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

, 2022
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 ...
