Abstract

Reprocessing sulfide minerals in tailings is an attractive option for sustainable tailings management. It can reduce the environmental impact generated by acid mine drainage while recovering valuable metals from tailings. Conventional mineral processing techniques often face challenges when it comes to reprocessing mine tailings, primarily due to factors such as particle size and surface oxidation. By addressing these challenges with targeted strategies, it’s possible to improve recovery efficiencies and make the reprocessing of mine tailings more economically viable and environmentally sustainable. Various advanced techniques are able to target specific tailing properties and achieve high recovery efficiency. This review paper covers various conventional mineral processing methods and their technological advances for reprocessing tailings as follows: (1) flotation with novel machines and reagents, (2) advanced gravity separation, (3) centrifugal dense medium separation, and (4) high-gradient magnetic separation.

利用矿物加工方法对硫化尾矿进行再加工以实现资源回收和防止 AMD 的综述

对尾矿中的硫化矿物进行再加工是可持续尾矿管理的一个有吸引力的选择。它可以减少酸性矿山排水对环境的影响，同时从尾矿中回收有价值的金属。在对矿山尾矿进行再加工时，传统的矿物加工技术往往面临挑战，主要是由于粒度和表面氧化等因素造成的。通过有针对性的策略来应对这些挑战，就有可能提高回收效率，使矿山尾矿的再处理更具经济可行性和环境可持续性。各种先进技术能够针对特定的尾矿特性，实现高回收效率。本文综述了以下各种传统选矿方法及其在尾矿再处理方面的技术进步：(1) 使用新型机器和试剂的浮选，(2) 先进的重力选矿，(3) 离心致密介质选矿，以及 (4) 高梯度磁选。

期刊介绍： The purpose of the journal is to provide for the rapid publication of topical papers featuring the latest developments in the allied fields of mineral processing and extractive metallurgy. Its wide ranging coverage of research and practical (operating) topics includes physical separation methods, such as comminution, flotation concentration and dewatering, chemical methods such as bio-, hydro-, and electro-metallurgy, analytical techniques, process control, simulation and instrumentation, and mineralogical aspects of processing. Environmental issues, particularly those pertaining to sustainable development, will also be strongly covered.
