摘　　要：工艺矿物学研究是侦破形形色色的矿产品掺假案的重要手段。本文以某铅精矿掺假案为例,研究并提供了该铅精矿掺入银粉的证据。研究发现,铅精矿中的银主要为大颗粒自然银、呈单体状,尚没有完全分散开,周围的硫化银呈皮壳状、放射状。以上特征在自然界产出的铜铅锌精矿中是不存在的。Process mineralogy is a very important method in detecting the adulteration in the field of mineral production. The paper, taking the adulterating lead concentrate as an example, discussed our study on revealing the evidence of the lead concentrates adulterated with silver powder. Our study indicated that most of the silver in lead concentrate occurs in the form of coarse particle, unlocked particle, uncomplete dispersion, crust or radial shape of silver sulphide. All these forms mentioned above are not existed in Cu, Pb and Zn concentrates.
