清洁高效的提取冶金——矿浆电解

摘要:

环境污染和能源短缺是重有色金属冶炼的两大障碍。在对重有色金属湿法冶金存在主要问题进行分析的基础上研究成功的矿浆电解新技术,是一种清洁、高效的提取冶金。它具有流程短、能耗低、金属分离好和环境污染少等特点。矿浆电解的显著特点是充分利用了电积过程的阳极反应来浸出矿石,工艺能耗大大降低;在电解槽中硫化物转化为元素硫,而不产生硫酸,有利于环境保护。文章描述了国内外矿浆电解技术的发展过程及我国建立的世界上第一个矿浆电解工业生产厂的概况,指出我国在该领域处于世界领先地位和矿浆电解技术具有很好的前景。

摘要: Currently, increasing amounts of end-of-life (EoL) electronic products are being generated due to their reduced life spans and the unavailability of suitable recycling technologies. In particular, waste printed circuit boards (PCBs) have become of global concern with regard to environmental issues because of their high metal and toxic material contents, which are pollutants. There are many environmental threats owed to the disposal of electronic waste; off-gasses, such as dioxins, furans, polybrominated organic pollutants, and polycyclic aromatic hydrocarbons, can be generated during thermal treatments, which can cause serious health problems if effective off-gas cleaning systems are not developed and improved. Moreover, heavy metals will dissolve, and release into the ground water from the landfill sites. Such waste PCBs contain precious metals which are of monetary value. Therefore, it is beneficial to recover the metal content and protect the environment from pollution. Hydrometallurgy is a successful technique used worldwide for the recovery of precious metals (especially gold and silver) from ores, concentrates, and waste materials. It is generally preferred over other methods because it can offer high recovery rates at a relatively low cost. This article reviews the recent trends and developments with regard to the recycling of precious metals from waste PCBs through hydrometallurgical techniques, such as leaching and recovery.

摘要:

硫酸镍作为镍产业链中至关重要的一环,是支撑我国新能源汽车动力电池、电镀等领域发展的核心原料,其原料生产、冶炼加工、回收利用等技术发展方向和行业发展趋势都备受关注。本文梳理了我国硫酸镍产业的发展动态,总结了我国硫酸镍产量、技术等发展现状,分析了我国硫酸镍产业面临的主要问题及其发展趋势,认为我国硫酸镍发展面临的问题主要来自于原料供应紧张、碳排放强度高、回收体系不完善等。在此基础上,提出了面向2035 年的发展思路和发展目标,从注重供应体系的建立,促进多样化原料供应;促进技术创新,降低生产成本减少供应压力;加快发展再生镍行业,提高再生镍用量;加快推进我国企业国际化、产业一体化进程,提升核心竞争力等方面提出对策建议。期望以需求为导向,通过硫酸镍生产技术、原料供应、回收利用等体系的完善,促进我国硫酸镍产业持续健康发展。
