by Nelson, M.S., Hawkins, D.W., and Lassetter, W.L., 2024, A capacity assessment on the recovery of critical and economic minerals from sand used for coastal resilience projects: Virginia Department of Energy, Geology and Mineral Resources Program, Open-file report 2024-16, 76 p. and Appendices A-E.This capacity assessment serves as a comprehensive summary of investigations related to critical commodities (e.g. Ti, Zr, REEs) found in marine heavy mineral sands offshore of Virginia, and their potential for co-extraction during beach sand nourishment operations. Five main tasks were completed: 1) VE convened the 2022 Mid-Atlantic Marine Heavy Mineral Sands forum to evaluate the benefits and drawbacks to heavy mineral sand separation and released the proceedings as an open-file report, 2) VE identified existing regulatory requirements for heavy mineral sand co-extraction during beach sand nourishment operations, 3) VE characterized the geology of occurrences of heavy mineral sands offshore of Virginia, 4) VE developed rapid screening methods for critical commodities within marine sediment using a portable x-ray fluorescence instrument, and 5) VE identified the potential next steps to test the feasibility of extracting heavy mineral sands during beach nourishment. 541p. Online only.
