Organization and Management of 

 Research Activities 



The Associate Director — Mineral and Materials 

 Research and Development is responsible for 

 management of all the Bureau's R&D programs 

 directed to the extraction, processing, use, and 

 disposal of minerals, and research related to min- 

 eral-based substances and their wastes. Guidelines 

 for research programs are developed by the Direc- 

 tor's staff in Washington from information on the 

 needs of the Nation for mineral materials. These 

 guidelines are sent to the various field organiza- 

 tions where research personnel initiate ideas and 

 proposals for achieving objectives identified in the 

 guidelines. Review of research ideas and proposals 

 is accomplished principally at the headquarters 

 staff level. Evaluation is conducted by the profes- 

 sional scientists and engineers of the Washington 

 headquarters staff. 



The Assistant Director — Metallurgy and the As- 

 sistant Director — Mining are the principal Bureau 

 of Mines authorities on current technology and 

 areas of research relating to mining and metallurgi- 

 cal processes. They also recommend and imple- 

 ment authorized research programs. 



Support of research by grant or outside contract 

 in industry, universities, and in nonprofit institu- 

 tions is determined after review. During the review 

 process, unsolicited proposals are appraised for 

 merit by members of the scientific and engineering
