一、锌精馏技术沿革该厂于1963年引进美国新泽西锌公司专利,建两座铅塔和一座镉塔,组成典型的三塔型塔组,以精炼其竖罐所产粗锌,生产能力为1500吨精锌/月。 1967年建一座处理无镉锌的铅塔,生产低成本的精锌,其生产能力为750吨精锌/月。至此,该厂总生产能力达2250吨精锌/月。 1969年利用处理无镉锌的铅塔产出的纯
First, the zinc distillation technology evolution The plant in 1963 the introduction of the United States New Jersey zinc company patents, built two lead towers and a cadmium tower, composed of a typical three tower tower group, to refine its vertical tank crude zinc production capacity 1500 tons of refined zinc / month. In 1967 a cadmium-free lead-zinc tower was built to produce low-cost refined zinc with a production capacity of 750 tons of refined zinc per month. So far, the plant’s total production capacity of 2250 tons of refined zinc / month. In 1969 the use of lead-free zinc cadmium treatment output of pure
