Studies on Particle-Bubble Interaction in Relation to Fine Particle Flotation, Award in Indian Currency

目标和相关性：这个项目是哥伦比亚大学的P.Somasudaran博士与孟买印度理工学院的R.Mallikarjuan博士和S.Venkatachalam博士之间的合作研究。该项目旨在了解一种潜在的细粒选矿技术的机理，即电浮法，并将其开发用于精选问题矿石的选矿。印度理工学院、孟买在电化学和浮选技术方面的专业知识与哥伦比亚大学在浮选细粉的表面和胶体化学方面的专业知识相辅相成。这项研究将包括使用不同的电极设计，根据产生的气泡大小和粒度分布电荷，对选定的氧化物、盐类和硫化矿物的电浮选进行研究，并研究这些气泡与矿物的相互作用力。美国-印度计划支持两国科学家在NSF感兴趣的领域进行合作研究，因为预计该项目属于这一类别的合作将带来好处。优点：这位美国科学家是美国材料和矿物加工领域的顶尖科学家之一。印度理工学院孟买分校是印度著名的学术和研究机构之一。该研究领域涉及美国采矿业面临的一个重要问题，对印度也很重要。资助：该项目由两项赠款资助：印度研究所。理工学院。在孟买：印度货币为INT 87-16926美元57,143美元哥伦比亚大学：印度货币INT 87-04303美元17,135美元外加29,218美元

Objectives and Relevancy: This project is for a cooperative research between Dr. P. Somasudaran of Columbia University and Drs. R. Mallikarjunan and S. Venkatachalam of the Indian Institute of Technology (IIT) at Bombay. The project is aimed towards understanding the mechanisms of a potential fine beneficiation technique, namely, electroflotation and developing it for beneficiation of selected problem ores. The expertise in IIT, Bombay in electrochemistry and flotation techniques complement that at Columbia University in surface and colloid chemical aspects of flotation of fines in the investigation. The study will include the electroflotation of selected oxides, salt type and sulfide minerals as a function of bubble size and size distribution charge produced, using different electrode designs, and studiesof forces of interaction of such bubbles with minerals. The U.S.-India program supports cooperative research between scientists of the two countries in areas of interest to NSF when benefit is expected to result from the collaboration This project falls in that category. Merit: The U.S. scientist is one of this country's top scientists in the field of materials and minerals processing. IIT Bombay is one of India's prestigious academic and research institutes. The research area deals with an important problem facing the mining industry in the U.S. and is also important to India. Funding: The project is being funded under two grants: The Indian Inst. of Tech. at Bombay: INT 87-16926 $57,143 in Indian currency Columbia University: INT 87-04303 $17,135 in Indian currency plus US$29,218
