Effects of high Mg2+ concentration on KCl flotation:

2007-6-1  The flotation research indicated that KCl flotation only occurred when the amine collectors R 12 NH 3 Cl(s) (dodecylamine hydrochloride) reached solubility saturation and precipitated from solution. It has been reported by Laskowski et al. (1988) , that these collectors are positively charged at natural pH.

Quantitative determination of cavitation formation

2020-5-1  The sensitivity analysis results show that granule size is the main contributing parameter for granule flotation over substrate concentration, which supported the fact that most of researchers try to control granules size to mitigate granular sludge flotation (Chen et al., 2010; Wang et al., 2014). The possible reason is that the decrease in the granule size could favor mass transfer to support cell

Flotation concentration of a xenotime pre-concentrate ...

Abstract The world market for rare-earths elements is increasing due to the development of new products and applications, resulting in the need for technology to treat deposits having highly complex mineralogy, such as that of Pitinga, AM, Brazil, with estimated reserves of 146,960 t of rare-earths oxides (REO), including Y2O3. Mineralogically the mine of Pitinga is very rich. The initial and ...

Quantitative determination of cavitation formation

2020-5-1  The optimum granule diameter to avoid flotation but with excellent settling performance was identified around 2.5 mm. Additionally, the granule size is more sensitivity to flotation than substrate concentration. Hence, controlling the size of granules is more important to alleviate granule flotation in Anammox reactors’ operation.

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 mafic enclaves
