Abstract

This study achieved a selective separation through evaluating the role of the network structure of illite in apatite flotation, when flotation performance could not be manipulated through mainly modifying the pulp rheology. The presence of a complex depressant, acidified sodium silicate (ASS), changed both apatite rheology and illite rheology slightly, while apatite and illite settled differently. Focused beam reflectometry (FBRM) indicated that the size of illite network structure was largest at 100 g/t ASS. Combining the rheology, settling tests and FBRM measurements suggested a potential ASS dosage for flotation separation of apatite from illite, which was in accordance with the flotation results. Cryo-SEM observation further verified that face-to-face (F-F) aggregated and edge-to-face (E-F) flocculated association of illite was the ideal mode for selective separation between apatite and illite. The results in this study justified that the network structure of clay minerals has a more direct relationship with the flotation performance.

伊利石网络结构在磷灰石浮选中的作用

本研究通过评估伊利石网络结构在磷灰石浮选中的作用，在无法主要通过改变矿浆流变来操纵浮选性能的情况下，实现了选择性分离。复合抑制剂--酸化硅酸钠（ASS）的存在使磷灰石流变学和伊利石流变学都发生了轻微变化，而磷灰石和伊利石的沉降则有所不同。聚焦光束反射仪（FBRM）表明，在 100 g/t ASS 条件下，伊利石网络结构的尺寸最大。结合流变学、沉降试验和 FBRM 测量结果，可以得出从伊利石中浮选分离磷灰石的潜在 ASS 剂量，这与浮选结果相符。冷冻-扫描电镜观察进一步验证了伊利石的面-面（F-F）聚集和边-面（E-F）絮凝联合是磷灰石和伊利石选择性分离的理想模式。该研究结果证明，粘土矿物的网络结构与浮选性能有更直接的关系。

期刊介绍： Applied Clay Science aims to be an international journal attracting high quality scientific papers on clays and clay minerals, including research papers, reviews, and technical notes. The journal covers typical subjects of Fundamental and Applied Clay Science such as: • Synthesis and purification • Structural, crystallographic and mineralogical properties of clays and clay minerals • Thermal properties of clays and clay minerals • Physico-chemical properties including i) surface and interface properties; ii) thermodynamic properties; iii) mechanical properties • Interaction with water, with polar and apolar molecules • Colloidal properties and rheology • Adsorption, Intercalation, Ionic exchange • Genesis and deposits of clay minerals • Geology and geochemistry of clays • Modification of clays and clay minerals properties by thermal and physical treatments • Modification by chemical treatments with organic and inorganic molecules(organoclays, pillared clays) • Modification by biological microorganisms. etc...
