    摘要: The present disclosure relates to a modular system for beneficiating a ferrous ore, comprising: a primary crushing module including a primary crusher for receiving and crushing the ferrous ore into a ferrous aggregate, a first grinding and classification module for receiving the ferrous aggregate, including a first grinding mill for grinding the ferrous aggregate, and first classification equipment for classifying the resultant product into at least a first fine aggregate stream, a first separation module including first separation equipment for receiving and separating the first fine aggregate stream into at least a first ferrous aggregate stream, a second grinding and classification module for receiving the first ferrous aggregate stream, including a second grinding mill, and second classification equipment for classifying the resultant product into at least a second fine aggregate stream, and a second separation module including second separation equipment for receiving and separating the second fine aggregate stream into at least a concentrated ferrous aggregate stream. The disclosure further relates to a method of beneficiating a ferrous ore with said system, and a grinding and classification module.

    摘要: 本发明涉及选矿技术领域,提供了有色金属矿预选抛废方法。本发明首先通过破碎和第一筛分分级得到第一粗矿、第一细矿和第一合格矿,第一粗矿通过智能矿石分选进行预选抛废,去除其中的脉石尾矿,剩余的第一粗精矿破碎后进行第二筛分分级,得到第二细矿和第二合格矿,最后将第一细矿和第二细矿通过重介质选矿进行预选抛废,进一步去除其中的脉石尾矿,重介质选矿所得精矿为合格矿。此外,本发明还可以单独使用智能矿石分选或重介质分选进行预选抛废,工艺步骤更加简单。本发明提供的方法自动化程度高,选矿精确性高,有色金属矿的回收率高,抛废率高,且对矿石种类没有限制,适用范围广。

    摘要: É descrito um processo para a recuperação de alumínio, ou processo de reciclagem, o qual se baseia em separar o alumínio contido em embalagens assépticas cartonadas (1), embalagens flexíveis (2) e pó de ligas de alumínio (3) residual utilizado em manufatura aditiva, através da dissolução seletiva do alumínio em solução conhecida como licor Bayer e/ou soda caustica, tendo como produtos aluminato de sódio (líquido) e gás hidrogênio (H 2 , gasoso). Ambos produtos podem ser utilizados numa refinaria de alumina, o aluminato de sódio é utilizado para a produção de hidróxido de alumínio e o hidrogênio pode ser utilizado com o combustível de caldeiras, fornos ou similares.
