he mechanical chemical activation method has shown promise tool for pretreatment in the recovering of rare earth metal from
wastes because it triggers physicochemical changes from particle comminution, new surface generation, crystalline structure
defects and polymorphic transformations. In this paper, a new pretreatment method was employed for the enhancement of
phosphate mineral comminution by planetary ball mill in the atmosphere environment for mechanical activation. The mechanical
activation was carried out by milling of phosphate concentrate for 20, 60 and 90 min. The analysis of X ray diffraction (XRD)
patterns of mechanically activated phosphate concentrate indicated that no phase transformation occurred during milling
operation. In addition, the microstructural changes to nano size particles of mechanically activated phosphate concentrate were
completely obvious from broadening of XRD peaks. The XRD peaks indicated that most minerals changed to amorphous which
basically modified their properties for further enrichment.
