福建某高岭土伴生石英提纯试验研究OA

Taking quartz associated with a certain kaolin in Fujian as the research object,X-ray diffraction(XRD)and X-ray fluorescence spectroscopy(XRF)were used to detect the phase composition and chemical composition of the ore sample.Then,scrubbing,magnetic separation,flotation,and grading sorting condition tests were carried out sequentially.The results showed that the mass fraction of SiO2 in the sample was relatively low,at 85.16％;Quartz mainly exists in two forms,one is a monomer,and the other exists in rock debris,coexisting with feldspar,mica,and other minerals;The flotation test results show that the amount of collector and flotation concentration have a signifi-cant impact on reducing the content of Al2O3;The grading sorting test revealed that under the same process condi-tions,the content of impurity in the quartz concentrate of +0.6 mm particle size is much lower than that in the quartz concentrate of-0.6+0.1 mm particle size;The mass fraction of impurity Al2O3 in the final obtained concentrate is 2 918.68 μg/g,and the mass fraction of Fe2O3 is 63.53 μg/g,which meets the quality requirements of quartz sand used in photovoltaic glass panels.
