Selective Flotation of Elemental Sulfur from Pressure Acid ...

An efficient flotation process was developed to selectively recover elemental sulfur from a high-sulfur pressure acid leaching residue of zinc sulfide concentrate. The process mineralogy analysis showed that the sulfur content reached 46.21%, and 81.97% of the sulfur existed as elemental sulfur which was the major mineral in the residue and primarily existed as pellet aggregate and biconical ...

Performance Recognition for Sulphur Flotation Process ...

As an important indicator of flotation performance, froth texture is believed to be related to operational condition in sulphur flotation process. A novel fault detection method based on froth texture unit distribution (TUD) is proposed to recognize the fault condition of sulphur flotation in real time. The froth texture unit number is calculated based on texture spectrum, and the probability ...

Sulphide Flotation - an overview ScienceDirect Topics

Sulphide Flotation. In practice, sulfide flotation plants operate at pulp potentials that are in the range of +50 to +200mV versus SHE (Grano, 2004) and the value depends on the pulp pH, type and quantity of sulfide minerals, the type and quantity of grinding media (Rao et al., 1976), and the amount of air–pulp contact in and after the grinding circuit (Teague et al., 1999b).

2011-9-1  The recovery of elemental sulfur is highly dependent on the particle size distribution of the sulfidic micropellets. Typically, these pellets should be greater than 44 μm and less than 150–200 μm in diameter.If the particles become too fine, they behave like slimes in a flotation circuit and report to the tailings, thereby reducing elemental sulfur recovery.
