Miner innovating for competitive edge

ChinaCoal Pingshuo Group Co Ltd, one of China's top coal producers, is using new technologies to advance its coal-to-nitramine conversion procedures, in line with the rising trend of environmentally friendly industrial production.

The new technologies include procedures like pressurized liquefaction, cooling, and low-temperature methanol washing. Coal that is less suitable for power generation will be converted to porous nitramine particles, which are now a major by-product produced by the group.

Every metric ton of coal, that is less suited for power generation and valued at 230 yuan ($34), can be converted into by-products valued at 840 yuan. And their output now is nearly four times of that in the past, said Hu Wanlin, a Chinacoal executive.
