Coal and Its By-products
This cluster of papers focuses on the geochemistry, utilization, and environmental impact of coal and its byproducts. It covers topics such as trace elements in coal, fly ash characterization, rare earth elements recovery, alumina extraction, phytoremediation of coal ash disposal sites, and the distribution of heavy metals.
Papers listed on taxonomy pages are the top few works per node from the OpenAlex snapshot. That list is not exhaustive and is not an endorsement. The topic map and the journal registry remain separate: there is still no authoritative topic-to-venue or topic-to-organization edge. Search is a lexical lookup, not a claim that a venue publishes a topic.
