    • The present disclosure relates to systems and methods by which lead from spent lead-acid batteries may be extracted, purified, and used in the production of new lead-acid batteries. Such a system may include a first phase separation device (76) configured to receive the first mixture from the basic lead stream digestion device (192), isolate a liquid component (196) from one or more insoluble components (78) of the first mixture, and output the liquid component (196). The system also includes a lead salt precipitation device (200) configured to receive and mix the liquid component and a carboxylate source (201) to form a second mixture including a lead salt precipitate and output the second mixture. The system further includes a second phase separation device (92) configured to receive the second mixture from the lead salt precipitation device (200), isolate the liquid component (96) from the lead salt precipitate (94) of the second mixture, and output the lead salt precipitate, which may later be converted into leady oxide particles (100).
    • 本公开涉及可以提取,纯化和用于生产新铅酸电池的废铅酸电池的铅的系统和方法。 这样的系统可以包括被配置为从碱性引导流消解装置(192)接收第一混合物的第一相分离装置(76),将液体组分(196)与第一混合物的一种或多种不溶性组分(78) ,并输出液体组分(196)。 该系统还包括被配置为接收和混合液体组分和羧酸盐源(201)以形成包含铅盐沉淀物的第二混合物并输出第二混合物的铅盐析出装置(200)。 该系统还包括第二相分离装置(92),其配置为从铅盐沉淀装置(200)接收第二混合物,将液体组分(96)与第二混合物的铅盐沉淀物(94)隔离,并输出 铅盐沉淀物,其可以随后转化成铅氧化物颗粒(100)。
