• Provide technology to increase the portion of 

 U.S. metal and mineral needs met by second- 

 ary resources. 



• Develop recovery techniques and stimulate a 

 significant increase in recycling metal and 

 nonmetallic materials from industrial and 

 obsolete consumer scrap materials. 



• Develop a better technologic base for metal- 

 lurgical processing systems so that appropri- 

 ate environmental regulations and control 

 technologies can be implemented which will 

 prevent environmental degradation without 

 unnecessarily restricting efforts by the miner- 

 als industry to meet the Nation's mineral 

 needs. 



• Effectively minimize the undesirable environ- 

 mental effects that can result from mineral 

 processing operations by providing better 

 processing technology. 



• Evaluate, demonstrate, and promote expand- 

 ed use of secondary materials in various me- 

 tal alloys or nonmetal products. 



• Anticipate and project new scrap materials to 

 allow early development of processing and 

 recovery techniques. 



Listed below are some promising or vital areas 

 of research, not now supported but involving basic 

 research, that warrant increased emphasis and 

 support: 



• Deep brine scaling mechanisms and kinetics 



• Simulation of experimental metallurgical and 

 engineering research using computer model- 

 ing. 



• Magnetic and electrostatic advanced mechan- 

 isms that have potential for separation of the 

 mineral constituents of low-grade and com- 

 plex ores.
