Flotation data for the design of process plants Part 2 – case studies R. C. Dunne*1, G. S. Lane2, G. D. Richmond3 and J. Dioses2 The Cadia Hill Gold Mine and the Hellyer copper, zinc and lead plant present different problems with widely different target grind sizes, liberation characteristics. The contrast is between Hellyer s
Flotation is the most widely used method in copper mine production. The copper ore pulp is stirred and aerated, and the ore particles adhere to the foams under the action of various flotation agents. The foams rise to form a mineralized foam layer, which is scraped or overflowed by the scraper.
Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered …
The bulk flotation and the sulfide flotation of copper from atmospheric leaching cake in the future copper ore processing plant at the Udokan deposit is planned to be carried out at pH 9.0–10.5 and 5–6, respectively. Lime milk will be used to form and maintain the pH medium. One problem in the flotation process is the presence of sludges.
In this paper, recorded copper minerals flotation products results are shown, including lead underflow (copper flotation input), copper concentrate and copper …

The plant cells averaged 10% < 1 mm bubbles while the pilot plant cells averaged 50%. This benchmarking study identified possible operating challenges, which can assist the Toromocho expansion plant in making a range of changes to improve the copper recovery in the flotation circuit.
The process of copper concentration consists rough flotation and three stages of cleaners. On the rough flotation copper minerals and pyrite are collected, then in three stages of cleaners...
flotation models are linked. For example, a laboratory test conducted on a drill core sample, intended to represent a portion of the orebody, is conducted at a specific grind (represented by a P 80). However, when that ore is actually processed through the plant it may well be (and in many cases most likely will be) at another P 80 ...

Factors Directly Affecting Molybdenite Flotation: The average molybdenite recovery in the copper concentrator for the first nine months of 1980 was 67.13%. In recent months, there has been approximately an 80% recovery of the molybdenite in the sand and slime rougher floats.
Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain …

In current flotation operation, copper grade in flotation tailings is generally higher than 0.30%, and annual average copper flotation recovery is only around 50%. A large amount of sodium cyanide, i.e., 5-10kg/t, is required if using CIL …
In fact, the recently announced Ozernoye concentrator plant, processing Zinc, will utilise just 19 Jameson Cells, rather than 63 conventional cells. Not only is this reducing construction by a third, but the footprint of the plant will be less than a half of a conventional plant. More Than 400 Jameson Cell Installations Around The World
MX-7017 is used in the copper-molybdenum plant in Chile which was simulated in this study. In this study, collectors were added directly without dilution while MIBC was diluted to 1 wt% before its use. NaHS (AR grade) was used as the copper depressant in flotation. The pH in flotation was adjusted by 1 M NaOH solution.
