Application of hydrothermal system solubility experiment and thermodynamic calculation method in metallogenic process simulation
摘要
Abstract
Hydrothermal fluids play a key role in transport,enrichment and deposition of the metallic elements,and therefore,quantitatively discretion of the hydrothermal mobility of metal elements has always attracted consider-able attentions.Hydrothermal experiments are one of the most effective ways to understand the behavior of the metallic elements in hydrothermal systems.The Ti-alloy-reactor solubility experiment,conducted under various physical and chemical conditions,combined with the related thermodynamic calculation,can accurately deter-mine the solubility,the complex coordination number,the partitioning coefficient between gas-liquid phases and the other related thermodynamic parameters of metal elements.The application of these thermodynamic dataset could effectively evaluate the mechanisms responsible for hydrothermal transport and deposition of the metal ele-ments.In this contribution,we review various hydrothermal experimental methods,and analyzes the advantages and disadvantages of various experimental and analytical methods.Combined with the study cases in scandium mineralization process,the solubility experiments conducted in titanium alloy fusion reactors are particularly in-troduced.This paper also summarizes current application status of this method in simulation of mineralization process,and the research trends are put forward in the end.This paper provides a comprehensive review of the Ti-alloy-reactor solubility experiments and the related thermodynamic calculation,and the existing problems of this method are explained,in order to promote the application and development of this method in simulation of the mineralization process,and so as to make a major breakthrough in the study of the mechanism of super-enrich-ment strategic key metals.关键词
