Recycling Potentials of Critical Metals-Analyzing Secondary Flows from Selected Applications

Recycling of Precious Metals from E-scrap

Recovery of gold and other valuable metals from electronic scrap involves a complex metallurgical flow sheet and requires state-of-the-art recovery technologies that are available in large-scale, integrated smelter and refinery operations. At the end of their use, electronic and other electrical product scrap offer an important recycling potential for the secondary supply of gold and silver...

Analyzing Vulnerabilities Of Critical Infrastructures Using Flows And Critical Vertices In And/Or Graphs

AND/OR graphs and minimum-cost solution graphs have been studied extensively in artificial intelligence (see, e.g., Nilsson [14]). Generally, the AND/OR graphs are used to model problem solving processes. The minimum-cost solution graph can be used to attack the problem with the least resource. However, in many cases we want to solve the problem within the shortest time period and we assume tha...

Yet these divergences do not signify a structural difference in ways of thinking. In recent periods of contemporary society the so-called human studies Geisteswissen-scMften) have had but a fluctuating market value and must try to imitate the more prosperous n...
