AMICS在铜矿伴生金银综合回收中的应用

某铜矿石中铜品位为0.53%,其中伴生有价元素金、银的品位分别为0.11 g/t和2.76 g/t,虽然相对较低,但仍具有一定的综合回收利用价值。运用AMICS(Advanced Mineral Identification and Characterization System)对该铜矿中的伴生金银进行了赋存状态研究。查明了该矿石中金银矿物的种类、金银矿物的嵌布特征和嵌布粒度,以及影响它们回收的最主要因素,为其综合回收提供了理论依据。

APPLICATION OF AMICS ON COMPREHENSIVE RECOVERY OF ASSOCIATED GOLD AND SILVER IN COPPER MINE

The grade of Cu in a copper ore is 0.53%. As the associated valuable elements, the grade of gold and silver is 0.11g/t and 2.76g/t respectively. Although it is relatively low, but it also has a certain value of comprehensive recovery and utilization. AMICS (Advanced Mineral Identification and Characterization System) was used to systematically study the process mineralogy of associated gold and silver in this copper mine. The occurrence state of associated gold and silver in the copper ore is studied by AMICS (Advanced Mineral Identification and Characterization System). The types of gold and silver minerals, the distribution characteristics of gold and silver minerals, and the size distribution of the gold and silver minerals, as well as the main factors affecting the recovery of gold and silver minerals were determined, which provide a theoretical basis for the comprehensive recovery.
