进口铜精矿属性鉴别过程中的思考

随着我国铜精矿进口量的日益增加及物料性质趋于复杂，有必要采用科学高效的方法对矿产品开展属性鉴别，来规避矿产品进口贸易中潜在的风险。本次对某疑似“掺杂明铜”的进口铜精矿开展物性鉴定，采用矿物自动分析仪（BPMA）、光学显微镜、X-射线衍射仪等综合手段查明了产品中的物质组成和结构特征，并从矿床成因、冶金机理、选矿工艺等多角度对该铜精矿的产出来源和生产工艺进行了深入研究和探讨，论证产品中未掺杂有冶金组分，最终确定其为天然铜精矿。从而协助了海关部门对该货源顺利通关，也保障了贸易双方的权益，实现境外战略资源的有效利用。

Thinking of characteristic identification of copper concentrate:A Case study of an imported copper concentrate

With the increasing import volume of copper concentrate and the complexity of material properties, it is necessary to use scientific and efficient methods to carry out attribute identification of mineral products to avoid potential risks in the import trade . The physical property discrimination of an imported copper concentrate suspected of '' doped metallic copper '' was studied. The material composition and structural characteristics in the product were identified by comprehensive means such as mineral automatic analysis system ( BPMA ), optical microscope and XRD. The origin and production process of the copper concentrate were discussed from the aspects of ore genesis, metallurgical mechanism and beneficiation process. It was demonstrated that the product was natural copper concentrate without doping metallurgical components. The results of this study Assisted customs to pass the goods smoothly, ensured the rights and interests of trade parties, and realized the effective utilization of overseas strategic resources.
