The idea that vapor phase can transport metals was mentioned in 1644, but the research is very weak because of the lack of enough recognition and new microanalysis techniques and so on. In this paper, we review some recent experimental study and geologic evidence on the vapor transport of ore metals. It should be pointed out that vapor transport of ore metals relies on the interactions between metals and gas-solvent forming (chloride) hydrate of metals that enhance the solubility of metals in vapor phase, not totally due to the volatility of metals. So it is very important to continue the study of vapor transport of ore metals, especially weakly volatile elements. With the further study and the accumulation of base data, more attention will be paid to the important role of vapor transport of ore metals on the formation of ore deposits.
