Porphyry copper deposits are important sources of copper and typically processed by flotation to produce copper concentrates. As mining areas become deeper, the amounts of impurities, such as sphalerite, can be increased in copper ores, so the appropriate depression of sphalerite floatability should be achieved to obtain saleable copper concentrates. In this study, the …
Predicting the metallurgical performance of a flotation cell can be done using kinetics testing and mathematical modeling. Since its introduction in 1985, the so-called compartmental model of flotation has been adopted by most modeling and simulation platforms [4, 5].This model separates the flotation cell into two zones, each with its own sub-model.

Flotation behaviour in reflux flotation cell – A critical review. 1. Introduction. With the continuously high demand for energy and metals around the world, high-grade ore deposits are sharply depleted (Peng and Bhambhani, 2021).This forces the industry to transition into the processing of complex and lower grade ores (Mudd, 2010).As ore grades decline, more challenges arise in …
Copper recovery improvement with performance-based flotation cell retrofit at Antapaccay Glencore's Antapaccay is a mining and processing operation producing copper concentrates in Peru. Annual copper production from the mine is expected to be 160,000 tonnes in concentrate form. Antapaccay's flotation circuit was commissioned in 2012.

application in several flotation systems. MEASURING THE PULP KINETICS. The traditional approach to flotation scale-up testwork attempts to use . a batch cell to replicate industrial performance, assuming that the lab cell works as a scale model of the full plant. Industrial experience has shown, unfortunately, that the results obtained

Asghari et al. [27] investigated the improvement of copper recovery in an industrial flotation circuit (Sarcheshmeh copper mine), and stated that about 95% of overall copper lost in final tailing was in the rougher circuit while the rougher flotation recovery of …
The Jameson Cell The Jameson Cell is a high intensity flotation cell in which pulp and air are brought together in a co-current descending flow in a vertical tube called the downcomer. The pulp is introduced into the downcomer through a slurry lens orifice to produce a high velocity jet that generates violent mixing and fine bubble size.

In addition to recovery of valuable minerals, the flow sheet for this iron oxide-hosted copper-gold deposit has to address the issue of producing a good quality saleable copper concentrate by …
Different milling conditions, such as wet or dry, and use of different grinding media have a great impact on the flotation performance of sulphide minerals. In the present study, the effects of wet and dry grinding and the use of different grinding media, such as mild steel (MS) and stainless steel (SS), were investigated on a Cu-sulphide ore. The samples were ground as …
A maximum recovery of copper was 88,58% while the grade was 2,88 with 32,29 copper oxide on the total massive copper under the flotation conditions: 1,15 pulp density, 10 g/t dosage collector, 10 g/t dosage frother, and 50 g/t dosage dispersant and the maximum grade 12,24 while the recovery was 47,02% under the flotation conditions: 1,15 pulp ...
Conventional flotation plant optimization procedures for copper and copper–gold ores have served the industry well over decades.
