distribution in flotation cells is of interest to researchers. Tabosa, Runge and Holtham(2014) investigated the distribution of turbulence and its influence on flotation performance in a 3 m3 flotation cell. They found that the collection zone flotation rate constant can be related to the size of the turbulence zone. By increasing the depth

In the study presented in this paper, the PVS was first applied to a sugary water-air two phase mixture in a 3 m3 pilot flotation cell, and then to a Metso RCS 3 m3 flotation test rig with magnetite/silica slurry and air, to collect turbulence data. An orthogonal experimental design was used for both sets of tests, with different impeller speeds, air flow rates and cell level (aspect ratio) as ...

Analysis Methodology A flotation cell consists of two distinct zones – a mixed pulp zone in which bubbles collide with particles in a liquid phase and a froth zone consisting largely of particle laden air bubbles rising and moving towards the concentrate lip. A proportion of what is recovered in the pulp phase does not report to the final concentrate as it is returned (or lost) from the froth phase. Thus the overall recovery of a mineral in a flotation cell

Flotation Cell Design: Application of Fundamental Principles

One of the most important hydrodynamic conditions in a mechanical Sotation cell is dispersion of gas into Rne bubbles. The bubble generation mechanism in a mechanical cell is a two-stage process. Firstly, air cavities are formedat the trailing edge of the impeller blades, which is the low pressure region.

Froth flotation - Wikipedia

The scavenger cell froth [3] is usually returned to the rougher cells for additional treatment, but in some cases may be sent to special cleaner cells. The scavenger pulp is usually barren enough to be discarded as tails. More complex flotation circuits have several sets of cleaner and re-cleaner cells, and intermediate re-grinding of pulp or concentrate.

Froth recovery measurement in plant scale flotation

01.11.2003  In both cases, the flotation cells were Outokumpu 100 m 3 tank cells in the zinc circuit. Samples of feed, concentrate, tail, air hold-up and top of froth were taken from each of the cells and analysed for percent solids, lead, zinc, iron and silica. The superficial gas velocity was measured at several locations across the cell with the average superficial gas velocity calculated at 1.43 and 1 ...

Both models introduce the reactodseparator concept in their designs and use an extemai in-line air sparger made of porous stainless steel to aerate the pulp. The operating mechanism of the CFC-QI ceIl uses a rotating drum or bowl to create a centrifugai force on the feeding slurry. Froth concentrate is ...

A node can be a single unit such as a flotation cell, a regrind mill or a pump sump, a combination of units (e.g. a bank of cells) or even an entire circuit with the feed being split into the final concentrate and final tailing stream. A node can have multiple input streams and multiple output streams, as in a flotation cell with multiple feed streams, or a single input and single output stream, as in a regrind unit. (a) (b) (c)

04.11.2016  Runge is working on a number of research projects. Progress made by equipment manufacturers notwithstanding, she thinks there is much more to understand about how turbulence affects flotation in the bigger cells. “A lot of people have just changed one variable and seen correlations and made conclusions from that,” she said.
