Particle Sizing In Sulfide Ore Flotation Slurry

Effect of particle size on flotation performance of complex

Nowadays, particle size is often measured and controlled in flotation concentrators. In this study the dependence of the froth structures on the particle size variation was investigated on the batch flotation of a sulfide ore from the Merensky reef In short, as a special industrial suspension, the rheological behavior of the flotation slurry in the separation process is determined by variables such as the solid concentration, particle size distribution, A Brief Review of Micro-Particle Slurry Rheological

Zinc Recovery from Wulagen Sulfide Flotation Plant Tail by

Separating oxidized zinc minerals from flotation tailings is always a challenge. In this study, a flotation tailing from Wulagen zinc mine in China (Zn grade < 1%) was processed using froth flotation with combinations of amines (OPA 10, OPA 1214, OPA 13, DDA) and Na2S to study the effects of these amines on the zinc recovery as well as The rheology and flotation of nickel-copper sulfide ore and serpe ntine was investigated on a laboratory scale.

Effect of platy gangue minerals in sulfide flotation: Part I

1. Introduction. In the beneficiation of sulfide minerals from their ores by froth flotation, the non-sulfide gangue (NSG) minerals are predominantly silicates (Edwards et al., 1980, Firth and Nicol, 1981, Arnold and Aplan, 1986, Bremmell et al., 2005, Tabatabaei et al., 2014, Burdukova et al., 2008).A sub-class of the silicates is the In addition, the effect of particle size on flotation performance has been well established [25,26], and the relevant studies commonly involve iron ore flotation. The significance of particle size and, to a limited extent, that of the solid concentration on flotation performance was first reported by Trahar in 1981 [ 15 ], who examined both Effect of Solid Concentration and Particle Size on the Flotation

Combined microflotation effects in polymetallic ores beneficiation

During flotation, the following reagents were used: sodium sulfide (Na 2 S) for sulfidization of minerals, zinc sulfate (ZnSO 4 *7H 2 O) and sodium cyanide (NaCN) for depression of zinc minerals and pyrite. Sodium butyl xanthate (C 4 H 9 OS 2 Na) is used as a collector; oxal T-92 (CH 3 CHOHCH 3) is used as a frother.Before each flotation run, Sulfide minerals are usually enriched and separated from each other by flotation, and the optimal feeding particle size range −0.15 + 0.038 mm was chosen as the requirement grade for sulfide ore in cassiterite-polymetallic sulfide ore, with grinding particle size a of sulfide ore Should the slurry density in a grindingGrinding Optimization of Cassiterite-Polymetallic Sulfide Ore

Full article: The Direct Leaching of Nickel Sulfide Flotation

The iron-to-magnesium ratio in the nickel concentrates destined for smelting is a key parameter that influences smelting temperature and slag viscosity (Mayhew et al. Citation 2013; Senior and Thomas Citation 2005), hence emphasis is placed on the rejection of Mg-bearing gangue during flotation of nickel sulfide ores (Lotter et Flotation tests were conducted on ground ore mixed with different amounts of sized mica (platy) or silica (globular) minerals. This essentially allowed us to alter the already present non-sulfide gangue (NSG) composition in a controlled manner and to investigate gangue size and shape effects on flotation recovery.Effect of platy gangue minerals in sulfide flotation: Part I
