Collector type and pulp pH play an important role in the lead–zinc ore flotation process. In the current study, the effect of pulp pH and the collector type parameters on the galena and
is again based on two different types as cationic and anionic reverse flotation. In all these processes different types of flotation reagents are used. Another application is separation of malachite and azurite ore using sulfidization flotation. Keywords. Flotation, surfactants, collectors, activators, depressants, metallurgy. 1. INTRODUCTION
1. Introduction. In recent years, the processing of mining residues and more importantly flotation tailings have been an alternative way to secure sustainable development and metal supply [,,].Recycling of mining wastes results in multiple advantages including value metals recovered and environmental remediation .Froth
The flotation concentrate with the highest PGM recovery was leached using sulphuric acid in order to remove the base metals and further enrich it in PGMs. Extractions of 73.3% Cu, 82.9% Ni, and 8.
The collector activated by lead nitrate can selectively combine with scheelite and change its surface hydrophobicity so that it can be more easily removed from the pulp [25], [26]. As shown in Fig. 5 b, when 3.65×10 −4 mol/L BHA was the collector, the suitable pH range of BHA as scheelite flotation collector was 7–9. When pH≤6, the
Deionized distilled water was used for microflotation, microscopic imaging tests, and laser particle size analysis. 2.2. Methods 2.2.1. MicroFlotation Tests A XFG1600 type (mechanical agitation) flotation machine (Fruitful mine machinery factory, Luoyang, China) with the volume of 40 mL was used in the microflotation tests. The mineral
The actual ore flotation test uses an XFD flotation machine with a flotation cell volume of 1 L. The flotation machine speed is 1800 r/min, 400 g ore samples are taken each time, and the slurry
A combined process of flotation and highgradient magnetic separation was proposed to utilize Yulong complex copper oxide ore. The effects of particle size, activators, Na 2 S dosage, LA (a mixture of ammonium sulfate and ethylenediamine) dosage, activating time, collectors, COC (a combination collector of modified hydroxyl
Separation operations include gravity separation, flotation, magnetic separation, electric separation, picking, and chemical beneficiation.
05 Zinc oxide flocculation froth flotation method. Flocculation flotation is a flotation method for finegrained zinc oxide minerals. Before flotation, and then sulfhydryl carboxylic acid was used as a collector for zinc oxide. The advantage of this process are that no mud removal during flotation and the amount of sodium sulfide is reduced.

methyl cellulose xanthate (HCMCX) to enhance the flotation efficiency of fine copper oxide ore from Dongchuan Copper Mine, Yunnan, China. This collector achieved an excellent mean concentration containing 20.19% Cu with 88.39% Cu recovery, and the Cu recovery increased by 5.69% compared to that of amyl xanthate (AX).
The collector activated by lead nitrate can selectively combine with scheelite and change its surface hydrophobicity so that it can be more easily removed from the pulp [25], [26]. As shown in Fig. 5 b, when 3.65×10 −4 mol/L BHA was the collector, the suitable pH range of BHA as scheelite flotation collector was 7–9. When pH≤6, the
Amine flotation method, also known as cationic collector flotation method, is a commonly used flotation method for nonferrous metal oxide ores (copper, lead, zinc). It is used in malachite, azurite and chalcopyrite, etc. Amine collectors are selective for oxide copper, because amines also have a capturing effect on many gangues.
The Kansanshi Mine (First Quantum Minerals Ltd) treats a mixed sulphide/oxide coppergold vein deposit. Until June 2009, the sulphide and oxide minerals were respectively recovered by the well established xanthate flotation of sulphides and acid leaching of soluble oxide copper. The mixed (transitional) sulphide/oxide ores were
