Study on the Occurrence State of Au in Yi Shan Gold Deposit
Yishan Gold deposit is located diorite rock mass and the formation of outside contact zone during middle variscan, which is medium-low temperature magmatic hydrothermal type deposit.Extensive movement of post-magrnatic hydrothermal fluids make Au, Ag and other ore-forming elements be concentrated to form deposits in the secondary tectonic belt and other space.This paper mainly through Hand specimen sample statistics, phase analysis, electronic probe, EDS analysis etc.comprehensive technical means studies the occurrence state of gold in gold ore.The results showed that, The mineral composition is simple, gold content is mainly electrum, Au in the ore exists mainly in the form of natural gold.The form of natural gold takes the round granula, angle of granular, grain shape, columnar and irregular shape etc.Natural gold is mainly in the form of fissure gold and wrapped gold which are inlayed in the iron oxide, sulfide and quartz.
