created in the flotation process is of great importance to the efficiency of the mineral separation achieved. Meanwhile, it is believed that frother transport between phases is perhaps the most important reason for the interactive nature of the phenomena occurring in the bulk and froth phases in flotation, as frother adsorbed in the surface of rising bubbles is removed from the bulk phase......
that the distribution pattern of (32%, 32%, 20%, 16%) can produce the best recovery (87.75%) in comparison to other examined distribution patterns. Key words: copper sulphide ores; flotation reagents...) are typically used in the flotation of porphyry copper and copper molybdenum ores[6]. In copper flotation plants, an increase of 1%-2% in recovery and/or grade is economically remarkable. In this work, reagent......
DESIGNS AND APPLICATIONS OF COLLECTORLESS FLOTATION FLOWSHEETS OF SULPHIDE ORES+Sun Shuiyu1; Li Bodan1; Wang Dianzuo2(1.Department of Mineral Engineering, Central South University of Technology.... It is found that there exists a great difference between the flotation behavior of every two minerals. On the basis of this phenomenon, new flotation flowsheets for the separation of sulfide ores have been......
the traditional flotation conditions, such as at pH 9-9.5, no natural pyrrhotite floatability is observed, pyrrhotite floatability with collector is low, and activators (copper and lead) lose...) and sodiumdithionite (Na2S2O4). All reagents in the flotation tests were of analytical reagent grade except that the frother butyl aether alcohol was in the industry reagent grade. The dosage......

of the two were floated in a lab-scale flotation cell with collector dosage, frother type and dosage, and pH varied to determine the optimum experimental conditions. The diatomite sample and products... Tests were conducted to investigate the influence of different frother type and dosage on the flotation of diatomite and AC with the results shown in Figure 3. In this figure, the AC floating ratio......
particles to air bubbles due to their small mass [6-11]. Accordingly, it is a great challenge for conventional froth flotation to recover molybdenite fines from the finely-disseminated molybdenum ores... of molybdenite in the conventional flotation. Pine oil was used as the frother. Pine oil, kerosene and transformer oil were industrial chemicals. Additionally, calcium oxide, sodium silicate, sodium sulfide......
and frother. The conditioning times for collector and frother were 2 min and 1 min, respectively. The flotation time was 4 min. 2.3 Infrared spectrum examination 1.0 g sample was immersed...

%, respectively, the grade of Zn of marmatite concentrate is 42.5%, and the recovery of Zn is 91.25%. Key words: flotation; pulp potential; N,N’ diphenylamino-dithiolphosphoric acid; lead-silver-zinc ores...-iron sulfide ores. Under appropriate pulp potential in PCF process, the flotation speed is fast and the flotation flowsheet is simpler than commonly used ones. The key factor of PCF is the redox......
