一、前言 江西某锑矿属低温偏中温热液辉锑矿矿床。矿体主要产于该区浅变质岩的破碎带中,且与脉岩——煌斑岩密切共生。矿体沿破碎带另星分布,呈透镜状、网脉状及脉状产于蚀变煌斑岩中。含矿带长300余米,宽40米,含矿率24.52％,矿体长数米至数十米不等,也有长不足一米的小矿体。矿化带中矿石品位变化较大,高者达40％以上,低者仅1％,总的矿石品位较富。据初步探明,锑的金属储量C_1+C_2=×万吨,平均品位7.05％,伴生综合利用元素主要为金。
I. Preface An antimony mine in Jiangxi is a low-temperature partial-temperature hot-liquid stibnite deposit. The ore body is mainly produced in the crust of the metamorphic rocks in the area and closely interbedded with the veins of the lamprotite and lamprophyre. The ore body along the broken with another star distribution, was lenticular, reticulate veins and veins produced in the altered lamprophyre. Mineralization belt length of 300 meters, 40 meters wide, ore-bearing rate of 24.52%, ore length from several meters to tens of meters, but also less than one meter long small ore body. The grade of ore in the mineralization zone varies a lot, the highest one is over 40%, the lower one is only 1%, and the total ore grade is richer. According to preliminary proof, the metal reserves of antimony C_1 + C_2 = × tons, the average grade of 7.05%, accompanied by comprehensive utilization of the main elements of gold.
