摘要
运用高倍数码相机、扫描电镜技术研究酸作用下制粒矿石和原矿石表面形貌演化特征,并从能量改变、孔隙演化和沉淀物生长及调控3方面揭示氧化铜矿表面微观几何形态的浸蚀机理。
High-powered digital camera and SEM technology were used to study the evolution characteristics of surface appearance of granulation ore and raw ore under acid effect.Erosion mechanism of surface microscopic geometry of oxide copper ore was revealed from three aspects, including energy transmutation, porosity evolution and precipitate accumulation and regulation.
