项目摘要
Due to the depletion of high grade ores, production of metals necessitates processing of lower grade ores with increasing levels of arsenic. Processing this type of raw materials introduces arsenic into the metallurgical circuits, resulting in the generation of waste streams that contain arsenic, which is toxic and carcinogenic. In partnership with BQE Water, a water treatment service provider with expertise in mine impacted water and process solution treatment and management, we propose to enhance a sulphide-based precipitation process that removes and stabilizes arsenic as arsenic trisulphide with high arsenic content. Compared with the existing removal methods, this sulphidization process will generate the least volume of arsenical waste by-product due to the high arsenic content, which could reach as high as 60%, a substantial increase from the 5-30% content that results from current methods. However, the stability of arsenic trisulphide is a major concern due to its solubility and susceptibility to atmospheric and bacterial oxidation. Therefore, the key technical challenge the proposed project will address is to assess and devise a strategy to enhance the stability of the arsenic trisulphide under a variety of conditions, specifically those relevant for safe storage in the field. The enhanced sulphidization process aligns well with the strategic technology development at BQE Water. The new knowledge generated will strengthen the existing expertise and facilitate its business in the area of arsenic management. While sulphidization has been used in the past for arsenic removal, enhancing the process and the stability of the final by-product of treatment will enable mining companies to process arsenic-bearing ores for extraction of valuable metals in an environmentally safer manner. Given the importance of the minerals sector to the Canadian economy, the implementation of the proposed process will bring enormous economic, social and environmental benefits to Canada. The proposed project will train 1 postdoctoral fellow and 2 undergraduate research assistants.
由于高品位矿石的枯竭,金属的生产需要加工砷含量越来越高的低品位矿石。加工这类原材料会将砷引入冶金回路,导致产生含有有毒和致癌的砷的废物流。我们与BQE Water(一家在受矿山影响的水和工艺溶液处理及管理方面拥有专业知识的水处理服务供应商)合作,建议加强基于硫化物的沉淀工艺,以高砷含量的三硫化砷形式去除并稳定砷。与现有的去除方法相比,由于砷含量高,这种硫化过程将产生最少量的含砷废物副产物,其可高达60%,比现有方法产生的5-30%含量有大幅增加。然而,三硫化二砷的稳定性是一个主要问题,因为它的溶解度和对大气和细菌氧化的敏感性。因此,拟议项目将解决的关键技术挑战是评估和制定一项战略,以提高三硫化二砷在各种条件下的稳定性,特别是在与实地安全储存有关的条件下。强化硫化工艺与BQE Water的战略技术开发非常一致。所产生的新知识将加强现有的专门知识,并促进其在砷管理领域的业务。虽然过去曾采用硫化法去除砷,但加强这一工艺和处理的最终副产品的稳定性,将使采矿公司能够以环境上更安全的方式加工含砷矿石,以提取有价值的金属。鉴于矿产部门对加拿大经济的重要性,实施拟议的进程将给加拿大带来巨大的经济、社会和环境利益。本项目拟培养博士后1名,本科生研究助理2名。
