Abstract

The invention provides a method for separation and content determination of clay particles, and relates to the technical field of particle number measurement. The method for separation and content determination of clay particles comprises the following steps of: determining the content X1 of a main mineral phase and the content X2 of a secondary mineral phase in machine-made sandstone powder; dissolving machine-made sandstone powder in the solution to form turbid liquid, and dissolving clay minerals; separating out a solution containing clay minerals by adopting a natural sedimentation method;drying the separated solution; repeating the separation steps for multiple times, and collecting particles separated for multiple times; and quantitatively analyzing the content x2 of the clay minerals, so as to obtain the content (X2x2/100)% of the clay minerals in the machine-made sandstone powder. According to the method, particles smaller than 5 micrometers can be extracted through adopting anatural sedimentation method, meanwhile, the content of the clay minerals processed through a quantitative analysis method is measured, the accuracy degree can reach 80%-90%, and therefore the content of the clay particles in the machine-made sand can be separated and measured more accurately, and misjudgment is not likely to be caused.

Description

technical field [0001] The invention relates to the technical field of particle number measurement, in particular to a method for separation and content determination of clay particles. Background technique [0002] In the prior art, in order to separate and measure the content of clay particles in the machine-made gravel powder, the sand equivalent test method or the methylene blue value test method is usually used. Among them, the sand equivalent test method is used to determine the content of cohesive soil or impurities contained in various fine aggregates such as natural sand, artificial sand, and stone chips, so as to evaluate the cleanliness of the aggregate. The methylene blue value test method is used to determine whether there is expandable clay mineral in fine aggregate, fine powder, ore powder and to determine the overall index of its content. [0003] However, neither the sand equivalent test method nor the methylene blue value test method can effectively separa...
