Improving coarse particle flotation using the HydroFloat

Jun 01, 2018The typical drop off in recovery for coarse sulfide particles within industrial flotation plants is best illustrated by the size-by-size flotation data reported by Lynch et al. (1981) in the well-recognized "elephant curve" shown in Fig. 1.More recent size-by-size recovery data show little has changed in the past several decades to expand the applicable size range of froth flotation when

Recycle of Wastewater from Lead-Zinc Sulfide Ore Flo

Lead-zinc sulphide ore contains lead sulphide (galena), and zinc sulphide (sphalerite). In the first flotation stage, galena is rendered hydrophobic with an organic collector such as xanthate, while sphalerite is kept from floating by depressants, and in the second flotation stage, activator was used to activated zinc flotation. Since the organic regent used are different in the two flotation

Effect of Copper and Iron Ions on the Sulphidizing

The treatment of smelting slag has attracted much attention nowadays. This study investigates the influence of Na2S, CuSO4, and FeCl3 on sulphidizing flotation of copper oxide. The results show that a proper Cu2 concentration can increase the sulphidizing effect of copper oxide, while Fe3 inhibits the sulphidizing effect. Further analysis shows that Cu2#x2b; ions can reduce the surface

Hydrogen sulfide Wikipedia

Hydrogen sulfide is often produced from the microbial breakdown of organic matter in the absence of oxygen gas, such as in swamps and sewers; this process is commonly known as anaerobic digestion which is done by sulfate-reducing microorganisms. H 2 S also occurs in volcanic gases, natural gas, and in some sources of well water.
