In copper flotation, gold is floated with copper minerals, while pyrite is depressed in order to produce a saleable copper-gold concentrate. Then, the depressed pyrite is activated and floated to recover the remaining gold associated with pyrite (Zheng and Manton, 2010).

This flotation step is conducted at alkaline pH. In the case where galena is floated and the copper minerals are depressed, copper depression can be achieved by using sodium sulphide, hydrosulfite, lime, cyanide, zinc-cyanide and/or ferricyanide complexes. Selection of flotation reagents and frothers is an important, even critical, consideration.

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. ... froth flotation, 2) thickening, 3) smelting, and 4) electrolysis.

a flotation device referred to as mini pilot plant (mpp), which is able to run continuous flotation tests with drill core samples. since then this equipment has been used to define the flotation circuit and process conditions during the pre-feasibility phase of CVrd's copper sulfide projects. Until now, the mpp results had not been validated

Flotation of a copper sulphide ore from Okiep using thiol collectors and their mixtures The Journal of The South African Institute of Mining and Metallurgy VOLUME 105 NON-REFEREED PAPER MARCH 2005 201 Figure 1—The final cumulative copper recovery vs. collector dosage obtained with C2-X, di-C2-DTP and di-C2-DTC in the flotation of the Okiep copper ore

copper. Batch flotation tests were used to assess the performance in terms of mass-water recovery, sulphur grade-recovery and copper grade-recovery relationships and the Klimpel rate constant for copper recovery. The results showed that the di-ethyl-dithiocar-bamate (di C2-DTC) was the weakest collector of copper sulphide minerals.

In addition to the two primary flotation agents there are also a number of modifying and conditioning reagents, which control a variety of ore and flotation circuit variables [13]. For instance, lime is a depressant for pyrite (FeS2) in the flotation separation of copper sulfides.

2. 2. Flotation Procedure All the flotation test-work was done using the Denver laboratory machine with a 1.5l 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

The above flowsheet is designed for the treatment by flotation of copper as chalcopyrite with gold and silver values. The ore, ranging from 60-65% silica, with pyrite, arsenopyrite, and calcite with 3 to 4% copper.

13.1 SOME GEOLOGICAL AND MINERALOGICAL FEATURES OF COPPER-ZINC ORES RELEVANT TO FLOTATION. The geology and mineralogy of copper-zinc ores is similar to that of copper-lead-zinc ores, and in most cases, these ores are grouped together with copper-lead-zinc ores.

Gold, silver, copper, lead, zinc, molybdenum, iron, potash, phosphate, and even sand for glass are often processed by froth flotation. Without froth flotation, many of the metals and minerals used every day in our modern world would be much more expensive.

A Copper Flotation Flowsheet. Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial.

Designed to operate across a broad range of alkalinity levels and provide faster flotation kinetics, our flotation collectors have become the industry standard in the recovery of copper, gold, molybdenum and other metals.
