9811004MillerDescription: This award is for support of a cooperative project by Professor Jan Miller of the Department of Metallurgical Engineering at the University of Utah in Salt Lake City, Utah and Dr. Ahmed Yehia of the Mineral Technology Department at the Central Metallurgical Research and Development Institute in Cairo, Egypt. The two scientists will study flotation mechanisms and technologies with the goal of improving phosphate rock flotation strategy. Experiments will include bench scale flotation, enzyme catalysis, flotation of phosphate fines, column flotation, air-sparged hydrocyclone flotation systems, and immobilized enzyme utilization. Fundamental studies will include adsorption measurements of enzyme at the surface of mineral, surface characterization of ore conditioned in fatty acids and enzyme solution, evaluation of the hydrophobic character of autoxidized surface.Scope: This award will allow collaboration between a well known US metallurgist with extensive experience in the study of material processing and an active group at Egypt's main governmental center of metallurgical research. The benefit of this research would be significant to phosphate producing countries including the United States, Egypt and several other countries in the Middle East. Especially important is the benefit to producers using relatively low-grade ore as in Egypt, and those who need to obtain the maximum product from the same grade of ore. This proposal meets the INT objective of increasing US-foreign collaboration in areas that benefit both sides. This project is being supported under the US-Egypt Joint Fund Program, which provides grants to scientists and engineers in both countries to carry out these cooperative activities.

9811004Miller 描述：该奖项用于支持犹他州盐湖城犹他大学冶金工程系 Jan Miller 教授和中央冶金研究与发展研究所矿物技术部 Ahmed Yehia 博士的合作项目在埃及开罗。 两位科学家将研究浮选机制和技术，目标是改进磷矿浮选策略。 实验将包括实验室规模浮选、酶催化、磷酸盐细粉浮选、柱浮选、空气喷射水力旋流器浮选系统和固定化酶利用。 基础研究将包括矿物表面酶的吸附测量、在脂肪酸和酶溶液中调节的矿石的表面表征、自氧化表面的疏水特性的评估。 范围：该奖项将允许一位著名的美国冶金学家与广泛的合作在材料加工研究方面拥有丰富的经验，并且是埃及主要政府冶金研究中心的一个活跃小组。 这项研究对于包括美国、埃及和中东其他几个国家在内的磷酸盐生产国来说意义重大。 尤其重要的是，对于像埃及这样使用相对低品位矿石的生产商以及那些需要从相同品位矿石中获得最大产品的生产商来说，这将带来好处。 该提案符合诚信部在对双方有利的领域加强美外合作的目标。 该项目得到了美国-埃及联合基金计划的支持，该计划向两国的科学家和工程师提供赠款以开展这些合作活动。
