Nanometer-sized Particles, Colloidal Solution and Adsorption-Exploration on the Genesis of Some Metal Deposits

Abstract: According to the significant change of the physical properties of nanometer-sized particles, the authors consider that aerosol, colloidal solution or solid solution, especially colloidal solution, formed by dispersion of dispersed phases in different dispersed media (gas, liquid or solid) is very important for the transport of ore? Juan Forming substances. For the transported colloidal particles, their coagulation or adsorption by other carrier minerals or rocks and concentration is a kind of important mineralization. This view is particularly conducive to explaining the genesis of finely disseminated gold deposits, placer gold deposits and some rare and dispersed metal deposits.
