US-Turkey Cooperative Research: Flotation Technology for the Trona Industry

0096920Miller描述：该奖项是为了表彰犹他州盐湖城犹他大学冶金工程系Jan D.Miller教授和土耳其伊斯坦布尔技术大学(ITU)采矿工程系Mehmet S.Celik博士的合作项目。他们计划研究一种新的浮选技术在选矿过程中的应用，以去除不溶性污染物。特罗纳是纯碱的来源，广泛用于许多消费品。目前的回收方法包括通过传统的地下或溶液采矿方法提取Trona，在这两种情况下，矿石都会被溶解以去除杂质。直到最近，犹他大学发现了一种独特的浮选工艺，允许进行这种前处理，才有可能通过浮选进行前处理。利用这一工艺进行TRONA的预浓缩，将有效利用TRONA资源，并将工艺操作对环境的影响降至最低。范围：合作者将结合他们在这项研究中的专业知识，并将建立在早期在可溶性盐浮选领域的成功合作的基础上。拟议的工作应该会产生一种比现有方法更有效、更环保的提取天然有机钠的程序。该项目对美国和土耳其有潜在的好处，因为美国是最大的trona生产国，土耳其在trona储量方面排名第二。参与该项目的研究人员和机构以其在可溶性盐浮选领域的贡献而闻名。该项目符合支持互惠合作项目的INT标准。该项目由国际方案司和化学与运输系统司资助。

0096920Miller Description: This award is for support of a cooperative project by Professor Jan D. Miller, Department of Metallurgical Engineering, University of Utah at Salt Lake City, Utah and Dr. Mehmet S. Celik, Mining Engineering Department, Istanbul Technical University (ITU), Istanbul, Turkey. They plan to study the application of a new floatation technique in the processing of trona ore to remove insoluble contaminants. Trona is the source of soda ash, which is widely used in many consumer products. Current methods of recovery involve extraction of trona by conventional underground or solution mining methods, and in both cases the ore is dissolved to remove impurities. Preprocessing by floatation has not been possible until recently, when a unique flotation process was discovered at the University of Utah to allow for such preprocessing. Utilizing this process for preconcentration of trona, will make efficient use of trona resources, and will minimize the environmental impact of the process operations.Scope: The collaborators will combine their expertise in this research and will build on earlier successful collaboration in the area of soluble salt flotation. The proposed work should result in a procedure, for trona extraction, that is more efficient, and more environmentally benign than existing methods. The project has potential benefits to the United States and Turkey, because the United States is the largest producer of trona and Turkey ranks second in terms of trona reserves. The researchers and institutions involved in the project are well known for their contribution in the area of soluble salt flotation. The project meets INT criteria for support of cooperative projects that are mutually beneficial. This project is funded by the Division of International Programs and the Division of Chemical and Transport Systems.
