What factory is HTC building in Shifang? It is said that this factory is very harmful to Shifang. What is the specific degree of harm? Please specify. thank you

Sodium cyanide is a highly toxic chemical, which needs to be used in the production of molybdenum ore. At the same time, the multi-chamber roasting furnace for roasting molybdenum ore produces a large number of acidic harmful gases such as sulfur dioxide during processing, which causes great damage to the surrounding environment and soil erosion. Waste residue piles up like a mountain, and it is filled with wind and sand on sunny days. Rainwater washes and silts farmland and rivers on cloudy days, which seriously damages the ecological environment. More seriously, many chemicals, such as caustic soda, kerosene, turpentine and other toxic substances, have been added to the washing water, which has been washed day and night, causing serious pollution of the river. According to consulting relevant experts, at present, there is no way to deal with it in the world, so we can only build dams to stop sewage and let it penetrate underground. In Luoyang, there have been several dam failures of waste molybdenum reservoirs, which have caused serious pollution to the downstream. Mines often directly discharge sewage containing chemical components, causing river water pollution, which in turn harms people and animals. Kerosene, sodium silicate and other harmful substances will seriously affect the health and life safety of county residents.

In the production process, waste water, waste gas and waste residue will be produced. Wastewater contains pollutants such as heavy metal ions and carcinogens. The waste gas mainly includes hydrogen sulfide, sulfur dioxide and other harmful substances. The concentration of these gases is extremely high, and the accumulation of waste residue will lead to irreversible pollution. Waste residue will pollute the downstream rivers under the scouring of rain, and waste residue will release a lot of toxic and harmful gases on sunny days. Seriously destroy the ecological environment. More seriously, many chemicals, such as caustic soda, kerosene, turpentine and other toxic substances, are added to the washing water, which not only causes serious pollution of the river water, but also causes groundwater pollution if the wastewater is intercepted for a long time. The pollution of groundwater downstream can reach 50 kilometers! (Our Guanghan is only over 20 kilometers away from Shifang! ! )

Excessive molybdenum affects the metabolism of copper, calcium and phosphorus. Molybdenum and copper form insoluble copper-molybdenum and cannot be used. At the same time, it interferes with the metabolism of calcium and phosphorus, resulting in bone metabolism disorder, arteriosclerosis, connective tissue degeneration and dermatosis, which makes children grow slowly and suffer from dental caries, emaciation, rickets and rickets. Excessive molybdenum may also hinder the process of energy metabolism in the body, leading to myocardial hypoxia and focal necrosis. It is prone to diseases such as stones, iron deficiency anemia, leukemia, ductal cancer, joint pain and deformity, and kidney injury.

Typical case of related pollution: There are three molybdenum mines in Taishang Village, Shi Mao Town, Zunyi County, Guizhou Province, all in Sipinggou. Up to now, there have been many pollution accidents in molybdenum mine, which directly caused five deaths and caused several other diseases, such as tuberculosis, vitiligo and gout. March 2007 13, 1 person died of poisoning because he went to the mining area at night. On February 2 12, two people were poisoned and fainted because local villagers passed by the slag yard. Later, two people went to the rescue and fainted. When people found out, three of them were poisoned on the spot. Transfer from Guanghan!
