yichun City Environmental Monitoring station. The test results showed that none of the mine-specific indicators such as lead and chromium were detected. Affected by various reasons such as floods, some indicators such as total nitrogen and chemical oxygen demand are slightly higher than the standard limit. Based on the existing water quality test results and the assessment of the Luming Molybdenum Mine's environmental assessment conclusions, the water source of Yijimi River can be taken normally.

Tieli City Environmental Protection Bureau stated at that time that Tieli City would strictly monitor the water quality of Yijimi River and feed back the test results to Duoyuan Water Company in time, and adjust the production process based on the test results to ensure the safety of urban water supply. At the same time, Luming Molybdenum Mine is required to immediately stop flood discharge after eliminating the hidden dangers of tailings pond safety.

Qixinbao information shows that Yichun Luming Mining Co., Ltd. was established in August 2006 with a registered capital of 20 million yuan, which belongs to the mining and dressing industry of non-ferrous metals. The business scope includes molybdenum mining and beneficiation; mineral product distribution; import and export of molybdenum products. The sponsors of the company are China Railway Resources Group Co., Ltd. and the Fifth Geological Survey Institute of Heilongjiang Province. On August 18 and 23, 2018, he was punished twice by Yichun City Work Safety Supervision Administration.

Molybdenum is a metal element that was discovered relatively late. It was only extracted from molybdenite by Swedish chemists in 1792. Because metallic molybdenum has the advantages of high strength, high melting point, corrosion resistance, and wear resistance, it has been widely used in industry.

my country stipulates that the maximum allowable concentration of molybdenum in ground water is 0.5 mg/L, the maximum allowable concentration of soluble molybdenum in the air of the workshop is 4 mg/m3, and the maximum allowable concentration of insoluble molybdenum is 6 mg/m3.

Molybdenum is irritating to eyes and skin. Part of the contacts developed pneumoconiosis disease, consciously dyspnea, general fatigue, dizziness, chest pain, cough, etc. First aid measures include: skin contact, rinse thoroughly with soap and water, and seek medical attention; contact with eyes, open eyelids, rinse with running water for 15 minutes, seek medical attention; inhalation, leave the scene to fresh air, seek medical attention; Drink appropriate amount of warm water, induce vomiting, and seek medical attention.
