中文摘要
该计划建议开发处理铁和磷酸盐矿石的有效方法。提出的工作涉及氧化铁-二氧化硅体系中的界面过程,具体目的是开发可使组分矿物选择性聚集的絮凝剂。研究主题包括表面活性剂和聚合物在矿物表面的吸附、与实际分离过程相似条件下的电动力学研究,以及具有羟基酸盐等官能团的絮凝剂在赤铁矿和粘土之间选择性絮凝分离的可能性。
英文摘要
The PI proposes to develop efficient methods of processing iron and phosphate ores. The proposed work deals with the interfacial processes in iron oxide-silica system with the specific purpose of developing flocculants that can produce selective aggregation of component minerals. Topics such as adsorption of surfactants and polymers on mineral surfaces, electrokinetic studies under conditions similar to those encountered in actual seperation processes and possibilities for selective flocculation seperation between hematite and clays by flocculants with functional groups such as hydroxamates will be investigated.
