摘要
为了加强口岸固体废物监管,有效遏制固体废物非法流入我国,以一批因外观形态异常而受海关布控的含铜物料为案例,利用X射线荧光光谱和X射线衍射等分析方法,对该物料进行了固体废物属性鉴别研究。结果表明:样品主要含铁、硫、硅、钙、铜、锌等元素,样品主要物相为黄铁矿、闪锌矿、硫化亚铁、硫化锌铁、石膏、辉砷铜矿、吉硫铜矿、赤铜矿、铁矾、石英石、重晶石、黄钾铁矾等组分;综合样品外观和理化特性,结合相关文献资料和研判结果,最终推断该样品来源于天然铜矿、铁矿、锌矿及含铁锌多金属矿的混合物,未夹杂固体废物,为海关进口监管和资源有效利用提供了科学依据。
In order to strengthen the supervision of solid waste at ports and effectively curb the illegal flow of solid waste into China,a batch of copper-containing materials controlled by customs due to abnormal appearance were taken as cases,and the solid waste properties of the materials were identified by X-ray fluorescence spectroscopy and X-ray diffraction.The results show that the samples mainly contain iron,sulfur,silicon,calcium,copper,zinc and other elements.The main phases of the sample are pyrite,sphalerite,ferrous sulfide,zinc and iron sulfide,gypsum,arsenopyrite,chalcocite,hematite,jarosite,quartzite,barite,jarosite and other components.Based on the appearance and physical and chemical properties of the samples,combined with the relevant literature and research results,it is concluded that the samples are derived from natural copper ore,iron ore,zinc ore and iron-zinc polymetallic ore,without solid waste,which provides a scientific basis for customs import supervision and effective utilization of resources.
