In view of the shortcomings of traditional copper ore detection methods, this paper proposes a copper content detection model based on spectral data and VTELM, and validates the model with collected copper ore samples. First, we collected 241 copper ore samples, used chemical analysis to detect the copper ore to obtain the accurate copper ...
