广东陆丰硫铁矿床中伴生铜、金、银、碲、铋赋存状态研究

广东陆丰硫铁矿床为一个中低温热液交代充填型脉状矿床。伴生有综合利用价值的Ｃｕ、Ａｕ、Ａｇ、Ｔｅ、Ｂｉ等元素。其中Ａｕ主要呈微细粒自然金、次显微金包裹在黄铁矿中，Ａｇ主要呈自然银、螺状硫银矿等独立矿物充填在脉石矿物中。Ｔｅ、Ｂｉ呈碲铋矿、硫盐矿物嵌布在黄铁矿或充填在黄铁矿微裂隙中。多数硫盐矿物为矿区首次发现。通过矿石物质组分的研究，查清了上述元素的赋存状态，为硫铁矿床的综合评价，有益组分的合理回收提供了依据

OCCURRING STATUSES OF CU,AU,AG,TE AND BI ASSOCIATED WITH THE LUFENG PYRITE DEPOSIT IN GUANGDONG

The Lufeng pyrite deposit in Guangdong, a vein filling, micro mesothermal,metasomatic deposit, accompanies such comprehensively usable elements as Cu,Au,Ag,Te and Bi. The Au occurs mainly as micro or fine native gold in the pyrite while the Ag fills into the gangue minerals, taking the shape of separated native silver, acanthite and the like. The Te and Bi as tellurobismuthite or sulfosalts fill into the pyrite or inset into its cracks. Most of the sulfosalts are discovered for the first time. Investigation into the material composition of the ores has made clear how the above elements occur, thereby providing important basis for reasonably appraising the deposit as well as for efficiently revoverying its associated useful elements.
