锌焙砂硫酸浸出渣中分离 ZnFe2 O4的研究
Research of Separating ZnFe2 O4 from Zinc Calcine Sulfuric Acid Leaching Residue
摘要
Abstract
Taking zinc calcine as raw materials , water washing with high temperature and magnetic stirring were carried out after solid-liquid separation at constant temperature following sulfuric acid leaching.The leaching product was used for solid phase oxidation roasting after filtration , drying, screening and adding additive .The screening product of rough purification was roasted after adding additive and mechanical activation by high energy ball milling .The fine purification product was further studied by laser particle size analysis , XRD and EDS analysis .The results showed that zinc ferrite content was high to 98%, and it mainly concentrated into 0.240 ~3.802 μm, 3.802 ~17.378 μm and 17.378 ~138.038 μm size fractions, of which the proportions were 41.83%, 36 .70%and 21 .47%, respectively .The smaller the particle size was , the larger the particle size distribution would be .Thus, the content of -20μm particle size was 80%.At present , the prod-uct with a certain powder properties could be processed into high performance zinc ferrite materials by further refinement and homogenization treatment .关键词
