探讨了铅阳极泥中金、银、铜、锑、铋等金属回收方法与指标以及砷的污染防治措施。
Processes for extracting metals from the slurry and recovery rates of them, such as gold, silver, copper, antimony and bismuth, and measures of controlling arsenic pollution are discussed.
结果证明采用水蒸气焙烧的方法可以较为彻底地脱去砷和锑，达到冶炼的要求，并且和传统的预处理措施相比，成本低，污染程度轻。
The results shows this method can be effectively used for remove As and Sb from the concentrate to meet the requirement of smelting and has the advantages of low cost and low environmental pollution.
由于自然过程及人类活动的影响，锑及其化合物在环境中普遍存在，环境中锑的污染也日益严重。
Antimony and its compounds are widely used in various manufacturing and semiconducting industries. It presents in the environment as a result of natural process and human activities.
该工艺锑的脱除率高，流程短，低能耗和无污染，可直接得到贵铅。
The test results prove that this technology can produce precious lead directly with no pollution, lower energy consumption. short process flow and high removing rate of antimony.
