Mineralogy and flotation of rare-earth-bearing barium ...

This “mineral” was identified as rare-earth-bearing barium fluorophlogopite (REBF). Flotation experiments were conducted to investigate the flotation behaviors of the REBF. Experimental results show that the REBF can be collected by using dodecylammonium acetate, sodium oleate or a combination of both in an appropriate proportion and sequence.

Process mineralogy of Dalucao rare earth ore and design

2020-6-28 · The rare earth minerals have a small monocrystal grain size and are interlocked with other minerals such as barite, fluorite, celestite and calcite, eventually leading to a serious encapsulation phenomenon [13,14,15]. During flotation, the grinding fineness seriously affected the grade and recovery rate of the rare earth ore concentrates.

RESEARCH FOCUS: Flotation of magmatic minerals |

2015-7-1 · The “flotation” of magnetite has been suggested for other magmatic systems. A single bubble observed in the Bishop Tuff was coated in small magnetite crystals (Gualda and Anderson, 2007), interpreted as reflecting heterogeneous nucleation of bubbles on magnetite, as commonly observed in experiments (Gardner and Denis, 2004).Bubbles and magnetites were coupled in

The flotation separation of apatite from calcite is gordian due to the similar surface properties and calcium active sites, which make a poor selectivity in traditional fatty acid system. Pb-BHA coordination collector present great selectivity, and surface transformation by fluoride ions plays an important role in the flotation separation of salt minerals.
