Interrelated data for five fundamental features of production processes would help promote the- development of the discipline and profession of extractive metallurgy._x000D_
The features are the input materials, the products, equilibria, kinetics" and movement of materials within the reactor. Aspects of overall process performance that could be developed in these terms include quantitative comparison of reactor engineering options, process dynamics, interruptions to operations, and recycling. The ability to be able to forecast these and other aspects of process performance would be valued by most metallurgists. Although data have been reported for each of these aspects they have been more relevant to process economics than process fundamentals. The data have not often been interrelated via the fundamental features for a particular raw material-process system; nor have ~ similar data been related for different systems.
