    A new collector for rare earth mineral flotation

    A new collector for bastnaesite flotation - modified hydroxamic acid (MOHA) has been developed through several years oratory research. The experimental results of flotation of pure bastnaesite mineral and rare earth ores, and the application experience in flotation plants showed that MOHA is an efficient collector for bastnaesite flotation.
