Part of the rare earth enterprises chaos effluent Ministry of Environmental Protection is developing access standards

95% of the world's rare earth production concentrated in China, the rapid growth of rare earth products yield economic benefits , but also poses a serious environmental pollution . Reporters learned that , as a standardized discharge behavior of rare earth production enterprises , the ministry is currently preparing the "rare earth smelting industry pollution prevention feasible Technical Guide " ( hereinafter referred to as guidelines ) , and public comment.

In recent years , China's rare earth smelting industry has entered a rapid development stage , and become the world 's largest rare earth producer. Statistics show that China's rare earth smelting enterprises up to hundreds of existing and rare earth mineral production from 73,000 tons in 2000 , increased to 129,400 tons in 2009 , nearly doubled , about 95 % of the world .

However , the rapid growth of rare earth products yield economic benefits , but also poses a serious environmental pollution . For example , the presence of ammonia wastewater , wastewater emissions of rare earth fluoride production process . At the same time , will produce fluorine and sulfur oxide emissions. The guidelines for the preparation instructions said, " to all kinds of rare earth metals and alloys calculated annual 30,000 tons , 1,200 tons of rare earth fluoride electrolysis gas emissions each year , some companies still exist problems can not be discharged directly or simple treatment discharge standards . "In addition, the discharge of radioactive waste and secondary pollution problem can not be ignored .

According to the preparation instructions revealed that rare earth mine always associated radioactive thorium , which Baotou rare earth ore processing radioactive waste problem is most prominent. Baotou region produce about 50,000 tons of radioactive waste each year , Gansu Rare Earth flooding produced more than 10,000 tons of slag per year. " Some enterprises in Baotou permanent radiation into the flooding slag slag library stockpiling , some companies will waste water directly into Steel dam, some companies put into the gutters with water flooding into the ground slag and exhaust the Yellow River . Gansu Rare Earth along with the flooding of wastewater discharged into the slag and tailings dam owned , some companies put any radioactive waste storage, without any protective measures for surface water bodies and the surrounding environment , resulting in different levels of radioactive contamination. " preparation instructions wrote.

Environmental Protection Department official said that in recent years , China's rare earth resources to implement more stringent protective mining policies and environmental protection standards, strict industry and environmental access. Including , accelerate the development and refinement of rare earth mining and production standards , the implementation of strict environmental access system, strict implementation of the "rare earth industrial pollutant emission standards ," the development of rare earth industry, environmental risk assessment system.

"Guidelines are currently being prepared to fully draw on the successful experience of developed countries, pollution prevention management system , combined with the actual situation of China's rare earth industry , China's rare earth smelting industry for its pollution prevention guiding role . As long as the strict implementation of the guidelines will ensure that the rare earth producers emissions standards and clean production standards. " the official said .
