Based on analysis experience for several years of more than 10000 samples with various content of gold from different gold deposits or gold survey areas, this paper brings forward systematical improvements of trace gold field rapid determination method, involved less operation processes, available and portable devises, by which, high speed and efficiency can be obtained without loss of precision and accuracy. According to Qeqott formula, combined with acquaintance of (super-) micro-fine gold deposits, proposes a solution to sample wight of trace gold field rapid determination, thus, the field rapid determination method can be applied to trace gold as well as exploration and development of target deposit.
