Enhanced flotation of Pb(II)-activated wolframite using a novel

The flotation enrichment of fine-particle wolframite played a crucial role in production of strategic key metal tungsten. In this paper, N-[(3-hydroxyamino)-propoxy]-N-hexyl dithiocarbamate (HAHD) was designed to strengthen the flotation recovery of wolframite.The in situ AFM images clearly exhibited that the pre-activation of Conclusions. In this study, DOPA was designed and first applied as a flotation collector to selectively separate wolframite from calcium bearing minerals (fluorite and calcite). The chemical properties of DOPA from the perspective of molecular level were comprehensively investigated by computational calculations.New insights into separating wolframite from calcium bearing minerals

Study on the Activation of Scheelite and Wolframite by Lead

The activation of scheelite and wolframite by lead nitrate with benzohydroxamic acid (BHA) as collector was investigated by means of micro flotation test, zeta potential measurement, X-ray photoelectron spectroscopy (XPS) analyses and density functional theory (DFT) calculation. The flotation results confirmed that the addition of From Figure 2, the recoveries of scheelite and wolframite increase from 28.8% to 95.5% and 15.5% to 89.5% with the increase of BHA dosages from 50 to 300 mg/L in the presence of lead nitrate, respectively. But without the addition of Pb (NO 3) 2, their recoveries by BHA hardly increase, both lower than 20%.Study on the Activation of Scheelite and Wolframite by Lead
