Symposium Rare Metal Extraction & Processing
Presentation Title Rare Earth Elements Extraction from Coal Waste Using Biooxidation Approach
Author(s) Prashant K. Sarswat, Michael Free
On-Site Speaker (Planned) Prashant K. Sarswat
Abstract Scope The rare earth elements (REEs)are exceptionally helpful in applications, for example, gas sensors, hybrid vehicles, metal alloys, semiconductors, fluorescent and LED lights, electrical equipment, and related magnets. REEs and related reserve in coal-related materials are huge. Under an assumption of typical production of coal ~ of 600 million short tons for each year with a normal REE ~ 200 ppm, the potential annual reserve is 120,000 tons. The majority of those REEs are found in ash or gangue derived or associated from coal-related materials. Under typical coal plant activity, the REEs frequently end up in reject heaps or tailings impoundments. By and large, variety of REEs can be extracted with ease utilizing suitable coal processing steps. In the current exploration, the preparing approach utilizes a characteristic pyrite stream, which was collected during coal cleaning and used to improve recovery. Biooxidation step was applied to coal-based materials for REE recovery.
