Copper Flotation

Although basic porphyry copper flotation and metallurgy has remained virtually the same for many years, the processing equipment as well as design of the mills has continually been improved to increase production while reducing operating and maintenance costs Also, considerable attention is paid to automatic sensing devices and automatic controls in order to assure maximum metallurgy and ....

Copper Flotation

Sep 12, 2012· This shows you the froth produced by flotation on a porphyry copper ore of about 15% Cu You see the rougher flotation, the cleaner and scavenger circuit It is a very small pilot plant small ....

Froth Flotation of Copper

Sep 12, 2012· Copper is recovered by Froth Flotation in the mini float plant Standard rougher and cleaner circuit Nice clean metallurgy from the 1% copper rock...

Rougher Scavenger Flotation Cells

Introduction To Mineral Processing Additional copper collector is often added to the scavenger flotation cells and may be added at several other points the froth enriched in copper and molybdenum is removed from the flotation roughers and scavengers this enriched material is now called the rougher concentrate or cleaner feed the combined rougherscavenger concentrate may be...

Rougher flotation of copper minerals in columns

Both samples were coarser than standard granulometric size used in conventional rougher flotation A series of eight tests, in duplicate, were carried out with sample a The conditions and metallurgical results are shown in Table 1 If tests 1 and 2 are compared, it can be seen that air flow improves Cu recovery...

Flotation of Copper Sulfide Ores

The floatability of molybdenum during copper flotation also depends on many factors, including type of collector, type of frother, flotation pH and type of hydrocarbon oil used During the flotation of copper molybdenum ores, fuel oil or kerosene is added to the grinding to enhance molybdenum recovery...

copper ore flotation test

Marketable copper concentrate at 9195% recovery was produced utilizing a highpH bulk sulphide rougher flotation and 2 cleaning stag Because of increased levels of Zn of the ore body, a Cu/Zn separation circuit was initiated in early 2010 following an intensive laboratory test work program...

Simulation of Flotation Plants

For a greenfield plant design, the flotation models are typically based on kinetic laboratory tests carried out both for the rougher and cleaner stag It is also common to carry out closed loop locked cycle laboratory tests and pilot plant test runs to model-fit and calibrate the plant design simulation model...

Flotation of Nickel

2 2 Flotation Procedure All the flotation test-work was done using the Denver laboratory machine with a 15l stainless steel flotation cell The required mass of nickel-copper sulphide ore material ground to 70% passing 75 µm was weighed and placed in the flotation cell This was followed by the addition of distilled water to about...

Benchmarking Performance of the Two

copper concentrator rougher flotation feed showed retention time gains on the order of 6 to 9 times when compared with conventional flotation equipment This finding has the potential of reducing capital demands for rougher flotation circuit designs when incorporating the StackCell The results from test ,...
