Jameson cell coal flotation (Book) | OSTI.GOV

Some coal mines have Jameson cells in operation, some are having Jameson cells installed and others are considering to use Jameson cells in their flotation circuits. As an example, the application of Jameson cells in Newlands Coal Mine is described and the performance of the Jameson Cell is summarized.

When the feed contains liberated, fast floating mineral particles, the Jameson Cell produces final grade product reducing the number of cells required for downstream processing. The recovery in one Jameson Cell is usually equivalent to several mechanical cells. Pre-cleaning (scalping) duties where the Jameson Cell recovers the fast floating minerals …

Reverse column flotation of iron ore | SpringerLink

Two-stage flotation with the columns could produce a concentrate that was up to 70.2% Fe at 87.5% iron recovery, compared to 70.4% Fe at only 77.7% iron recovery for four stages of flotation in conventional cells. It was shown to be particularly important to operate the columns to recover a maximum of the quartz gangue into the froth.

Jameson cell - Wikipedia

Jet flotation, also referred to Jameson cell technology, involves the generation of small bubbles through high mixing, leading to faster recovery. Compared with other flotation methods, dispersed ozone flotation is a little bit different because the air commonly used to generate bubbles is replaced by ozone.

How It Works

The Jameson Cell consistently produces fine bubbles and intense mixing between air and slurry. This means fast, efficient flotation. While the principle of using air bubbles to recover particles is the basis of the technology, it is the way air bubbles are generated and how the bubbles and particles interact that make Jameson Cells unique.

The Use of the Jameson Cell to Improve Flotation Circuit ...

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.

Design Developments of the Jameson Cell

Since Jameson Cell flotation technology was first installed in a coal flotation application in 1988/89 at Newlands Coal Handling and Preparation Plant (CHPP) there have been fundamental improvements to its design which has led to its current status as the leading technology in Australia for fine coal flotation. These improvements, which include key hardware …

the cell. Many cells also employ a beveled edge along the bottom of the cell. This forces particles towards the rotor, and prevents the buildup of sediment on the cell floor. Column flotation cells have a high height-to-diameter ratio, as shown in Figure 2 on the following page.

CONCENTRATION Graeme Jameson

The Jameson Cell is a radically different flotation device that changed the way that minerals were recovered and earned Jameson almost legendary status in mining and engineering circles. With cells now in operation across more than 25 countries, it is being used for copper, coal, zinc, nickel, lead, silver and platinum extraction worldwide.

Multidimensional Optimization of the Copper Flotation in 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 …
