2021. 6. 25.The ground mica also reduces checking and chalking, prevents shrinkage and shearing of the paint film, provides increased resistance to water penetration and weathering, and brightens the tone of colored pigments. Ground mica also is used in the well-drilling industry as
1988. 3. 2.Ahydrated, sodium phlogopite mica with a c -axis spacingd 001of 12.23 & 197; made by careful low-temperature leaching, showed extremely high selectivity for cesium. This newly discovered cesium ion sieve is useful in the decontamination as well as immobilization of cesium at room temperature through chemical bonding and may find appli ions in nuclear waste disposal and in Cited by: 15
2020. 7. 24.Since mica and gangue have different difficulty in passing through the sieve, the purpose of separation can be achieved. When separation, the sieve with more than two layers with different sieve surface structures will be used. Generally, the first layer of screen is strip-shaped, and the second layer of screen is square.

2019. 8. 13.The mica wind selection process is generally: crushingscreening and classifi ionwind selection. After the ore is crushed, the mica is basically formed into a flaky shape, and the gangue mineral feldspar, quartz and the like are in the form of
In this study, the possibility of reducing natural mica particles to nanosizes without damaging its surface properties and smooth flake shape for pearlescent pigment appli ion was investigated by using the soni ion delamination method. For this purpose, the layer charge density of the natural mica mineral was reduced using surfactant intercalation followed by maximum exfoliation of mica
2019. 11. 1.Effect of leaching time. The effect of leaching time was investigated in the range of 1–6.5 h. The results are plotted in Fig. 6, which shows that the leaching time had a remarkable effect on the lithium extraction. As the reaction time increased from 1 to 3 h, lithium extraction efficiency increased from 44% to 84%.
2011. 11. 1.The standard leaching procedure was undertaken for 30 min to ensure maximum extraction. After leaching the samples were filtered, the leach solution filtrate collected and the residues dried. The lithium, rubidium and iron analysis of both products were determined by AAS. 3. Results3.1.
