1994-5-1 The chemistry of galena flotation 725 Fine Particle-Galena Interaction The adhesion which can occur between particles of unlike charge leads to the phenomenon of "slime coatings" in mineral processing parlance or "heterocoagulation" in the language of the colloid chemist.

2001-1-1 The flotation of galena and sphalerite fines in the form of flocs, which is termed floc flotation, has been studied in the present work. The flocs formed through hydrophobic flocculation induced by potassium amyl xanthate (PAX) and kinetic energy input.

2014-12-10 flotation recoveries of galena and sphalerite are discussed in Chapter 5. The flotation results indicate that high dosages of xanthate collector of long chain length such as PNBX are detrimental to the flotation selectivity between galena and sphalerite. As expected, Cu(II) is a much stronger activator for sphalerite than Pb(II) ions. It is also
2004-10-13 The results of the bioleaching process of the galena flotation concentrates from ZGH Boleslaw S.A. by Acidithiobacillus ferrooxidans bacteria have been presented. It has been recorded that the final level of conversion of SS into SSO4 in bioleaching process is about 48% and it is two-fold higher than in the control examinations.
2016-6-11 The flotation time was 2 min at an air flow rate of 0.5 dm3min-1in each test. The flotation froth was scraped every 10 s to collect the floated particles. The dosage of collector in flotation was 5×10-4M KAX and the frother dosage was one drop of MIBC in all the tests, unless otherwise specified.
2019-5-15 The micro-flotation tests were carried out using a 250 cm3micro-flotation column cell which was mounted on a magnetic stirrer, and a magnetic stirrer bar was used for agitation. In this study, hand- picked pure galena particles were ground using ceramic balls, and sized to 106×53 µm. A 2 g sample was used for each flotation tests.
Yunnan lead processing project has complex lead ore to deal with. The main lead minerals are galena and lead alum. It applies the flotation sulphide ore desilting flotation oxidation ore processing technology according to the characteristic of lead ores. The final
2019-4-12 One of the important aspects of the flotation process is its kinet- ics. The quantification of kinetic parameters is becoming in- creasingly important for shedding light on the speed of in- dustrial flotation processes [22−23]. Flotation operations, as well as the associated kinetic and thermodynamic pheno- mena, are random processes.
