These temperatures are not sufficient to bring about biotite-induced dehydration melting and, since muscovite-induced melting is completed during the compressive phase, no significant increase in melt fraction is to be expected in the upper portion of the migmatitic layer, at the post-thickening thermal peak.

and a concentrate with a high sulfur content (0.059% Cu and 15.03 g/t Au contents, and 83.15% Cu and 21.28% Au recoveries). The capacity of the subsequent leaching process was reduced by 25%. Ammonia pretreatment was introduced to decrease the adverse effect of copper on cyanidation leaching for the copper concentrate.

The concentrate was filtered, dried and weighed to calculate the flotation recovery. The mass of mineral used in each test was 50 g for muscovite and 100 g for quartz. The initial volume of water added for each test was 1.3 L. The conditions examined for muscovite included pH (pH 4, 7.5 and 10) as well as collector dosage (100, 250 and …

You can thicken watery tomato pasta sauce by either adding more tomatoes/tomato paste or by reducing it further over low heat (to evaporate some of the water). If you don't mind altering the taste and texture, you could add a thickening agent (like tapioca/corn starch) instead. Of course, it always helps to understand why your …

Because the sharpness of separation deviates from the ideal case, a recovery loss must be incurred to produce a final concentrate that meets grade specifications. Figure 5 shows that a cut point of 2.90 produced a concentrate grading 6.29% Li 2 O; beyond this cut point, the grade increased and lithium recovery …

Muscovite is a common mineral that belongs to the mica group. It is a silicate mineral that is characterized by its thin, sheet-like structure. Muscovite is composed of potassium (K), aluminum (Al), silicon (Si), and oxygen (O) atoms arranged in sheets, and it is known for its excellent cleavage, which allows it to be easily split into thin, flexible sheets.

The results indicated that increasing the regrinding concentration via thickening can improve the grinding efficiency and, thus, shorten the separation process. With thickening, a high-grade intermediate concentrate of 96.01% was obtained after three steps of cleaner flotation, which is close to the final concentrate after five steps.

In this circuit, "conventional thickening" with no flocculant addition is performed to dewater to the slurries. Froth flotation is used to produce a concentrate (FC) of hydrophobic gold-bearing minerals at ~30 wt.% solid. The concentrate is then thickened to ~50 wt.% solid loading for storage, prior to bio-oxidation.

The specific gravity of spodumene is between 3.1 and 3.2; this makes it slightly heavier than most gangue minerals such as quartz (2.65), albite (2.60) and muscovite (2.8). The spodumene, therefore, sinks while gangue minerals float in dense medium of appropriate specific gravity, and thus separated from each other.
