项目摘要

One of the challenges within the copper mining industry is the lack of an economically and environmentally viable hydrometallurgy process for the treatment of copper sulphide concentrates. The existing technology, pressure oxidation process, suffers from high operating and capital costs. The only commercial alternative to pressure oxidation options is the Albion process, which was commercialized for copper recovery in Africa in December 2017. However, the weakness of Albion with respect to copper treatment is the lack of options for gold recovery. The successful testing, optimization and integration of the processed process to the acidic Albion leach process will make the process more attractive for the treatment of gold-containing copper concentrates. This research proposal aims to develop two very important add-on technologies to improve the application of the Albion leach process for copper concentrates, as well as gold concentrates. Herein, it is proposed to apply a newly developed carbon based bead, AF 5, as a sulphur adsorbent, to remove the elemental sulphur form the acidic Albion leach processes to reduce its environmental impact and improve the gold recovery process efficiency.
铜矿开采行业面临的挑战之一是缺乏一种经济上和环境上可行的处理硫化铜精矿的湿法冶金工艺。现有的加压氧化工艺存在操作成本和资金成本高的问题。压力氧化的唯一商业替代方案是Albion工艺,该工艺于2017年12月在非洲商业化,用于铜回收。然而,在铜处理方面,阿尔比恩的弱点是缺乏黄金回收的选择。该工艺对酸性Albion浸出工艺的成功试验、优化和整合,将使该工艺对含金铜精矿的处理更具吸引力。这项研究计划旨在开发两项非常重要的附加技术,以改善阿尔比恩浸出工艺对铜精矿和金精矿的应用。在此基础上,提出了采用新开发的碳基球团af5作为硫吸附剂,去除酸性白钨浸出过程中的单质硫,以减少其对环境的影响,提高金回收工艺效率。
