DOI: 10.1016/j.mineng.2021.107003
Abstract: Abstract Compared with copper and lead oxide, zinc oxide often requires activation for it to be effectively enriched during sulfidization–xanthate flotation. We investigated the effect of Pb ion pre-modification on the surface structure, sulfide layer… read more here.

DOI: 10.3390/min9040204
Abstract: In this work, a sulfidization mechanism of malachite was confirmed based on the depth profile product, principal component, and depth profile curve analyses of time-of-flight secondary ion mass spectrometry (TOF-SIMS). The results showed that Cu/S… read more here.
