不用汞盐测定铁矿石中全铁的方法试验,近年来在各研究单位和生产厂矿,均极重视。试验研究的方法较多,有些方法已用于生产,收到了良好的效果。我们在吸取弟兄单位宝贵经验的基础上,结合我矿的实际情况,取用硅钼黄作还原指示剂不用汞盐测定铁矿石中全铁的方法,作了一些试验,并于七七年元旦用于日常化验工作。至10月上旬,我们
No mercury salt determination of total iron in iron ore test method, in recent years in all research units and factories and mines, are extremely valued. There are many methods of experimental research and some methods have been used in production and have received good results. Based on the valuable experience of our brother unit and based on the actual situation of our mine, we took some tests on the method of using silicon molybdenum yellow as a reduction indicator and determination of total iron in iron ore without mercury salt. In routine laboratory work. To early October, we
