Occurrence of gold in Shuangpengxi gold deposit in Qinghai and study on the beneficiation

Qingyun Liu

Abstract

Material composition of the Shuangpengxi gold deposit is complicated with abundant metal oxides and a few sulfides.The main gold-carriers are limonite,carbonate and quartz.Electrum and native gold are the individual gold minerals.Gold is mainly in coarse grain size and hosted in mineral fractures.Fine grinding can raise the recovery of gold.The recovery of floatation+syanidation technology is 91.7%.
