摘要
Southern Anbali mining area is the section which attracts the most exploration in Yangshan gold deposit of Gansu.The ore bodies are hosted in the third lithology section of Devonian Sanhekou Group and controlled by the Anchanghe-Guanyinba fault system.The most important types of ores are altered phyllite and plagiogranite.Metal minerals account for 3.18%,such as pyrite,arsenopyrite and stibnite which are low-in-sulfur ores.The beneficial component is gold,while other beneficial components have no value of comprehensive usage.Most vehicles for gold are phyrite,and some are arsenopyrite.Gold minerals are produced in the form of Au in enclosing structure(most) and intergranular Au.The occurrence of gold is favorable for the flotation recovery.
