Agar (1985) considered two phenomena which are opposite in their action in affecting the flotation kinetics. Some solids in the slurry are naturally hydrophobic and will have air bubbles attached to them during the conditioning period. Hence, their flotation starts even before starting the air flow. On the other hand, when air flow is started, several seconds elapse before a full depth of ...

The optimum values the main variables affecting this process were determined. These variables are of pH of copper solution, initial concentration of copper ions in sample, air flow rate and flotation time. An atomic adsorption spectrometry PERKIN ELMER model 2280 was used to determine the copper content of the wastewater. The copper removal efficiency was calculated with the equation: R% = [(C ...
· Users in the investment of copper flotation production line, generally also has planned the size of their production line plant, after the civil plant also needs a lot of money, so it is a major factor that will affect the user's investment in this production line.

· 3 Summary of the copper mineral flotation process (1) Copper minerals (such as chalcopyrite and covellite) that do not contain iron are similar in floatability. Cyanide and lime have weaker inhibition on them, so a large amount of lime can be added to inhibit pyrite in the separation of copper and sulfur without seriously affecting the ...
The aim of this study is to apply process mineralogy as a practical tool for further understanding and predicting the flotation kinetics of the copper sulfide minerals. The minerals' composition and association, grain distribution, and liberation within the ore samples were analyzed in the feed, concentrate, and the tailings of the flotation processes with two pulp densities of 25wt% and 30wt%.
Copper "activation", involving the surface adsorption of copper species from solution onto mineral surfaces to activate the surface for hydrophobic collector attachment, is an important step in the flotation and separation of minerals in an ore. Due to the complexity of metal sulfide mineral containing systems this activation process and the emergence of activation products on the mineral ...
· The treatment of smelting slag has attracted much attention nowadays. This study investigates the influence of Na 2 S, CuSO 4, and FeCl 3 on sulphidizing flotation of copper oxide.

· Generally, after the activator (copper sulfate) is added to the pulp, the mixed emulsifier of xanthate, pine oil and water can be added at one time, which is better than the multiple addition of the flotation reagent, and the dosage of the flotation reagent will be saved. Pyrite can use xanthate as the collector in acidic, neutral and weak alkali slurries. The acidtreated pyrite has good ...
· Economic of Copper Processing. The balance between milling cost and metal losses is crucial, particularly with lowgrade ores. Most mills keep detailed accounts of operating and maintenance costs, broken down into various subdivision, such as labor, .
copper sulphate prior to collector addition could cause the chromite to be hydrophobic and hence amenable to true flotation (Wesseldijk et al. 1999). The presence of chromite in the concentrate can result in inefficient smelter operations since it is a member of the spinel group that forms compounds that are stable to temperatures of up to 2000°C (McKenzie, 1996). As a result, there is a ...
