Abstract
A scheme has been developed for the separation of compounds in size-fractionated fly ash by linear density gradients. Minor crystalline components such as calcium ferrite, haematite, magnetite, MgO, barite, anhydrite, rutile and mica were identified in addition to the major compounds mullite, quartz and CaO in a fly ash of pulverized subbituminous coal from western USA. The utility of the scheme in identifying minor crystalline components in fly ash has been demonstrated.Keywords
