Gold Flotation Mineral Processing & Metallurgy

13/07/2016 The latter is a higher xanthate which is a strong and non-selective promoter of all sulphides. Amyl and butyl xanthates are also widely used. Ethyl xanthate is not so commonly used as the higher xanthates for this type of flotation. The liquid flotation

Flotation of Gold and Gold-Bearing Ores ScienceDirect

01/01/2016 Sulfide ions appear to act as flotation activators at low concentrations (<10 −5 mol/L) and as a strong depressant at concentrations >10 −5 mol/L (Aksoy and Yarar, 1989). The addition of sulfide ions converts some coatings on mineral surfaces in sulfides (Healy, 1984) and subsequent xanthate addition will promote flotation. For successful activation, the sulfide activator should be added

Advancing flotation process technologies to maximise gold

13/09/2017 A flotation process is one method used throughout the industry to recover gold. It’s a very cost-effective method for concentrating gold, and is a desirable process used for the upgrading of low-sulphide and refractory ore for further gold recovery treatment. Froth flotation is a process used to selectively separate hydrophobic materials from

Minerals Free Full-Text Flotation of Carbonaceous

The use of alkaline pressure oxidation to pretreat refractory gold ore often results in insufficient gold recovery (<60%) in downstream thiosulfate leaching. To improve gold recovery, flotation was considered for the separation of carbonaceous matter (C-matter). In this study, the effect of MIBC on C-matter flotation was investigated to understand the role of the frother in bubble and froth

strong dispersive attraction for water (Dunne, 2005). The floatability of gold is known to be enhanced by surface coatings of some organic compounds and silver content (either as rimming or in the form of electrum), while calcium ions and some forms of sulphur can act as depressants. It has been suggested that when native gold surfaces are hydrophobic due to contamination by organics in nature
