For all tests, rotor speed is maintained at 750 rpm, whereas air flow rate is set at 200 L.h −1.
Biotite is an important adsorption carrier in the constituent minerals of Beishan granite.

erals were mainly 20.36% quartz, 28% biotite, 31% potassium feldspar, and 3.1% limonite. The microscopic observations also showed that chalcopyrite, malachite, and chrysocolla were pre-sent in the limonite and biotite in the form of mechanical mixing. A New Technique for Recovering Copper From Complex Copper Oxide Ore by Flotation and
The optimal pH for the froth-flotation separation was determined for biotite, muscovite, and a mixed sample of biotite and quartz (i.e., to distinguish the two minerals by …

Correct water flow was calculated using the Stoke's Law, the target fineness of slimes fineness (p80 11 µm) and the diameter of the flotation cell. ... Overall flotation results show that MgO recovery behaves the same way with Li 2 O recovery in the spodumene flotation stage, which indicates that biotite and amphiboles have to some extent ...
A dissolution experiment using a mixture of biotite and muscovite, done at 150 °C for 7 days, indicated that hematite crystals formed mostly at the edges of biotite but not on …
To determine the optimal pH conditions of the froth-flotation separation process for treatment of F-enriched soil, the pure minerals (biotite and muscovite) known to cause F accumulation in the soil of the study site were purchased from Geoscience Resources (30-1291: biotite, 30-1251: muscovite), and were ground and sieved to obtain a particle ...
The flotation tests were performed in a conventional flotation machine 237 FL-A with 0.35-liter capacity cell and the impeller rotational speed 40 rev/sec. Batch flotation tests were carried out at room temperature. 100 g of ore sample was conditioned with tap water in a flotation cell and stirred for 3 min before adding any reagent; CaCl 2 and ...

3.3.3 Biotite. The typical load-depth curves of biotite are shown in Fig. 12. The load-depth curves of biotite presented a stepped shape and were not smooth, therefore the measured Young's modulus data of biotite is very discrete (Zhang et al. 2013).
