China Shenhua Harwusu Open pit Coal Mine Circular Economy Science

The Halwusu open-pit coal mine is located in the eastern part of Zhungeer Banner (Xuejiawan Town), Ordos City, Inner Mongolia Autonomous Region, belonging to the border area of Shanxi, Shaanxi and Inner Mongolia. The surface boundary is 9.59 kilometers long from east to west and 7.03 kilometers wide from north to south, with an area of 67.17 square kilometers; The recoverable raw coal reserves are 1.73 billion tons, making it one of the key coal mines under the national "Eleventh Five Year Plan". The coal quality of Halwusu open-pit coal mine is medium ash, low sulfur, ultra-low phosphorus, high volatile matter, medium high calorific value, and high ash melting point long flame coal. The open-pit mining process uses a single bucket excavator to track mining.

The experimental flotation column (laboratory flotation column) produced by Jupiter Mining has fine and uniform bubbles, and is easy to operate. The fine particle sized bubbles generated by it have a good recovery effect on fine-grained minerals.

Through detailed technical exchanges, both parties have determined to carry out flotation column technology cooperation (JSYF-60) in the field of coal slurry recovery.
