Dense Media Separation (DMS) Plants - JXSC Machine

The upper limit of the ore particle size is related to the ore size, embedding characteristics and equipment size. In usually, the ore is 50-150mm, and the coal is 300-500mm. DMS can greatly reduce the surrounding rock and waste rock under the same processing capacity, reduce ore grinding consumption, thus reduce production costs.

Beneficiation of an Indian non-coking coal by column ...

Beneficiation of non-coking coal is gaining ground in India. It not only reduces the volume of inert content to be transported to the power plant and also lowers the wear in the boiler houses. For special applications such as the fuel for integrated gasification combined cycle plant (IGCC), the ash content in the coal should preferably be below 15 %. Indian coals are characterized by high ...
