这是一项廿年前我国就试验成功而应用于除铜镉的技术。意大利萨米公司不仅把它应用于除铜镉,也应用于除钴。他们的实践表明,这项技术不仅可以减少溶液净化设备的尺寸,也可减少其数量。在投资及操作费用上大为降低,特别在蒸汽、锌粉及人力消耗上都可大幅度下降。本文将对采用三氧化二锑净化时,对传统工艺与沸腾反应器进行全面的技术经济比较。 This is a technology that was applied to copper and cadmium removal successfully in China twenty years ago. Sami, Italy, not only used it in addition to copper and cadmium, also used in addition to cobalt. Their practice shows that this technology can not only reduce the size of the solution purification equipment, but also reduce the number. In the investment and operating costs greatly reduced, especially in steam, zinc and human consumption can be significantly reduced. This article will be on the use of antimony trioxide purification, the traditional process and the boiling reactor for a full technical and economic comparison.
