The overall REE concentrations proved to be similar, both on a between-run basis for the individual fly ash sources and on a between-plant basis. Variations in fly ash quality will occur in larger-scale operations, so on-going attention to the fly ash quality and the response of the fly ash to beneficiation is necessary.

Lafarge Canada Inc. is proposing to build a facility that will beneficiate landfilled fly ash in Alberta. Fly ash is a fine powder that is a by-product of burning coal in electric generation power plants. This by-product is used extensively in the concrete industry as a replacement for cement in the concrete mixture due to […]
