Coal surface control for advanced fine coal flotation

Abstract

Thisresearch endeavor wastheresult ofconsiderable effort by all theparticipants involved, including discussion withThomasJ.Fceley III, DOE Contracting Officer's Representative, during the course of this research. The research conducted by eachof thedifferent subcontractors atthe various locations isdetailed inChapterI. Although theemphasis oftheproject was research, the preparation ofreports was paramount inmakingthis project a succa_s. The compilation ofdata and the writing of this report was, perhaps, the single most time-comuming task involved with this research project, and therefore we would like to acknowledge those who spent long hours writing, editing and preparing this report. A significant part of this final report is based on the project's First Annual Report, a good portion of which was written and coordinated by Vas Choudhry of Praxis Engineers, Inc.. The research group at Columbia University was responsible for summarzing their O work, which is reported in certain sections of Chapters 3, 5, 9, 10 and 12. Also, we would like to thank Jianli Diao of Berkeley, who not only wrote Chapter 11 but also contributed to many of the other chapters, helped edi'. a large part of the first draft, and assisted in the final revision. Guy H. Harris contributed to the sections on surface modification reagents. Special mention should also be made of Francisco Sotillo and Asoke De for their extensive proofing of the draft text and for preparing many of the figure. Finally, we would like to acknowledge Deborah Clark, who has over the course of this project been responsible for keeping track of ali text, tables, figures and data for ali of the reports that we have prepared; special acknowledgment is given for her organization in the preparation of this final document.
