Abstract

The increased exploitation of ores leads to the generation of mining waste, which has a negative impact on the environment and human health. For this reason, it is necessary to take care of it in an adequate way by applying some of the possible treatments. In addition to protecting the environment by applying appropriate treatment, there is also the possibility of making a profit by valorizing useful elements from mining waste. In order to choose the most adequate treatment, it is necessary to perform the characterization of mining waste. This paper contains a detailed characterization of the flotation tailings deposited at the Old Flotation Tailings in eastern Serbia, originating from copper ore processing. Characterization includes physico-chemical analysis, polarizing microscope analysis, X-ray Diffraction analysis (XRD) and Scanning Electron Microscopy with Energy Dispersive Spectroscopy (SEM-EDS) analysis analysis. The obtained results indicate that the investigated flotation tailings can be used as a secondary raw material for metal recovery, in this case primarily copper (whose content is about 0.24%), gold (with a content of about 0.43 ppm) and silver (with a content of about 1.7 ppm). Considering that the content of valuable elements is quite low, it is suggested to apply hydrometallurgical treatment for their recovery.

将铜金矿浮选尾矿（塞尔维亚博尔）作为有价金属回收的潜在二次原材料

矿石开采量的增加导致采矿废物的产生，对环境和人类健康造成负面影响。因此，有必要通过一些可能的处理方法对其进行适当的处理。除了通过适当的处理方法保护环境之外，还可以通过对采矿废料中的有用成分进行估值来获得利润。为了选择最适当的处理方法，有必要对采矿废料进行特征描述。本文详细描述了沉积在塞尔维亚东部老浮选尾矿的浮选尾矿的特征，这些尾矿源自铜矿加工。特性分析包括物理化学分析、偏光显微镜分析、X 射线衍射分析 (XRD) 和扫描电子显微镜与能量色散光谱分析 (SEM-EDS)。所得结果表明，所调查的浮选尾矿可用作金属回收的二次原料，在这种情况下，主要是铜（含量约为 0.24%）、金（含量约为 0.43 ppm）和银（含量约为 1.7 ppm）。考虑到有价元素的含量很低，建议采用湿法冶金处理来回收这些元素。
