太白庙小型岩金矿床位于南秦岭印支褶皱带,东川─云镇复向斜中部。矿体呈似层状、脉状、透镜状,赋存于星红铺组变泥钙质石英粉砂岩中,受层位、岩性和NWW向次级断裂带的控制。矿化与黄铁矿化、硅化、绢云母化、绿泥石化关系密切。金主要以自然金矿物形式存在,或包裹或充填于黄铁矿、石英、铁方解石、绢云母晶隙及裂隙间。成矿物质主要来源于容矿地层,成矿热液属大气降水热液。成矿温度低,压力小。在矿床地质特征上,经初步研究认为属于岩浆变质低温热液石英脉型金矿床.经混汞、重选、氰化浸出及堆浸半工业试验,金回收率较高,且选矿工艺简单,工业利用可行。
The Taibaimiao small-scale gold deposit is located in the middle part of the Indosinian fold belt in South Qinling and the syncline syncline in Dongchuan-Yunzhen. The orebodies are stratified, vein-shaped and lenticular and occur in the calcareous quartz siltstone of Xinghongpu Formation, controlled by horizon, lithology and NWW sub-fault zone. Mineralization and pyrite, silicification, sericitization, chloritization close. Gold is mainly in the form of natural gold minerals, or wrapped or filled in pyrite, quartz, iron calcite, sericite crystal crevices and cracks. Metallogenic materials mainly come from the ore-hosting strata. Mineralization hydrothermal fluids belong to the hydrothermal fluid of atmospheric precipitation. Metallogenic temperature is low, pressure is small. In the geological characteristics of the deposit, preliminary studies suggest that it belongs to magmatic metamorphic low-temperature hydrothermal quartz vein type gold deposit. After amalgam, re-election, cyanide leaching and heap leaching semi-industrial test, gold recovery is high, and the beneficiation process is simple, industrial use feasible.
