机械活化后变质型磷矿粉表面形貌及矿物成分变化研究
The research of Surface Morphology and Mineral Composition Change to Metamorphic Ore after Mechanical Activation
摘要
Abstract
Applying:Scanning electron microscopy (SEM)and its affiliated energy dispersive spectrometer (EDS)in laboratory experiment,This thesis revealed the surface form structure and mineral composition change of me-chanical activated metamorphic ore.The main findings are listed as follows:The particle structure of metamor-phic ore was compact,appearance of microcrystalline apatite flakes and crystalline before mechanical activa-tion,while loose structure,particles finely ,flocculent and crystal boundary surface vanished after mechanical activation.Elements of six points (a1 ,a2,a3,A1 、A2 and A3)of metamorphic ore before and after mechani-cal activation were the same (both containing at least O,Ca,C,Si,P,Fe,Al,K and Mg),but the contents were much differently.P and Ca element peak values of a3 point before mechanical activation were much more higher,but the other two levels were low.Ca and P element weight percentages of three points(A1 、A2 and A3))after mechanical activation increased by 1 9.97% and 7.71 %.The Ca /P average ratio increased by 23.26%.关键词
