The invention, which belongs to the technical field of mineral identification, proposes a mineral identification method based on reflection spectrum. The method comprises the following steps: S1, carrying out data measurement; to be specific, measuring a plurality of sampling points in a sample by using a spectrograph to obtain a measurement value; S2, carrying out data processing; to be specific,acquiring a spectral waveform of each sampling point based on the measurement value of each sampling point in the S1, carrying out splicing correction, and then carrying out equalization to obtain aspectral waveform of the sample; S3, carrying out mineral identification; to be specific, carrying out calculation on the spectral waveform data of the sample in the S2 to obtain the position of a characteristic valley, carrying out standard matching on typical minerals in a spectrum database based on the wavelength of the characteristic valley to obtain a matched mineral, and then comparing the spectral waveform of the matched mineral with the spectral waveform of the sample to obtain minerals that may exist in the sample; and S4, carrying out data calculation; to be specific, carrying out fitting calculation on the minerals that may exist in the sample to obtain mineral compositions in the sample and relative content of all compositions. Therefore, problems of low recognition precision and long recognition time in the prior art are solved.
