Evaluating Copper Rougher-Scavenger Flotation Circuit

2015. 11. 4.  Liberated grains of galena are about 15% covered into the copper rougher concentrate. Almost all of the remaining liberated galena is recovered in the copper scavenger concentrate. The recovery of liberated grains of sphalerite into the rougher and scavenger concentrate increases linearly with flotation time.

Rougher flotation of copper minerals in columns -

2005. 6. 1.  In this work, rougher flotation of low grade copper minerals (0.6–0.7% Cu) was tested in column cells at laboratory scale. A negative bias regime was used in order to create a levitating effect on particle–bubble aggregates to promote gross particle flotation.

Parametric Optimization in Rougher Flotation Performance

Flotation experiments were conducted in a Denver type agitated flotation cell at the rougher stage. The experimental results showed that increasing the pH (from 8 to 10) at low agitation rate (1000 rpm) enhanced the recovery from 80.36% to 85.22%, while at high agitation rate (1200 rpm), a slight declination occurred in the recovery.

Jameson Cell - Separation Efficiency Improvement of a Low-Grade

2017. 12. 21.  configuration is sequential flotation, where copper bearing minerals are recovered to a saleable copper concentrate, followed by re-activation and flotation of the pyrite which is leached with cyanide to recover gold. Both trains produce a copper concentrate with significant quantities of non-sulphide gangue minerals.

Jameson cell - Wikipedia

The Jameson Cell grew out of a long-term research program aimed at improving the recovery of fine particles by flotation. The work started at Imperial College London, and continued when Jameson moved in 1978 to the University of Newcastle, NSW, Australia, where he is Laureate Professor (2015). Jameson's research into flotation began when he was at Imperial College London, in 1969. A colleague, Dr J. A. Kitchener of the Royal School of Mines, pointed out that many of the new mineral deposits bein

Froth flotation - Wikipedia

Before froth flotation can work, the ore to be treated is reduced to fine particles by crushing and grinding (a process known as comminution) so that the various minerals exist as physically separate grains. This process is known as liberation. The particle sizes are typically less than 0.1 mm (100 µm), but sometimes sizes smaller than 7–10 µm are required. There is a tendency for the liberation size of the minerals to decrease over time as the ore bodies with coarse mineral grains that can be separated at larger sizes a

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 (ε). The experiment was conducted by means of a Jameson cell. The factors influencing the quality of the process were the particle size (d), the flotation time (t), the type of collector (k), and the dosage ...
