Background technology
Activation of the substance in hydrothermal solution, migration, precipitation are mineralization geological process critically important in nature.People for a long time
Carry out the theory and experimental study of phase balance relationship mostly in terms of thermodynamics, it is complete it is many traditionally learn in theory,
Though these achievements help to understand and deepen mineralization, but still have significant limitation, and reach balance in closed system
Still gap is very remote between the actual conditions of steady-state model and nature.In fact, many geochemical process belong to it is irreversible
Thermodynamic process, in its motion process with country rock extensive energy and mass exchange activity occur for hydrothermal solution in the earth's crust, these ground
Matter effect all in opening, flowing, it is nonequilibrium under the conditions of.Therefore, certain pressure, temperature, pH, concentration of medium, fugacity are simulated
The Chemical Kinetics experimental study of current system dissolving and precipitation is mutually tied with current system scale-model investigation Deng under the conditions of
The research work of conjunction can just make research work turn to the system side of open separate equilibrium state by the closed system of stable state
Face makes it draw close major step to the actual conditions of nature, provides foundation for understanding ore deposit mechanism, makes geology from wooden
Static observation move towards dynamic experimental study living.
In contrast, experimental geochemistry is a very young subject.Since last century, different researchers is into ore deposit
Mechanism is studied from different perspectives, with the mechanism of epuilibrium thermodynamics methods experiment study of rocks, ore and mineral formation, is borrowed
Helped thermodynamic (al) tool-balance, static, closing concept, it is complete it is many traditionally learn in theory.Also once to it is certain into
The understanding of ore deposit geologic process has in-depth, but still has significant limitation.Because the geologic processes such as hydrothermal solution are places in the earth's crust
In an open system, it is nonequilibrium under the conditions of.Hydrothermal solution has extensive ability and substance in its motion process, with surrounding
It exchanges.Now, more and more geochemistry process have been found be chemical reaction velocity control process, it is then, non-equilibrium
Thermodynamics and chemical kinetics research geochemical field open a new research direction, much it is experimentally confirmed that non-flat
Weighing apparatus non-linear process is of great importance to Study on ore, mineral formation.
Ore-forming element is migrated and how to be migrated in geological process in what manner, is all geochemical educational circles all the time
The problem of most basic problem in science and fluid migration Mechanism Study can not avoid.Generally, it is considered that the geology dominated in fluid
In the process, element mainly exists and is migrated with corrdination type complex compound and polyacid type complex compound.Central ion and dentate
The environmental factors such as the internal factors such as property, activity, ligand field stabilization energy and temperature, pressure, pH, oxygen fugacity, sulfur fugacity all influence
The stability of complex compound, and migration of elements form and its stability influence and the precipitation mechanism that restrict mineral, then is added

Focus.
In addition to theoretical calculation and computer simulation, domestic and foreign scholars measure ore-forming element using mineral dissolution degree method mostly and exist
Existence form in hydrothermal solution.However, mineral dissolution degree principal measure is element can dissolve out in source region amount, element in fluid
The amount of migration and migration scale need to by stable migration form --- the stability of complex compound determines, and for such as Pb, Zn
Stability of the chloro-complex in BIFhosted gold deposit still lacks related and reliable infrastest data.At present, Hydrolyze method pair is utilized
The research of migration of element form be concentrated mainly on it is difficult return molten or do not return in molten high valence elements, such as Nb, Ta, Ti, Sn, but for easy
The stability constant that molten lead zinc is only capable of finding lead zinc complex in pure water at 25 DEG C is returned, after lacking the non-magma that carbonate rock holds ore deposit
Under raw hot-liquid type Lead-zinc Deposits Temperature-pressure Conditions（50~350 DEG C, 1~100MPa）NaCl-H2Related experiment number in O systems
According to.
In addition, the main reason for ore-forming element is precipitated from hydrothermal solution includes：Cooling, boiling, dilution, pH variations, oxygen
Change water/lithofacies interaction of reduction Eh variations, fluid mixing and generation wall rock alteration etc..Compared with above-mentioned other factors, fluid
It is blended in the formation of all kinds of hydrothermal deposits and has all played important function, it may be to the formation mechenism in announcement Large-super Large mineral deposit
It is of great significance.But current various precipitation mechanisms are based primarily upon mineralogy, petrology, isotope geochemistry, micro member
Plain geochemistry, Geochemistry of Fluid Inclusions, computer simulation and propose, there is no into the verification in terms of ore deposit experiment, especially
Dynamic process to precipitation is even more to know little about it, therefore the expansion of precipitation kinetics experiment may be to further investigate such mineral deposit
Another breach of mineralization machanism.
Pressure is usually higher during Ore-forming geology, especially by construction control based on mineral deposit in, stress into
The effect of ore deposit is often relatively more significant, because being up to 100MPa, and temperature is general into operating pressure needed for ore deposit experiment
Up to 300 DEG C or so, existing high-temperature high-pressure reaction kettle is caused to be difficult to reach a high temperature mostly the requirement of high pressure.Although there is part energy
Enough reach the reaction kettle of above-mentioned high temperature and pressure requirement, but due to simulation mineral precipitation during, need different temperatures, pressure, concentration,
Two kinds and secondary, the multiple or continuous on-line mixing charging with upper fluid of pH；And migration of element process is being simulated, to prevent two
Returning for valency element is molten, and on-line period is needed to be analyzed.But the reaction kettle that can bear high temperature and pressure at present does not have online add
Material and the function of sampling, and lack and control is planned as a whole to the automatic of entire analogue experiment installation, it seriously hinders to first into ore deposit
Element migration and the research of precipitation mechanism.
