) as the depressant were studied by flotation test, adsorption measurement and infrared spectroscopic analysis. Single mineral flotation test shows that the slurry oxidation environment and the proper oxidation...] indicate that sodium humate can be used as pyrite depressant in the separation of chalcopyrite and pyrite at lower pH values. The studies on the flotation behavior of pyrite and arsenopyrite......
is the better depressant for fine magnesite. The effect of corn starch on the flotation of quartz is complex. Key words: magnesite; quartz; particle size; regulator; reverse flotation ......

the alkyl benzene sulfonate collector. Starch is found to be an effective depressant for gangue minerals in alkyl benzene sulfonate flotation. Moreover, slimes are found to have an adverse effect... to enhance separation. Sodium silicate was first tested as a depressant for gangue minerals but proved to be ineffective. Then the starch was tested. The results can be seen in Table 4. The test......
