ABSTRACT:
Disclosed is a pyrometallurgical system and method for optimizing the interfacial contact in a two liquid system for promoting a reaction dependent upon such interfacial contact. Results are presented which indicate that, while the reaction rate initially increases rapidly with a mixing of the two liquids, excessive mixing produces little additional benefit in the reaction rate, can lead to damage of vessel walls, and can lead to a great increase in the "settling out" time of one liquid from the other (or even a complete emulsification). The specification identifies key parameters in the design of a suitable stirrer blade assembly and presents an analysis intended to yield an optimized blade design.
