What is the role of depressant in froth floatation process?

For example, sodium cyanide is a depressant used for an ore containing Z n S and P b S. N a C N forms a layer of the complex N a 2 [Z n (C N) 4 ] on the surface of Z n S and prevents it from forming a froth. Thus, it acts as a depressant. However, N a C N does not prevent P b S from forming froth and allows it to come with froth.

Continuous Flotation Testing To Recover Cobalt From Missouri

The major cobalt source in the ore is the mineral siegenite. Separation and concentration of siegenite by froth flotation is complicated by the mineralogy of the ore. The siegenite is often present as an intimate replacement in­ tergrowth with chalcopyrite (fig. 1), sphalerite, galena (fig. 2), and the iron sulfides, pyrite and marcasite.

PDF Influence of water resources and metal ions on galena

selectivities, froth stability and flotation kinetics. The various water resources employed during galena flotation caused activation, depression or selectivity effects on minerals due to the presence of different ions in solution. Metal ions in these water resources were adsorbed by the ore, whilst ions associated

7 Factors Affecting Froth Flotation Process - JXSC Machine

At present, the upper limit of flotation particle size is generally 0.25-0.3 mm for sulfide minerals; 0.5-1 mm for natural sulfur; and the upper limit of particle size for coal is 1-2 mm.3.Avoid muddy as much as possible. When the flotation particle size is less than 0.01 mm, the flotation index will decay significantly.

Froth Flotation Method - JXSC Machine

Cyanidation of froth flotation + flotation concentrate A small amount of concentrate is obtained from gold-silver quartz vein sulfide ore by flotation, and then cyanide treatment is carried out. Compared with the whole slime cyanidation process, the froth flotation method concentrate process has the advantages of no fine grinding of all ores, saving power consumption, small plant area and less capital investment.

The Application of Xanthate in Froth Flotation Process

4. Xanthate Application in Galena Froth Flotation. The surface of galena is hydrophobic, so it’s easy for flotation. Xanthate is the common collector for the flotation of galena. When the pH is high, the galena is easily floated by the ethyl xanthate. The optimum pH for flotation is 7-8, which can usually be adjusted with sodium carbonate.
