China will further standardize the behavior of rare earth enterprise pollution

As standardized sewage behavior of rare earth production enterprises , the Ministry of Environmental Protection recently released "rare earth smelting industry pollution prevention feasible Technical Guide " (draft ) , 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: " In 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 problem of secondary pollution emissions and radioactive waste can not be ignored . Guidelines for the preparation instructions , wrote: " The flooding of some enterprises in Baotou radiation slag slag into permanent repository storage, some companies will waste water directly into Steel dam, flooding some companies the residue washed with water into drains into the ground and discharged to 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. "

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 . Qie Jianrong
