The paper presented outlines the scientific approach taken to improve the metallurgical efficiency of a modern plant at Athens Mine. The plant is based on the CIP method of gold recovery with copper concentrate as a major by-product. In the early stages of the operation the overall gold recovery achieved averaged 61% and copper recovery was 74%.

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
I have been given a project on optimization of copper concentrate grade so as to improve copper and gold recovery. I need help on the main factors which I have to consider in my project. The targeted copper concentrate grade at the plant is 18- 20%Cu, but currently the target is not achieved. The p

The details of the experimental techniques used are as follows: Improving flotation recovery of copper sulphides 1199 Sample preparation The lump ore samples were air dried by spreading the rocks in stainless steel trays in ambient atmosphere for 24 hours.
Nov 12, 2013· Magnetic conditioning of flotation feed has been shown to improve the flotation of <38 μm paramagnetic minerals consistent with selectively aggregating these paramagnetic minerals. The process was evaluated using shift composite samples that were analysed for copper and gold.
Improving copper flotation recovery from a refractory . Lime is commonly used as a pH regulator and depressant against iron minerals during the flotation recovery of copper minerals from copper porphyry sulfide ore. It can also depress copper oxide, secondary copper sulfide or gold minerals ( Allan and Woodcock, 2001, Sun, 2001, Liu et al ...

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
This study focused on the development of a new method, regrind-flotation pre-treatment, to improve the performance of the CIL (Carbon-in-Leach) circuit at copper-gold concentrators. Occlusion of gold by iron sulphide gangue minerals and the fine grain size of gold associated with them contribute
The flotation behaviour of low grade, coarse composite particles for two porphyry copper ores was studied. Different grinding times were employed to obtain size distributions for the flotation feed (d 80) ranging from 150 to 320 μm.Copper containing particles in the fine to intermediate size ranges were recovered in the rougher flotation stage.
depression strategies improve recovery and grade of copper, gold recovery is very often affected due to its fine-inclusions (~1-3 µm) in pyrite and non-sulphide gangue minerals . Also, selectivity between chalcopyrite and pyrite in Cu-Au ores is a challenge due to unintentional activation of pyrite as a
