  • Investigation of quartz flotation from decarburized vanadium bearing

    Abstract: Ether diamine (Fm 28352L) was used as a collector for flotation of quartz. It allows flotation of quartz from mica and calcite. The adsorption mechanism of Fm 28352L on quartz was investigated by flotation tests, zetapotential measurements and infrared (FTIR) spectra measurements. Results show that.
