Laboratory Testing of Scheelite Flotation from Raw Ore in ...

Tungsten is an essential metal for the manufacture of special alloys, which is in constant demand due to the development of the industry. The recovery of scheelite from undeveloped tungsten ore in South Korea was investigated to improve the flotation performance for high grade and recovery of concentrate. To investigate the interaction between the flotation reagents and the minerals, the ...

Sulfides flotation is a process to remove sulfides mineral, such as molybdenum (molybdenite, MoS 2) in ores before the scheelite flotation process, because they adversely affect the grade and recovery of concentrate in scheelite flotation. In this process, 150 g/t of KAX and 50 g/t of MIBC were used as a collector and frother, respectively.

Previous studies have proved that the lead complexes of benzohydroxamic acid (Pb–BHA) are effective collectors of scheelite flotations; however, the separation of scheelite from calcite needs depressants with high selectivity. In this study, we reported a novel depressant for calcite minerals, and Pb–BHA served as the collector of scheelite. The flotation behavior of polyaspartic ...
