Sulphidizing Flotation of Copper Oxide Ore. The copper oxide ore in Dali, which contains % of copper and /t of silver, was beneficiated by sulphidizing xanthate flotation method. The flotation tests were carried out systematically with sodium sulfide as sulphidizing agent and butyl xanthate + ammonium dibutyl dithiophosphate as the combined collectors.

Pine oils, cresylic acid, and longchain alcohols are used for the flotation of copper ores. The flotation concentrates are then dewatered by clarification and filtration, resulting in 10 to 15 percent water, 25 percent sulfur, 25 percent iron, and varying quantities of arsenic, antimony, bismuth, cadmium,
Natural pH is recommended for gold flotation. Alternatively using soda ash for pH adjustment can reduce gold depression. Where gold is associated with pyrite in base metal ores where iron sulphides are depressed and report to the tailings, a separate tailings pyrite flotation .

Oxide copper ores in subdivided form may be concentrated in a flotation separation process by slurrying said ores in an aqueous solution of a flotation reagent followed by generating gas bubbles in the slurry to float the oxide copper and recovering the concentrated oxide copper from the surface of the slurry, wherein the flotation reagent is a quaternary hydrocarbyl ammonium or phosphonium ...
Ore sample flotation Cationic flotation Figure 5 shows smithsonite flotation from the ore sample as a function of the sodium sulfide dosage using Armac C. The results revealed that the smithsonite particle surface was not sufficiently sulfidized. The optimal dosage of sodium sulfide is up to about 7500 g/Mg.
To establish the flotation response and suitability of the collectors, series of benchscale flotation tests are conducted for the refractory oxide copper ores obtained from Yangla Mine in Yunnan province. A simple xanthate (PAX) is used as the sulphide collector and a chelating reagent of hydroxamate AM28 as the oxide collector. It is found and confirmed by mineralogical examination that AM28 ...
