[Perspective Club · Ecological Supervision] Judging!"Washing holes" in the abandoned mine, Miyun Court: imprisonment+fine

A few days ago, the People's Procuratorate of Beijing Miyun District appeared in court to support public prosecution against Xia Moumou, Wang and others suspected of pollution.

Gold: Soak with chemical agents, wash the rock wall and bottom of rocks at the bottom of the mine

The defendants Xia Moumou and Wang Mou and others were in the abandoned mine in the Longyao Panel area of ​​Fengjiayu Town, Miyun District, Miyun, in July to August 2020. Use solutions with gold -selected minerals, sodium hydroxide and other substances to spray in the rock wall and bottom crushed gravel for gold selection. No protective measures and wastewater and waste residue collection and disposal procedures were taken in the operation, resulting in the direct discharge of wastewater in the washing ore into the cracks of the mountain and the soil at the bottom of the mine. Sample testing, the cyanide containing cyanide in the washing of the mine was a hazardous waste, and the concentration range of the total cyanide of the wastewater-shaped type was distributed at 51.6-218mg/L. The limits of cyanide are 0.2 mg/L emission standards.

The Miyun Court believes that the defendants Xia and Wang ignored national laws and discharged toxic substances when illegally carried out funds and severely polluted the environment. His behavior had constituted the crime of pollution and should be punished according to law. The defendant Xia Moumou had a plot of criminals and should be punished by heavy punishment according to law. After the defendant Wang arrived at the case, the crime was truthfully confeired, and he could be punished lightly according to law. The defendants, Xia Moumou and Wang, pleaded guilty and could deal with them in accordance with the law.

In the court, both defendants were sincere and confession and confession.

Trial site

The People's Court of Miyun District was sentenced to court, and the defendant Xia Moumou committed the environmental crime of polluting the environment in accordance with the law, sentenced to one year and five months in prison, and fined 20,000 yuan. Month and fined 10,000 yuan.

How much harm is to collect gold with chemicals?

This stolen behavior is also called "washing hole". Li Zhenyu, a Beijing mining lawyer, said that the so -called "washing hole" is to use cyanide to turn gold into a water -soluble compound in the abandoned gold mines, and then use activated charcoal to absorb the gold in the solution. Get gold sand.

The toxic grading of sodium cyanide used in the "washing hole" belongs to the "extreme harm" and is a hazardous chemical product that must be used to poisoning the poisoning of "toxic substances".

Peng Yingdeng, a doctor of environmental geography at Beijing Normal University, said that "Although sodium cyanide is less toxic than potassium cyanide, once it encounters water, hydrolysis produces highly toxic cyanide (HCN) gas, which is even greater than sodium cyanide."

Related studies have shown that if the concentration of hydrocyanate in the air exceeds 0.3 mg/liter, breathing will cause death.

Li Zhenyu said that in addition, the location of "washing" is mostly abandoned mines that are unmanned. Many reasons have led to the high risk coefficient of "washing" behavior, which can easily cause casualties. The outflow of wastewater containing cyanide in the production process will pollute the ecological environment outside the cave.

Seven departments: special rectification of "washing holes" stealing gold mining behavior

In order to prevent the occurrence of "washing" gold mines, on March 28, seven departments including the Ministry of Natural Resources, the Ministry of Ecology and Environment, and the Ministry of Public Security jointly formulated the work plan for the special rectification action of "cracking down on the" washing "gold mining mining mining mining mining mining mining mining mining mining mining mining mining mining mining mining mining mining mining mines "

It is understood that as of June 15, 29 provinces with gold mining activities across the country have formulated and issued a special rectification operation for implementation plans. The special rectification operation of the gold mine is being fully launched across the country.
