Significantly affected copper recovery whilst ph was found to also significantly affect cobalt recovery.Keywords flotation, process optimization, taguchi orthogonal array, anova.Introduction froth flotation is widely used for separating base metal sulphide minerals in complex ores.
Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 99.99 pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different.
Copper sulphides are selectively floated from pyrite ores at high phs in excess of 11.It is less clear how the free gold behaves under these conditions.In addition, for extra gold recovery, further collectors are added, such as the monothiophosphates, which are known to be selective gold collectors.

Today such ores which would be regarded as relatively rich in copper are scarce the great majority of mines contain the metal in finely disseminated particles which aggregate anything from 2 percent down to 1 percent or even 0.8 percent of copper.Thus to obtain metallic copper, up to 99 percent of the material mined must be removed as waste.
Asian journal of chemistry vol.10 2010, 7874-7882 effect of microwave radiation on the floatation of copper sulfide ores erol kaya department of mining engineering, dokuz eylul.
The flotation method is edno-molybdenum ore, including grinding ore and collective flotation of copper and molybdenum in alkaline environment, created lime, characterized in that the collective flotation is carried out in the presence of the collector aero-mx 3601 and the expander, then the bulk flotation concentrate after evaporation and desorption heated slurry to 40-60with live steam in.
Copper flotation mineral processing metallurgy.The flotation of native copper ores is nearly always preceded by gravity concentration in jigs and tables not only because the combined process is more economical as regards costs, but also because the copper often occurs as large grains which flatten out during grinding and cannot be broken to a size small enough for flotation.
Copper-cobalt ores.Various cobalt bearing minerals have economic significance including cobaltite coass.Carrollite cuco.Ni2s4, and linnaeite co3s4.These are often associated with copper minerals and pyrite and pyrrhotite iron sulphides.Two different flotation separation strategies are used.
The copperleadzinc ores have an origin similar to copperzinc and leadzinc ores, the exception being those ores that contain copper, lead and zinc as the principal economic minerals.In addition, some of these ores contain significant amounts of precious metals and, more rarely, cobalt and nickel.
