摘要： 为了给含砷金矿的提金工艺流程提供理论依据,对广西金牙金矿的矿石开展了工艺矿物学研究.该矿是典型的含砷难浸复杂金矿,矿石含Au为6.28 g/t,含Ag为1.37 g/t.As的质量分数为0.58%,S的质量分数为3.10%,C的质量分数为1.76%,其中有机碳的质量分数为0.21%.金精矿含Au为52.61 g/t,含Ag为6.00 g/t.As的质量分数11.32%,S的质量分数为29.32%,C的质量分数为0.35%.矿石中的主要金属矿物为毒砂、黄铁矿,其次有方铅矿、闪锌矿和黄铜矿等.载金矿物主要有毒砂、黄铁矿;金的赋存形态为次显微金;矿石的有害组分为砷、碳质和黏土矿物.含砷矿物是以毒砂、...

Abstract: Jinya gold mine in Jinya, Guangxi Province PRC is of refractory type, in which the Au and Ag contents are 6.28 g/t and 1.37 g/t, respectively. The rest includes As 0.58wt%, S 3.10wt%, and C 1.76wt% containing TOC 0.21wt%. In the gold concentrate the Au content is 52.61 g/t, Ag 6.00 g/t, As 11.32wt%, S 29.32wt%, and C 0.35wt%. It was found that the main metallic minerals in Jinya gold ore are pyrite and arsenopyrite and the rest includes galena, sphalerite and chalcopyrite, etc. The main gold-bearing minerals are pyrite and arsenopyrite, and the occurrence form of gold in the ore is sub-micro grain gold. The main arsenic-bearing minerals are pyrite, realgar and orpiment. The objectionable constituents are arsenic, carbon-containing material and clay minerals. The characteristics of the gold ore are fine-grain granular texture and minuteness dip-dye structure.
