Discussion on Modeling and Optimal Control of Nonferrous Metallurgical Purification Process
摘要
Abstract
Purification is an essential part of non-ferrous hydrometallurgy,which involves using additives to replace impurities in the leaching solution thus to provide highly purified solution for subsequent electrowinning.The performance of purification process largely affects the quality of final metal product and the stability of the entire hydrometallurgy process.Due to the diversity of concentrate sources and the complexity of removal reactions,it is difficult to realize high efficiency and green production.From the perspectives of technological features and reaction mechanisms,the common problems in modeling and optimal control of purification process are first extracted.Then the current status in modeling and optimal control of purification process are reviewed.Zinc hydrometallurgical purification process is described as a typical example to introduce the recent results of the author's group in modeling,optimization and control of iron precipitation,copper removal and cobalt removal processes.This paper ends with a perspective on the potential trends in the automation of nonferrous hydrometallurgical purification process.关键词
