| 摘 要： | 采用"重复分析测定-筛上残金比-人工重砂鉴定"的方法判断矿石样品中的金是否以微细粒级形式均匀分布,此法可用于指导分析样品制样,提高小试样品的代表性。方法用于金厂金矿标准物质候选物检验,根据小试样品的粒度实验结果选用180目筛和50%过筛率进行人工过筛实验,筛下样品经球磨混匀后可作为该矿金矿石标准物质。

| Abstract: | Adopted a“repeat analysis-sieves residual gold ratio-heavy mineral artificial identification”approach to determine whether the gold in ore samples is uniformly distributed in the form of micro fine particles. The method can guide the analysis of sample preparation, and improve the representative sample test. Selection of 180-mesh sieve and 50%rate for manual sifting experiment, the samples were mixed by ball milling and can be used as the reference material of the gold ore. |
