  • 铜是能量转换过程必不可少的金属,主要通过湿法和火法从黄铜矿中获得。该过程产生的风险和有害影响引起了人们对环境和人类安全的广泛关注,凸显了对更为有效且环保的湿法冶金方法的需求。本综述着重介绍了目前处理复杂黄铜矿的有效工艺,如氧化浸出、生物浸出和加压浸出。氧化浸出浸出条件温和,且氧化剂的引入具备一定优势。生物浸出是一种非侵蚀性的方法,铜的提取效率逐渐提高,并已探索使用铜的一次资源和二次资源。加压浸出高效、选择性强,随着研究的不断深入其在商业上更具竞争力。本文也为进一步推进该领域的研究提供了重要数据。

    Hydrometallurgical processing of chalcopyrite: A review of leaching techniques

    + Author Affiliations
    • Copper, an essential metal for the energy transition, is primarily obtained from chalcopyrite through hydrometallurgical and pyrometallurgical methods. The risks and harmful impacts of these processes pose significant concerns for environmental and human safety, highlighting the need for more efficient and eco-friendly hydrometallurgical methods. This review article emphasizes current processes such as oxidative leaching, bioleaching, and pressure leaching that have demonstrated efficiency in overcoming the complicated chalcopyrite network. Oxidative leaching operates under benign conditions within the leaching media; nevertheless, the introduction of oxidizing agents provides benefits and advantages. Bioleaching, a non-aggressive method, has shown a gradual increase in copper extraction efficiency and has been explored using both primary and secondary sources. Pressure leaching, known for its effectiveness and selectivity in copper extraction, is becoming commercially more viable with increased research investments. This research also provides important data for advancing future research in the field.
