202211 · As an environmentally-friendly reagent, FeCl 3 might exhibit a potential inhibition against pyrite during its flotation separation from sphalerite [41]. In this study, using 4-amino-5-pentyl-1,2,4-triazole-3-thione (APTT) as a collector, the floatability of sphalerite and pyrite was explored through micro-flotation tests.

2024525 · In general, the direct separation between naturally hydrophilic cathode active materials (lithium oxides) and inherently hydrophobic anode active materials (graphite) can be achieved through flotation. During flotation, particles are separated based on the differences in their surface hydrophobicity.

201921 · The separation of covellite and pyrite is difficult because of their similar floatability. Furthermore, the efficient separation of covellite from pyrite is advantageous for the recovery of copper and enhances its economic value. Therefore, an effective method for the separation of covellite from pyrite by flotation is required.

202271 · Abstract Galena, sphalerite, and pyrite are important metallic sulfide minerals and are often associated with one another. In the flotation separation of galena-pyrite mixed concentrate, large amounts of lime (CaO) are used for the depression of pyrite. In this study, the negative effects of lime were reduced by using an efficient depressant …
