湿法冶金基础与应用

　　Fundamentals and principles of hydrometallurgical processes are described in this book. The basic concept of hydrometallurgy and the overview of nuneral processing technologies are first introduced. The basic principles on leaching， separation and purification，and recovery of metals is elucidated in detail.In the section of leaching，the thermodynamics and kinetics of various leaching processes， especially construction of Eh-pH diagram and kinetics modelling are introduced； In the section of separation and purification， the thermodynamics and kinetics behind solvent extraction， ion-ex-change resin， and adsorption by activated carbon are discussed； In the section of re-covery， the basic principles of cementation and electrowinning especially the electro-chemical theory are the emphasis. The relevant application of these principles in devel-oping extractive metals or metal products from ore or intermediate materials is also dis-cussed. The practice of leaching including various leaching methods is also focused.The book is aiming to help students of metallurgy majors or scholars in related fields to major in metallurgy or relevant fields to understand the basic principles of hydrometal-lurgy.
