· It is determined that Tecflote agents can replace or supplement thiol collectors used for flotation of copper-bearing sulfide ores. The concentration performance will be increased [ 21 , 22 ]. It was quite interesting to evaluate Tecflote agents as possible collectors for the flotation of copper-nickel sulfide ores. 1.

In this study, an attempt was made to recover copper from AbuSwayel deposit. A reverse flotation technique was applied leading to flotation of the accompanying oxide and sulfide minerals and gath ering copper oxide minerals in the sink product. The results showed that the application of such tech nique is possible under the optimum flotation conditions.

Copper ore usually contains about 0.5 to 2% copper that occurs in the form of disseminated and stringers. The run of mine ore is reduced from 150 mm to 25 mm size in Jaw and Cone crushers. The crushed ore is grinded in ball mills to −74 μm size. The ore is processed by froth flotation comprising rougher and scavenger cells.

Generally, direct froth flotation is not used to concentrate copper oxide ores, as a result of the largely ionic and hydrophilic structure of the copper oxide mineral surface. Copper oxide ores are typically treated via chelating-reagent flotation and fatty-acid flotation, which use organic reagents to ensure adsorption onto the mineral surface through the formation of

· In this study the flotation of a copper ore in the presence of talc and muscovite was studied. It was found that talc can affect copper flotation mainly via froth phase. The copper grade and recovery were affected in the presence of only 7% talc. On the other hand, muscovite influenced the pulp phase via affecting the pulp rheology.
