COAL PROCESSING: At the coal processing plant, coal ore is crushed into smaller pieces and impurities (stones, ash, Sulphur) are removed through washing, sedimentation, and drying. Chemicals are often used. In this image, waste water from Ningdong Industrial Park's waste water treatment plant. The yellowish-green pollution stinks even after “treatment“, and is directly dumped into the local river. 04/02/2014
