Thus in an ore containing both sulphide and oxide copper the recovery credited to the process should be based on the sulphide copper content of the feed, concentrate and tailing, if a true measure of the efficiency of the process is sought. ...
Flotation data for the design of process plants Part 1 – testing and design procedures R. C. Dunne*1, G. S. Lane2, G. D. Richmond3 and J. Dioses2 This paper discusses the methods used in the design of flotation plants, including benchscale batch and locked cycle tests and pilot plant trials. The methods used to establish appropriate
Ion flotation is an efficient separation technique for the recovery of metal ions from dilute aqueous solutions. Provided that both the collected metal and the surfactant are recovered from the phase, it could be considered as an alternative to ion exchange, adsorption or solvent extraction in hydrometallurgy. However, most studies …

When liberation problems are part of the ore's characteristics the designers of the concentrator plant will include a REGRIND MILL in the Basic Flotation Circuit Design of its flow sheet. A regrind mill is precisely that, a mill that grinds the material again after it has been concentrated at least once.
The Mineral Processing Flowsheets shown on the following pages are based on actual data obtained from successful operating …
In some cases, high recoveries of gold by flotation are accompanied by high levels of pyrite flotation, resulting in a low-grade copper concentrate for treatment. Smelting of low-grade concentrates incurs significant economic penalties in shipping of concentrates to smelters, unit deductions in smelter contracts and treatment and refining …
Three factors were measured in the flotation process of copper ore: the copper grade in a concentrate (β), the copper grade in tailings (ϑ), and the recovery of copper in a concentrate...
In the current work, we investigated a methodology to assess the potential energy savings when a fluidised-bed separator (i.e., the HydroFloat) is incorporated into a conventional flotation...
After carrying out a froth flotation separation, the products are as shown in Table 1. Using this data, calculate: (a) Ratio of concentration (b) % Metal Recovery (c) % Metal Loss (d) % Weight Recovery, or % Yield (e) Enrichment Ratio Table 1: Grade/recovery performance of a hypothetical copper ore flotation process.
There are different methods of processing copper mines, such as preferential flotation, bulk-separating flotation, etc. for copper sulfides, and sulphidizing flotation, fatty acid flotation, etc. for copper …

The following tabulation shows the character of the flow-sheets, on the basis of the classification presented, at representative concentrating plants. Several of …
flotation testing, with back-up quantitative mineralogy to confirm the validity of the conceptual flow sheet. Detailed chemical assays were done on the copper concentrates. • Copper-gold breccia flow sheet development – G&T: this was an extension of the flow sheet confirmation and included examination of the following:
MMG Kinsevere HMS plant flow sheet (After Booth et al., 2010). ... insoluble: max 0.01%) is used as a depressant of blende in the flotation of copper-zinc-bearing ores.-Senfroth G41 (≈10 g/t) is used as a frothing agent for the flotation of sulphides and oxides by sulphidisation. 3.2.3. Flotation of Cu–Co ores
The recovery of these copper minerals by flotation or hydrometallurgy from ores, typically containing 0.5%TCu (open pit mines) and 1-2%TCu (underground mines) is of great commercial importance ...
The processing of gold copper and copper gold ores can be highly problematic, site specific and the process selection is dependent on ore grade, mineralogy, acid leach …
Copper Sulfide Flotation Circuit Beneficiation of Copper Sulfide by Flotation Copper, due to the present world demand and price, is of foremost interest to the mining industry. Many new properties are either in the process of being brought into production or are being given consideration. Copper minerals usually occur in low grade …
