Abstract:

 Ore of the Dongan gold deposit is electrum ore that is strong silicification and poor sulphur, its mineral composition is simple. Being low content, metallic mineral pyrite accounts for 2.8%. The main metallic mineral is pyrite, minority is arsenopyrite, sphalerite, galena etc.. Quartz is Main gangue mineral, next is feldspar, kaolinite, chlorite, sericite, etc.. Most of gold mineral occurrence as intergranular gold, others are inclusions. The size of gold is mid and fine micrinite(84.6% gold is finem icrinite) predom inantly.
