摘要
针对海南抱伦金矿金回收率低等问题,对该矿石开展选矿试验研究。根据矿石中部分颗粒金粒度较粗的特点,采用重选-全泥氰化联合工艺流程,在原矿含金5.09 g/t时,最终获得了金精矿金品位83.15 g/t,金总回收率95.03%的较好指标,为选厂技改和扩建提供了依据。
Beneficiation tests were carried out against low gold recovery of Baolun Gold Ore in Hainan. Part of gold in ore exists as coarse native gold particle, gravity concentration and cyanidation leaching process were used to process the raw ore containing 5.09 g/t gold. Finally a marketable concentrate with Au grade 83.15 g/t and recovery of 95.03% was obtained. The study provides a reasonable processing technical renovation and gives reference to dressing plant expansion in the future.
