Abstract

Abstract

Simulate experiments of gold precipitated by lowering temperature and changing salt-content are designed by simplifying experimental system and separating influential factors in order to study two main mechanisms of gold precipitated by fluid-mixing function. The study shows first of all that the Au content in solution is lower with the falling temperature of solution, with a kind of complex functional relationship between them, and 300 ℃ as the most significant temperature in geology for gold mineralization.Second, lowering the salt content of the Au-fluid reduces the content of complex foundation, and lead to the gold precipitating. Third, the alkalic metasomatism in the rock is beneficial to gold mineralization.
