TLDR
In this paper, the mobility of > 30 trace elements from four Spanish coals was investigated using sequential extraction procedures, and the total leachable fractions were obtained by comparing the total trace element content in the bulk coal samples with the extractable content.About:

Leaching behaviour of elements from coal combustion fly ash: An overview
Maria Izquierdo,Xavier Querol +1 more
TL;DR: In this paper, the authors provide an extensive look at the extent to which major and trace elements are leached from coal fly ash and give an insight into the factors underlying the leachability of elements and addresses the causes of the mobility.
Journal ArticleDOI
Status of trace element emission in a coal combustion process: a review
TL;DR: In this paper, the occurrence of trace elements (TEs) in coal and combustion waste are introduced. And the mechanisms of trace element transformation during combustion are illustrated as following: the vaporized metals at high temperature near the combustion flame will subsequently nucleate or condense at a lower temperature downstream.
Journal ArticleDOI
A new approach for the classification of coal fly ashes based on their origin, composition, properties, and behaviour
TL;DR: In this article, a new approach for the classification system of coal fly ashes (FAs) based on their origin, phase-mineral and chemical composition, properties, and behaviour is presented.
Journal ArticleDOI
State-of-the-art applications of fly ash from coal and biomass: A focus on zeolite synthesis processes and issues
TL;DR: In this paper, the authors discuss the key factors affecting zeolite synthesis, primarily from coal fly ash; the drawbacks of each approach are also analysed, and the characterization and potential applications of these materials are analyzed in detail through reference to the numerous studies published on fly ash worldwide over the last number of decades.

Phase-mineral and chemical composition of coal fly ashes as a basis for their multicomponent utilization. 1. Characterization of feed coals and fly ashes☆
Stanislav V. Vassilev,Rosa Menéndez,Diego Alvarez,Mercedes Díaz-Somoano,M. Rosa Martínez-Tarazona +4 more
TL;DR: The phase-mineral and chemical composition of feed coals and their fly ashes (FAs) produced in four large Spanish thermo-electric power stations was characterized as a basis for multicomponent FA utilization as mentioned in this paper.

Sequential extraction procedure for the speciation of particulate trace metals
TL;DR: In this paper, an analytical procedure involving sequential chemicai extractions was developed for the partitioning of particulate trace metals (Cd, Co, Cu, Ni, Pb, Zn, Fe, and Mn) into five fractions: exchangeable, bound to carbonates, binding to Fe-Mn oxides and bound to organic matter.

Trace Elements in Coal
TL;DR: In this article, the origins of trace elements in coal and the mode of occurrence of trace element in coal were investigated. But the results were limited to trace element detection in coal.
Journal ArticleDOI
Trace elements in coal and their behaviour during combustion in a large power station
TL;DR: In this article, the role of anhydrite (CaSO4) in the sorption of trace elements such as As, B, Ge, Se, Pb, Mo, Zn and Tl from flue gas and in the reduction of emissions of potentially toxic elements was investigated.
Journal ArticleDOI
Modes of occurrence of potentially hazardous elements in coal: levels of confidence
TL;DR: The modes of occurrence of potentially hazardous elements in coal will be of significance in any attempt to reduce their mobilization due to coal combustion as mentioned in this paper, and it is anticipated that less than 50% of these elements will be routinely removed by conventional coal cleaning procedures.
Journal ArticleDOI
Trace element behavior in coal-fired power plants
TL;DR: In this article, the authors investigated the relationship between the elements in different process streams and established the collection efficiency of the new generation of high-efficiency cold-side electrostatic precipitators in relation to their collection both of total particulate matter and of each individual element.
