To Tighten Pollution Standards and Introduce National Standards


The Chinese Government is taking measures to tighten pollution standards for rare earth mining in the Inner Mongolia autonomous region. It’s said that the draft regulation had been filed with the Ministry of Industry and Information Technology, which is canvassing opinion within the industry on the proposals, reports China Daily.


According to experts, the permissible amount of the pollutant ammonia nitrogen per liter of production wastewater will be lowered from 25mg to 15mg. China's decision to stop issuing rare earth mining licenses in 2006 led to the closure of many small mines. In September 2010 the government announced draft guidelines aimed at bringing down the number of rare earth firms from 90 to 20 by 2015, which encouraged mergers and acquisitions in the sector.

On the other hand, the Chinese government starts to introduce national standard for the mining industry. China's state administration of work safety is planning to introduce national standards for safety technologies used in the country's coal mines. The four standards will relate to the prevention of coal mine accidents, such as methane gas blasts, underground floods and shaft collapses, by using high-technology polymeric materials.

Polymeric materials are a group of chemical compounds that are used for functions related to the prevention of mine floods, shaft collapses and fire accidents, reports China Daily. At the end of 2010, there were 30 producers of polymeric materials, but a lack of national manufacturing standards has raised concerns among the industry.
