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

目标和相关性：该项目是哥伦比亚大学 P. Somasudaran 博士和 Drs. P. Somasudaran 之间的合作研究。印度理工学院 (IIT) 孟买分校的 R. Mallikarjunan 和 S. Venkatachalam。 该项目旨在了解潜在的精细选矿技术（即电浮选）的机制，并将其开发用于选定问题矿石的选矿。 孟买印度理工学院在电化学和浮选技术方面的专业知识补充了哥伦比亚大学在调查中细粉浮选的表面和胶体化学方面的专业知识。 该研究将包括使用不同的电极设计，根据气泡尺寸和产生的电荷尺寸分布对选定的氧化物、盐类和硫化物矿物进行电浮选，并研究这些气泡与矿物的相互作用力。 美印计划支持两国科学家在 NSF 感兴趣的领域进行合作研究，预计合作会带来好处。该项目就属于这一类别。 优点：这位美国科学家是该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。 该研究领域解决了美国采矿业面临的一个重要问题，对印度也很重要。 资金：该项目由两项赠款资助：印度研究所。科技。孟买：INT 87-16926 印度货币 57,143 美元 哥伦比亚大学：INT 87-04303 印度货币 17,135 美元加 29,218 美元
