Manganese Smelting Plant Fire
Ej Atlas
The Wugang Manganese Smelting Plant was completed and put into operation in May 2008. No environmental assessment procedures were carried out. What is puzzling is that this polluting factory, which has no signboards, was able to start production normally. Within a few hundred meters of this factory, there are Wenping Town Middle School, Central ...
