U.S.-Egypt Cooperative Research: Recovery of Phosphates from Their Wastes by Column Flotation

产品描述：该奖项是为了支持由佛罗里达大学材料科学与工程系教授兼NSF粒子科学技术工程研究中心（ERC）研究副主任哈桑埃尔-沙尔博士领导的美国团队&和由阿兹扎博士领导的埃及团队的合作项目。Youssef，矿物技术教授，中央冶金研究与发展学院（CMRDI）在埃及开罗。 ERC和CMRDI团队计划使用更有效的技术进行系统研究，以从埃及磷酸盐浓缩的尾矿中回收磷酸盐价值。 埃及磷酸盐的选矿产生尾矿，这些尾矿被处置，尽管它们含有细磷酸盐，其等级高于世界许多其他地区的植物饲料。 由于其细粒度和粘土含量，机械细胞不能回收此类材料。 浮选技术，如柱浮选将被研究作为从尾矿中回收细粒磷酸盐的方法。 该项目将开发一个小型试验工厂，供埃及的小型工业进一步评估其他材料。 适用范围：该奖项将允许埃及和美国科学家之间的合作，他们具有开展拟议研究所需的互补能力。 CMRDI将执行具体任务，包括调查埃及的资源和需求，样本收集和表征，建造中试规模的色谱柱，中试测试和模型评估，以及经济评估。 ERC将进行参数研究、模型开发和优化，并将与CMRDI合作培训埃及人员。 这两个合作团队在材料加工领域具有良好的资质和经验。 美国团队在细颗粒物研究和处理方面特别有经验。 这一提议符合INT的目标，即在有利于双方的领域增加美国与外国的合作。 该项目得到了美国-埃及联合基金方案的支持，该方案向两国的科学家和工程师提供赠款，以开展这些合作活动。

Description: This award is for support of a cooperative project by a US team headed by Dr. Hassan El-Shall, Professor in the Department of Materials Science and Engineering and Associate Director of Research in the NSF Engineering Research Center (ERC) for Particle Science & Technology at the University of Florida and an Egyptian team headed by Dr. Aziza A. Youssef, Professor of Mineral Technology, Central Metallurgical Research and Development Institute (CMRDI) in Cairo, Egypt. The ERC and CMRDI teams plan to conduct a systematic study using more efficient techniques to recover phosphate values from tailings from beneficiation of phosphates in Egypt. Beneficiation of Egyptian phosphate produces tailings, which are disposed of, despite the fact that they contain fine phosphate, whose grades are higher than plant feed in many other parts of the world. Because of its fine size and clay content, mechanical cells can not recover such materials. Flotation techniques such as column flotation will be studied as methods for recovery of fine phosphates from tailings. A small pilot plant will be developed in this project and would be available for small industries in Egypt for further evaluation of other materials. Scope: This award will allow collaboration between Egyptian and US scientists who have complementary capabilities which are needed to carry out the proposed research. The CMRDI will carry out specific tasks including surveys of resources and needs in Egypt, sample collection and characterization, the construction of a pilot scale column, pilot testing and model evaluation, as well as economic evaluation. The ERC will carry out parametric studies, model development and optimization, and will work with the CMRDI on training of Egyptian personnel. The two collaborating teams are well qualified and experienced in the area of material processing. The US team is especially experienced in fine particulate studies and processing. 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.
