The process involves two basic flotation methods: (a) fatty acid flotation of oxide copper minerals from siliceous ore, and (b) sulphidization of oxide copper minerals followed by Ion flotation is an efficient separation technique for the recovery of metal ions from dilute aqueous solutions. Provided that both the collected metal and the surfactant are recovered from the foam phase, it could be considered as an alternative to ion exchange, adsorption or solvent extraction in hydrometallurgy.

The copper content achieved to 50% ~ 55% through flotation by adding 500g/t of lime (pH 9 ~ 9.5), 10g/t of cresol (ing agent), 60g/t of ethylxanthate, 35g/t of amyl xanthate, 1kg/t ofIntimate knowledge of the mineralogical assembly of the Yushui complex ore rich in Cu, Pb, and Ag is essential if efficient separation processing is to be conducted.

PGM extraction from oxidized ores using flotation and leaching

Direct leaching of oxidic PGM ore using different acids yielded relatively low PGM extractions. Leaching in hydrochloric acid achieved extractions of 36.6% Pt and 8.8% Pd, nitric acid achieved extractions of 34.5% Pt and 7.1% Pd. The best leaching results were obtained using aqua regia, with extractions of 48% Pt and 24.5% Pd.The flowsheet contemplates a six to seven day leach-wash cycle with one tank being discharged and charged each day. In leaching plants of capacity illustrated by this flowsheet recovery of copper normally effected range from 80 to 90% of oxide copper and 70% or more of sulfide copper from average ores.

Mineral Processing Flowsheet Development SpringerLink

Abstract. Metallurgical testing is the most essential part of any mineral processing flowsheet development. Its objectives must therefore be clearly defined. These are discussed together with the importance of the choice of the samples required for the test program. Rather than describing testing procedures, stress is laid on how the testoxide flotation. Over-grinding of the brittle minerals is avoided by stage grinding and careful selection of equipment. We have experience in diverse regimes for treatment of a wide range of oxide minerals such as • barite • cassiterite • copper, lead, and Flotation SGS

The traditional method applied for the flotation of copper oxide or mixed ores is sulphidisation, which was first developed with industrial success on Pb–Zn oxide ores in Australia (Crozier, 1991). The average recovery difference between the laboratory experiments performed on the flotation feed and the plant results was around 9%.156 International Journal of Sciences: Basic and Applied Research (IJSBAR) (2017) Volume 34, No 2, pp 145-165 From plant practice, the treatment of oxide copper and copper cobalt ores is being carried out by the following methods: a) Sulphidisation flotation method, b) The carboxylic/ fatty acid process and c) The use of alkyl hydroxamates/ chelating reagents.A Review of the Flotation of Copper Minerals Academia.edu
