In order to avoid the influence of impurity ions on the flotation test, the flotation materials were prepared by grinding with ceramic ball media. After adding different types and amounts of grinding aids, flotation materials with the quartz content of 90% -0.074 mm and 65% -0.043 mm were obtained by controlling the grinding time.

Iron ore is the main raw material of the iron and steel metallurgy industry, but quartz in iron ore reduces metallurgical efficiency and increases metallurgical costs. Therefore, iron ore desiliconization by flotation plays an important role in the iron and steel metallurgy industry. In this study, 4-tert-butyl-catechol (TBC) was designed as a collector to directly float out hematite …

between the flotation process and the flotation effect still need to be completed. In our previous work, we examined the influence of OCT, SDS, and CTAB surfactants on the flotation of quartz by DDA. It is found that all three surfactants can co-adsorb with DDA on the surface of the quartz, thus strengthening the hydrophobicity of the quartz

In order to enhance the reverse flotation effect of hematite, dodecyl trimethyl ammonium chloride (DTAC) and a mixed anionic/cationic collector of DTAC and tall oil were selected for flotation studies on quartz and hematite.
