摘要
Abstract
A gold deposit in Gansu province is composed of auriferous sulfide ore in quartz vein. More than 70% gold is in coarse grain. In the fine grain gold occurs mainly as inclusion in pyrite and gangue minerals and is difficult to separate so higher gold grade is for the dailling. Gravity+floatation technique is not proper with poor recovery then finely grinding ( - 0. 074 mm grain size 95%) and one roughing + three scavenging technique and collector of YF-100 are tested with good good results. Au grade of the concentrate is 109. 8×10-6 and recovery 97. 24%.关键词
