甘肃省徽县洛坝金矿床矿石特征研究

The Study of the Ore Character of Luoba Gold Deposit Gansu Province

洛坝金矿床矿石工艺类型为贫硫化物全氧化含金矿石类型,矿石中金矿物为自然金及银金矿,有害元素炭品位为﹥0.1%,金矿物粒度细小,赋存状态以裂隙金为主,次为粒间金、包裹金;载金矿物主要为褐铁矿,粒度粗细不均,大部分粒度较细;通过对矿石质量研究,为选矿试验提供必要参数,并为矿床下步开发提供依据。

The technical types of the ore of the Luoba deposit is the gold ore types of poor sulfide and all oxidation,the gold mineral in the ore is gold and electrum,the content of Carbon as the deleterious element is above 0.1%.The gold mineral＇s granularity is exiguous,its being state is fissures at first,and then is intergranulars and entrainments;the mineral which carrying the gold element is limonite,it＇s granularity is asymmetrical,but exiguous in a great measure.By studying the ore quality,this article offered the necessary parameter for mill run and offered the gist for the exploitation of the deposit.
