copper concentrator rougher flotation feed showed retention time gains on the order of 6 to 9 times when compared with conventional flotation equipment. This finding has the potential of reducing capital demands for rougher flotation circuit designs when incorporating the StackCell. The results from test …
In this work rougher flotation tests were conducted with two copper ores at laboratory flotation scale under standard industrial conditions, and Cu and Mo recoveries were calculated as a function of pH with sea water and tap water.
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
Both samples were coarser than standard granulometric size used in conventional rougher ﬂotation. A series of eight tests, in duplicate, were carried out with sample a. The conditions and metallurgical results are shown in Table 1. If tests 1 and 2 are compared, it can be seen that air ﬂow improves Cu recovery.
82% Au by 6-stage rougher flotation. Although finer grinding improved the copper recovery, primary grinding to a 80% passing size (P 80) of 150μm was the indicated optimum target with regarding the energy consumption in the comminution processes. The tests reveal that the mineralization type has substantial influence on the
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.
This is why rougher and cleaner rate tests should be performed for MF1 and MF2 conditions. Flotation kinetics are derived from Kelsall's unmodified equation and comprise fast and slow floating fractions and rates of metal and/or mineral and gangue. Together, these variables define a flotation system, whether in the laboratory, pilot plant or

This paper provides an overview of the effects of reducing the pH in the EHM copper rougher flotation circuit. The pH in the roughers was dropped from 10.6 to 9.6 to determine the impact on the rougher performance and the subsequent performance of the whole copper flotation circuit.
KYF air inflation floatation cell has U tank floatation cell and column flotation cell which is composed of impeller, stator, main shaft, bearing body, air adjusting valve, and tank body, as picture shown .. KYF air inflation floatation cell is applied in roughing and cleaning of large and middle scale dressing plant aiming to non-ferrous metal, ferrous metal and nonmetal minerals.

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
scavenging flotation, while the-48 fraction is discarded. This rougher-scavenger flowsheet achieved excellent results on lab scale, but required fine tuning of fatty acid dosage in rougher flotation. In flowsheet #3, the flotation feed is first sized at 48 mesh (or somewhere between 35 and 48 mesh). The coarse feed is subject to one-step flotation,
The bench-scale flotation tests were performed in XFD-63 flotation cell (self aeration) whose volume for rougher flotation was 3.0 dm 3, for separation flotation of copper/iron sulfide minerals was 1.0 dm 3 and for cleaner flotation was 0.5 dm 3, respectively.
Pyrite-Gold Recovery in Copper Rougher Flotation Tailings. at the head of copper flotation (copper rougher feed) and after regrinding of the copper rougher tailings, before gold/pyrite selective flotation. ... However, when the copper rougher tails (Test 1, Test 2 and Test 3) were reground, only 25% of the total gold lost was recovered in Test 1.
Copper–molybdenum ores ﬂotation in sea water: Floatability and frothability ... Laboratory rougher ﬂotation tests were conducted with two samples of Cu–Mo ores in fresh water and in sea water as a function of pH. In both cases Cu recoveries were slightly lower in sea water than in fresh ... 2.2.1. Flotation tests
A total of four cleaner flotation tests were conducted. Rougher flotation concentrates were collected and transferred in to a batch floatation cell for cleaner flotation. Concentrate samples were retrieved at timed intervals and sub-samples were submitted for analysis to determine the grade recovery profile of each test…
