The invention discloses a detection method of uniformity of sinter. The detection method comprises the steps of firstly, utilizing an optical microscope to observe and record positions of different minerals in the sinter, and then drawing a distribution map of minerals in the sinter; next, calculating uniformity of distribution of main minerals in the sinter according to the distribution condition of main minerals in different areas in the distribution map; next, calculating a uniformity quantitative of the sinter according to the uniformity of the distribution of the main minerals in the sinter; then, utilizing the uniformity quantitative of the sinter to evaluate the uniformity of the sinter. According to the detection method of uniformity of the sinter, by drawing the distribution map of the minerals in the sinter, the uniformity quantitative in the sinter is gradually calculated, the uniformity index of the sinter is accurately quantified by utilizing the uniformity of the sinter, and the uniformity of the sinter can be visually shown.
