1. A method for predicting the presence of rare earth elements (REEs) in a feedstock, comprising:
measuring a feedstock sample using a spectrum analyzer to generate measurements of elements of interest with a lower atomic weight than REEs;
correlating the measurements with a model; and
predicting presence of one or more REEs based at least in part on the correlation.
