·separation of feldspar from quartz The selectivity achieved in feldspar quartz separation is discussed terms of collector chemistry and liberation size of the constituent minerals Experimental Mineralogy and characterization of ore The representative ore sample assays % Si0 2 % A1 20 3 % K 20 % Na20 % Ti0 2 and 0
·The study s findings lead to a reduction in iron content in feldspar concentrate to % Fe2O3 with % K2O content whereas separate concentrations of oxide concentrate with 6 53% Fe2O3
·Topaz granites are alkali feldspar granites containing albite quartz K feldspar lithium mica and topaz which are characterized by their an extreme enrichment in F upto 4 wt % enrichment in
·Quartz and feldspar cannot be efficiently separated using physical methods owing to their similar physicochemical properties In recent years flotation has emerged as the most effective method for separating feldspar and quartz Larsen and Kleiv 2016 Shu et al 2020 Xu et al 2020 Traditional flotation methods to separate these two minerals generally include acid
·The physical and chemical properties of feldspar and quartz are highly similar thus they cannot be easily separated effectively In this work the flotation separation of feldspar from quartz using sodium fluosilicate Na2SiF6; SF as a selective depressant was investigated Moreover the influence mechanism of SF on the selective flotation separation of feldspar and
·Reports show that the lithium ore from Jiajika contains % by weight of spodumene % mica % feldspar and % quartz Xu et al 2016c Generally spodumene concentrate is the desired product in industrial beneficiation
·% which also falls below the minimum standards for quartz products The results of the XRD analysis in Figure 1 indicate that the main mineral components of the original ore are quartz and potassium feldspar with a quartz content of about 45% a potassium feldspar content of about 25% a mica content of about 15% and a kaolinite content of
·This study designed a mixed surfactant with solubilization behavior for selective flotation separation of feldspar and quartz By optimizing the compounding ratio and dosage of reagents the optimal mixed surfactants dodecylamine DDA sodium dodecyl sulfate SDS and dodecane with the concentrations of and mmol/L used in flotation separation of
·Unfortunately most of feldspar resources in China reportedly are characterized with fine liberation size consisting quartz mica and iron minerals Hu et al 2005 Zhou et al 2013 Owing to the lack of advanced processing and mechanism to extract feldspar from these minerals the production of feldspar with high quality is relative low
