Evaluation of Phosphatic Clay Disposal and Reclamation Methods. Volume 2. Mineralogy of Phosphatic Clays

摘要

Twelve phosphatic clays and three sand tailings from Florida phosphate mining areas were examined by X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and chemical analysis. Quantitative estimates of mineral species were made using sample XRD data and XRD data obtained on reference minerals, and sample mass attenuation coefficients calculated from X-ray fluorescence total chemical data.
