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.

投资促进局建议开发处理铁矿石和磷矿的有效方法。这项工作涉及氧化铁-二氧化硅体系的界面过程，其特定目的是开发能够产生组分矿物选择性聚集的絮凝剂。课程将探讨表面活性剂和聚合物在矿物表面的吸附、在类似于实际分离过程中遇到的条件下的电动研究以及具有异羟甲酸酯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。
