Figure 10. Comparison of the effect of collectors on the recovery of rare earth minerals by flotation. The comparison is between SHA and H2O5 from three sets of experimental designs. At similar dosages, H2O5 had a higher recovery than SHA. See Table 5 and associated discussions for statistical analyses. SHA: Salicylhydroxamic acid; H2O5: N,3-dihydroxy-2-naphthamide.
