摘要
自20世纪70年代以来,由于离子交换技术的应用,我国钨冶炼技术研究方面取得了显著的进步,钨产品质量大大提高。在仲钨酸铵生产过程中,锡的存在对产品质量有很大影响,需要预先去除。近年来,我国除锡方法的研究发展很快,出现了一些新的方法和技术。结合我国钨冶炼工艺中除锡研究状况,分析了我国除锡技术的发展方向。
Since 1970s,Chinese tungsten metallurgy has made remarkable progress and product quality ranked high because of application of ion-exchange technology.Ammonium paratungstate quality is (affected) by stannum in solution. In recent years, some new methods about removing of stannum from tungsten are put forward. According to this status, developing trend of W-Sn separation technology in our country is analyzed.
