摘要:
以多年逾万件不同金矿区、金矿普查区不同级次含量样品的野外分析测试为依据,提出了对痕量金野外快速测试方法的系统改进,提高了原分析方法的速度和效率,减省了不必要的操作流程,改装了部分设备,使其更易采购和便于携带,在降低劳动强度的同时也不降低分析的精密度和准确度。根据切乔特公式,结合对(超)微细粒金矿的认识提出了针对不同工作目的,痕量金野外快速测试称样的解决方案,既可分析痕量金,也可对目标金矿区作出快速准确的圈定,进而现场指导金矿的勘查开发。
Abstract:
Based on analysis experience for several years of more than 10 000 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, in-volved 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 so-lution 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.
