Description: This project supports a cooperative project by a US scientist, Dr. Brij Moudgil, and Dr. Michael L. Free, a Post doctoral Research Fellow, at the Department of Materials Science and Engineering, at the University of Florida, Gainesville, and Dr. N.C. Chaudhuri and Dr. Pradip, of the Tata Research Development & Design Centre (TRDDC) in Pune, India. The objective of this research is to understand the basic mechanisms involved in selective adsorption of hydroxamate and fatty acid reagents in the iron oxide-titania systems. Physical and surface chemical characterization would involve x-ray, SEM, pore size distribution and electrokinetic measurements. Adsorption, FT-IR and microflotation tests would be conducted to identify the conditions for achieving the desired separation. Selectivity observed would be explained on the basis of conditional stability constants, crystal structure specificity and molecular orbital considerations. It is expected that the fundamental knowledge base generated in this study would be useful in scientific design of reagent schemes for processing of low grade complex ores. Scope: This project allows cooperation of two well known scientists whose capabilities complement each other and who work in institutions with complementary facilities for the proposed research. Dr. Moudgil is the director of the newly established Engineering Research Center for Particle Science and Technology at the University of Florida. He has had extensive list of research publications, including some with Pradip. The collaboration with Dr. Chaudhri is new and is likely to benefit both institutes. This project meets a number of important objectives of the Division of International Programs, especially in bringing in new participants to the international colaboration, and in the international exposure of a new U.S. Post Doctoral Fellow.

产品描述： 该项目支持美国科学家Brij Moudgil博士和Michael L. Free博士是位于盖恩斯维尔的佛罗里达大学材料科学与工程系的博士后研究员。印度浦那塔塔研究开发设计中心（TRDDC）的Chaudhuri和Pradip博士说。 本研究的目的是了解在氧化铁-二氧化钛系统中选择性吸附异羟肟酸和脂肪酸试剂的基本机制。 物理和表面化学表征将涉及X射线、SEM、孔径分布和电动测量。 将进行吸附、FT-IR和微浮选试验，以确定实现所需分离的条件。 观察到的选择性将解释的基础上的条件稳定常数，晶体结构的特异性和分子轨道的考虑。 本研究所建立的基础知识库，可为低品位复杂矿石选矿药剂方案的科学设计提供参考。 适用范围：该项目允许两名知名科学家合作，他们的能力相互补充，并在具有互补设施的机构工作。 Moudgil博士是佛罗里达大学新成立的粒子科学与技术工程研究中心的主任。 他有广泛的研究出版物，包括一些与Pradip。 与乔杜里博士的合作是新的，可能会使两个研究所受益。该项目符合国际项目司的一些重要目标，特别是在引进新的参与者到国际合作，并在新的美国国际曝光博士后研究员。
