Processing Spodumene by Froth Flotation for Lithium

2016-5-9  Grinding and Classification. The Steel Head Rod Mill has proven extremely satisfactory for grinding such pegmatitic mineral as feldspar and spodumene. The grinding circuit should have a controlled feed rate which is accomplished with a

Effects of grinding environment and lattice impurities

2019-7-1  The effect of grinding on the spodumene flotation was investigated. The flotation response of spodumene ground by different mills was different, due to the variation of metal ions on spodumene surfaces caused by grinding environments and/or impurities. The samples were subjected to acid pickling treatment to remove most of the metal ions from

Mining and Concentrating Spodumene the Black Hills,

2016-5-24  The spodumene readily breaks free of the matrix on crushing and grinding, the fine crystal fragments tending to break into long needlelike splinters or flat rectangular particles. Under lOOX magnifica- tion many of these particles show parallel, longi- tudinal traces of altered material. In hand speci- mens, a claylike coating may be scraped from cleav- age surfaces in all but the freshest and

Effects and Mechanism of Different Grinding Media

(2) The adsorption energy between spodumene and sodium oleate was −54.84 kJ/mol before grinding, and −57.12 kJ/mol after grinding, the change value of adsorption energy was −2.28 kJ/mol. The adsorption energy was weakened after iron media grinding, which strengthened the interaction between collectors and spodumene.

Effects and Mechanism of Different Grinding Media

With sodium oleate as a collector, within the same pH environment, the recovery of beryl and spodumene under zircon ball wet-grinding is lower than those under iron wet-grinding. We observed formation of iron-hydroxyl complexes on the mineral surface after iron ball grinding, which are significant influence on the flotation behavior of silicate minerals.

Phase transformation mechanism of spodumene

2019-8-15  Our synchrotron XRD experiment demonstrates that, γ-spodumene initially forms via the re-crystallisation of the amorphous spodumene resulting from grinding of the concentrate. Further grinding to a smaller grain size clearly enhances the formation of γ-spodumene during heating, as evidenced by the ex-situ XRD spectrum illustrated in Fig. 4.

β-spodumene. The α-spodumene is virtually refractory to hot acids. As a result of the phase transformation, the spodumene crystal structure expands by about 30% and becomes amenable to hot sulphuric acid attack. Due to this expansion, the specific gravity of the spodumene decreases from 3.1 g/cm3 (natural α-spodumene) to around 2.4 g/

In the majority of cases, a grind size (K80) of approximately 200 microns is sufficient for flotation. After primary grinding, mica, if present in an appreciable amount, should be floated to minimize interference with spodumene flotation.
