U.S.-Turkey Cooperative Research: Recovery of Borax from Saturated Salt Solutions

产品描述：该奖项旨在表彰湖城犹他州大学冶金工程系的Jan米勒博士以及土耳其伊斯坦布尔技术大学采矿学院的Guven Onal和Mehmet Sabri Celik博士对合作研究的支持。 该研究旨在提高对硼矿物浮选化学的理解，更有效地利用硼资源，并最大限度地减少工艺操作对环境的影响。 具体来说，研究人员计划使用原子力显微镜（AFM）作为检查硼浮选中相互作用力的有力工具。 他们将测量硼酸盐矿石在不同浓度条件下、与粘土混合时以及在不同pH水平下在水中的相互作用力。 他们计划使用傅里叶变换红外光谱仪（FTIR）来检测阴离子和阳离子捕收剂在各种矿石和矿石混合物中的吸附。 还计划使用拉曼光谱来检测和描述浮选条件和结果。 适用范围：该奖项允许两个具有互补能力的研究团队合作，在美国和土耳其进行重要的科学工作，并在工业中应用。 这些团队将包括来自美国和土耳其的研究生。 这些研究将有助于开发一种浮选分离策略，以便更有效地从饱和溶液中回收硼矿物。 美国是硼化合物的最大生产国，土耳其拥有世界上最大的硼储量。 该项目完全符合国际方案司的目标。 该奖项包括来自国际项目部和化学和运输系统部的资金。

Description: This award is for the support of cooperative research by Dr. Jan Miller, Department of Metallurgical Engineering at the University of Utah, Salt lake City, and Drs. Guven Onal and Mehmet Sabri Celik, of the Mining Faculty, Istanbul Technical University in Turkey. The research aims at improving the understanding of the floating chemistry of boron minerals, to make more efficient use of boron resources, and to minimize the environmental impact of the process operations. Specifically, the investigators plan to use Atomic Force Microscopy (AFM) as a powerful tool for examination of the interaction forces in boron flotation. They will measure the interaction forces in borate ore in water under different conditions of concentration, when mixing with clays, and under different pH levels. They plan to use Fourier Transform infrared (FTIR) spectrometers to examine the adsorption of anionic and cationic collectors in various ore and ore-mixes. Also planned is the use of Raman Spectroscopy to detect and describe flotation conditions and results. Scope: This award allows cooperation of two research teams with complementary capabilities, to do important scientific work that has applications in industry, in the US and in Turkey. The teams will include graduate students from the US and from Turkey. The studies will contribute to the development of a flotation separation strategy for more effective recovery of boron minerals from saturated solutions. The US is the largest producer of boron compounds, and Turkey has the largest boron reserves in the world. The project fits well within the objectives of the Division of International Programs. This award includes funding from the Division of International Programs, and from the Division of Chemical and Transport Systems.
