氧化铝生产的赤泥分离是一个非常重要的工序,而且一直是生产中的薄弱环节。郑州铝厂利用汲县化工厂的产品 A-1000~#絮凝剂为原料,提出了专门的处理技术,使其能有效地应用于拜尔法赤泥,特别是烧结法赤泥的分离过程,首次在工业规模上得到验证。工业实际应用证明,有关的各项技术指标都很良好,为生产带来明显的效益:可以实现烧结法赤泥的纯沉降分离,去掉消耗巨大、劳动繁重的真空过滤系统;产能提高;劳动条件和环境改善;应用
Red mud separation from alumina production is a very important process and has been a weak link in production. Zhengzhou Aluminum Plant uses the product A-1000 ~ # of Jixian Chemical Plant as raw material, puts forward a special treatment technology that can be effectively applied to the separation of Bayer process red mud, especially sintered red mud, For the first time in the industrial scale has been verified. Industrial practical application shows that the relevant technical indicators are very good, bringing significant benefits for the production: the pure sedimentation separation of sintered red mud can be achieved, eliminating the heavy consumption of labor and heavy vacuum filtration system; capacity increase; working conditions And environmental improvement; application
