摘要
经反复实践,将铜矿石样品的浸取滤液水分蒸发干后,采用盐酸溶解,稀释到一定体积比例,就可以使用原子吸收光谱法来准确地测定铜矿石物相分析中的铜。此方法较以往的化学法测定相比,不仅大大缩短了工艺流程,且干扰离子少,测试灵敏度高。
According to repeat practice, after the evaporation and dry of filtered immersion liquid of Cu ore sample, it is resolved with hydrochloric acid, diluted to a certain volume ratio, then Cu can be tested accurately with atomic absorption spectrography in phase analysis of Cu ore. In comparison to the past chemical analysis, this method not only shortens evidently the working flow chart but also decreases the disturbance ion, testing sensitivity high, particularly suitable to the phase analysis of low grade Cu ore.
