在铁矿分析中,往往需要对一个试样测定全铁和可溶铁。对此,各实验室的分析方法大同小异,一般是取两分试样分别加以测定,就能获得满意的结果。但是对于一些易溶于盐酸的铁矿石,如赤铁矿等,实际上其中的可溶铁量等于或是略小于全铁量,而在常规分析中,由于不可避免的测定误差,使其结果出现可溶铁小于、等于或大于全铁三种情况。第一、二两种情况,其结果是合理的;第三种情况中,尽管其差是在允许分析误差范围之内而且可能很小,但从理论上说是不合理的.地质人员对此类结果提出的责难是无可非议的。
In iron ore analysis, it is often necessary to determine total iron and soluble iron on a sample. In this regard, the analysis of the laboratory methods are similar, generally take two points were measured separately, you can get satisfactory results. However, for some easily soluble in hydrochloric acid iron ore, such as hematite, in which the soluble iron is equal to or slightly less than the total iron, and in routine analysis, due to inevitable determination of error, make it The results appear less soluble iron, iron equal to or greater than three cases. The first and second cases, the result is reasonable; the third case, although the difference is within the allowable analytical error range and may be small, but in theory it is unreasonable. Geological staff on this The blame for the class result is beyond reproach.
