Performance characteristics of heavy media cyclones using fly ash-derived heavy media

Technical Report ·
OSTI ID:6480468
;
The potential for use of the magnetically separated iron-rich fraction of coal fly ash as heavy medium material for float-sink benefication of coal was investigated. Comparative coal beneficiation separations are made using commercial magnetite samples and magnetically separated fly ash samples. Laboratory experimentation is used to characterize the heavy media materials, determine particle durability, measure abrasion and corrosion of construction materials, compare media stabilities and viscosities, and determine flow circuit power requirements.
