The LF slag composition was analyzed in X-ray fluorescence (XRF), and the average value of different heats is reported. Table 3 shows the composition of LF slag (collected after the LF treatment process) and fluorspar. It is to be noted that the replacement of fluorspar is to be done in the Si-killed steelmaking process route.

Therefore, in the process of sorting, it is necessary to first break the joint body of fluorite and waste rock, and then use the method of re-selection to discard the waste rock that is obviously different from the fluorite essence. In this way, high-quality fluorspar crystal blocks can be obtained, which can be used as fluorspar for metallurgy.
