Pressure nitric acid leaching of alkali-pretreated low-grade limonitic lateriteYong-Lu Zhang,Cheng-Yan Wang,Yong-Qiang Yang,Fei Yin,Bao-Zhong MaInstitute of Metallurgy, Beijing General Research Institute of Mining and Metallurgy摘 要:The pressure nitric acid leaching of alkali-pretreated low-grade limonitic laterite, as well as removing impurity Al(III......
between the silicates and sodium hydroxide in-situ during the alkali dissolution process. Meanwhile, the water-leaching residue of the dissolution products was characterized by X-ray diffractometry...,Mg2+经过碱浸过程可以脱离SiO4阵列,以Mg(OH)2形式从其硅酸盐中得以释放.
