The assessment of the environmental impact of mining and mineral processing is an important part of the research program of the U.S.D.I. Bureau of Mines. Under the Minerals Environmental Technology program, the Avondale Research Center evaluated the accessory minerals and elements, associated with the mining, beneficiation, and processing of phosphate rock in the central Florida phosphate district. In support of this project, a resinloaded paper (RLP) X-ray fluorescence (XRF) method was developed for determining uranium in these processing and waste materials.
