The invention discloses a method for determining the content of pulverized coal, coke and iron-containing charge in blast furnace dust, which comprises the following steps: 1) determining the true density of materials; 2) preparing a separating medium; 3) carrying out centrifugal separation on the furnace dust; 4) measuring and calculating the weight percentage content of settled coal and settledcoke; 5) calculating the weight percentage content of coal and coke in the furnace dust; and 6) measuring and calculating the composition of the iron-containing charge in the furnace dust. Compared with the prior art, the method has the following advantages and positive effects: the creativity is novel, the method adopts the physical separation method of centrifugal sedimentation to measure and calculate the content of the coal, the coke and the iron-containing charge in the blast furnace dust by utilizing the properties that the particle size ranges of the components are close, but the true densities of the components are greatly different; and the operation is simple, the test accuracy is high, the determination method is less affected by human factors, and the accuracy of the method ishigher than that of the coal rock microscopic analysis method.
