Dry triboelectrostatic beneficiation of fly ash

It may be possible to reduce the carbon content efficiently by use of beneficiation technologies. Because > 90% of the fly ash in the USA is handled in the dry state, dry beneficia- tion--or triboelectrostatic separation--has been the recent focus of research at CAER, some of which is discussed in this paper.

DRY MAGNETIC SEPARATION OF MAGNETITE ORES

The relevance of the paper is that dry magnetic separation (DMS) is the main beneficiation method of magnetite ores. The lack of efficient industrial-grade machines and apparatus for separating fine-grained magnetite ores means that DMS is used mainly as a pre-concentration operation for fairly large classes.
