自然金的嵌布特征
经重砂分离和显微镜下观察得到金的嵌布特征(见表3)。从该表可以看出,自然金主要为中细粒可见金,嵌布在褐铁矿、磁赤铁矿、铅铁矾、黄铁矿(假象)、石英等矿物颗粒间及裂隙中,为粒间金和裂隙金,次为微粒金,主要呈微粒嵌布或包裹于褐铁矿及磁铁矿集合体中,粒径<0.01mm。
金的赋存状态
金的赋存状态见表4。金主要产于褐铁矿、磁铁矿、黄铁矿中,占总量的79169%,这说明金与上述矿物关系密切,这些矿物是金的主要载体矿物。在铅、锌矿物中金含量占20.32%,是金的次要载体,脉石矿物中Au的含量较少。

The heavy separation and microscope have shananbang gold (see Table 3). From the table can be seen, natural gold is mainly fine grained visible gold, block cloth in limonite, magnetic hematite, plumbojarosite, pyrite (false), quartz and other mineral particles and fracture, intergranular gold and fissure gold, gold particles were mainly particles embedded cloth or wrapped in limonite and magnetite in the aggregation, particle size less than 0.01mm.

The occurrence state of gold is shown in table 4. Gold occurs mainly in limonite and magnetite, pyrite, accounted for a total of 79169%. That is to say, the gold and the mineral relations closely. The mineral is the main carrier mineral of gold. The content of gold in lead and zinc minerals accounted for 20.32%, is the main carrier of gold, less content of gangue minerals in Au.
