increased selectivity between hematite and ferromagnesian silicates. Application of a mixture of alkyletherdiamine and primary monoamine at 2:1 ratio with reagent dosage at 110 g/t allowed formation of a stable adsorption layer on the quartz surface and on the non-homogeneous surface of Fe-silicates, and ensured their rather complete flotation.

Selective flotation of silicates and Ca-bearing minerals ...

Flotation of pure minerals was performed to characterize the conditions for separation of silicates (palygorskite, quartz, orthoclase, albite, biotite, and muscovite) and Ca-bearing minerals (calcite, apatite and gypsum). These minerals constitute a large portion of gangue in some low-grade ores of industrial and rare metals (such as rare earth ...

2012-10-1 · Although flotation has been applied to separate silicates from Ca-bearing minerals using amine collectors, there is very scanty information on selective separation of palygorskite from silicates. Amines are known to be effective flotation reagents for silicates in all pH range ( Sekulić et al., 2004 , Fuerstenau and Pradip, 2005 ).

Sodium Silicate in Phosphate Flotation

2021-3-8 · Some factors adversely affect the efficiency of anionic flotation of phosphate in the absence of sodium silicate, thereby decreasing the concentrate grade. Impurities originally present on the quartz surface might be responsible for this adverse effect, but the precipitates heterocoagulated onto the surface of quartz also appeared to play a role. Dissolved ions, especially Ca++, can be present ...
