Mineralogical Characteristics of Phosphate Tailings for Comprehensive Utilization

Figure 1

Phosphate tailings’ mineral structure (TSPL represents transmitted single polarized light, and TCPL represents transmitted crossed polarized light). (a) Colloidal aphanitic collophane (Ap) detritus (TSPL). (b) Fine-grained sand clastic collophane (Ap), quartz (Qtz) (TSLP). (c) Oolitic collophane detritus (TSPL). (d) Dusty substance coated with collophane (Ap) (TSPL). (e) Fine-grained (0.1–0.3 mm) dolomite (Dol) (TSPL). (f) Microcrystalline quartz (Qtz) aggregates (TCPL). (g) Microscopic scaly chlorite (Chl) (TCPL). (h) Allotriomorphic granular plagioclase (PI) (TSPL).
