The biotite and quartz powders were conditioned with flotation reagents according to the flotation process while being adequately stirred for 30 min to acquire suspensions. Afterward, the suspensions were filtered, rinsed three times, and the solids were dried in a vacuum oven at 30 °C to obtain the prepared samples.

Selective flotation of muscovite from a material containing muscovite (15.4%), biotite (13%), and siliceous gangue (quartz and feldspar), using a mixed collector system of sodium oleate and dodecylamine acetate has been described. Muscovite is found to float in preference to biotite, when the pulp is initially conditioned with oleate followed by amine …

anhydrite. Igneous biotite is rimmed by shreddy bio-tite or alkali feldspar, and generally contains small exsolved grains of rutile. Both the igneous and the shreddy biotite in these rocks are lower in Ti and higher in Mg than biotite from unaltered samples. Pyrite and chalcopyrite occur as minute grains in both biotitized hornblende and ...

To recover potassium from feldspar, a biowaste, i.e., eggshell, was used. The chief composition of eggshells is calcite. As it is a rich source of Ca, hence it is used with HCl to produce calcium chloride. Feldspar is an aluminosilicate mineral that bears potassium in the interstitial sites. To unlock the potassium from the interstitial sites, it was roasted with …
