一、微量粒度分析法的基础微量粒度分析法的基本点可分两个方面。第一是认为容器内的矿浆经过充分搅拌后是均匀的,如图1杯内的矿浆已经充分的搅拌(静置时间为零),是均匀的。把矿浆分成a_1、a_2、a_3……a_n等相同厚度的若干小层,它们在粒度组成及化学组成等性质方面是完全相等的,即是: a_1=a_2=a_3=……=a_n若取出其中任意一层都能代表整个矿浆的特性,就是各层内部处处也是均匀的,任意取出其中一点都能代表这一层,而它也能代表整个矿浆。这一点已由试验证实。用此法当沉降时间为零,吸出之物料的分析品 First, the basic principle of trace particle size analysis Traceability analysis of the basic points can be divided into two aspects. The first is that the pulp in the container after mixing is uniform, as shown in Figure 1 cup slurry has been fully stirred (static time zero), is uniform. The ore is divided into several small layers of the same thickness such as a_1, a_2, a_3 ...... a_n, which are completely equal in terms of particle size composition and chemical composition, that is: a_1 = a_2 = a_3 = ...... = a_n Any layer can represent the characteristics of the entire pulp, that is, the interior of each layer is also uniform everywhere, any point out of any one can represent this layer, and it can represent the entire pulp. This has been confirmed by the test. Use this method when the settlement time is zero, sucked out of the material of the analytical product
