Calcite is a semi-soluble mineral that can be considered one of the main problematic
gangue phases for several different types of valuable sulfides and oxides. Since froth …

Froth flotation has been widely used in upgrading iron ores. Iron ore flotation can be
performed in two technical routes: direct flotation of iron oxides and reverse flotation of …

In flotation, the application of some flotation reagents may cause serious water pollution and
damage the ecological environment and human health. Large consumption of flotation …

The effects of Ca2+, Mg2+, Al3+, and Fe3+ on the flotation behaviors of apatite, dolomite
and quartz were investigated through a micro-flotation test, and the influence of calcium ions …

Abstract Poly (sodium 4-styrene sulfonate) was tested as a novel and efficient depressant for
the selective flotation of apatite and dolomite in this work. The separation performances …

The effective separation of apatite and dolomite is always the focus of phosphate ore
flotation research. The effect of citric acid (CA) on the flotation reaction of apatite and …

Apatites of different geological origins exhibit different floatabilities under the direct flotation
process. However, the floatability of apatite from different geological origins under reverse …

Abstract In this study, 2-phosphonobutane-1, 2, 4-tricarboxylic acid (PBTCA) was introduced
as a depressant for the flotation separation of apatite from calcite. The micro-flotation test …

Fluorapatite flotation is influenced by the dissolved lattice metal ions. Al 3+ and Mg 2+ from
the associating gangue minerals influence the adsorption of collector molecules onto the …

Phosphate ores upgraded by flotation are widely used as vital raw materials for the
sustainable production of phosphate fertilizers to maintain the food supply. High-grade …
