Middle Duty Flotation Cell Concentrate

Nov 01, 2009 The selection of the size, number and type of flotation cells for a particular duty depends on two important factors. These are the required flotation residence time and the physical constraints of how much concentrate can be recovered for a given froth surface area and concentrate

Flotation cells for profitable minerals concentration

The basic module of the Wemco 11 flotation system is a cell consisting of a single tank and mechanism. Several cells are bolted together to form a flotation machine with feed, connection and discharge boxes as required. Pulp level in the tanks is controlled by automatically operated dart valves in the connection and discharge boxes.

Flotation launder design and the measurement of critical

Description. In flotation, the selection of the size, number and type of cell for a particular duty depends on two important factors. Firstly, the required flotation residence time and secondly, the physical constraints of how much concentrate can be recovered for a given froth surface area and concentrate

From its first Wemco 257m3 cell installed in 2003, to now even bigger 300m3 cells being installed in Chile. These 26 x 300m3 Wemco cells will be the first major installation of 300s for a new plant and the first used in rougher ...

Flash flotation equipment design AusIMM Bulletin

Flash flotation is the rapid flotation of mineral particles to produce a suitable concentrate. Normally, the feed to a flash flotation cell is the cyclone underflow stream. The aim when treating cyclone underflow is to recover liberated fast-floating mineral particles before they present back to

Flotation Machines amp Flotation Cells

The computational basis assumes 30 percent solids in rougher flotation, 20 percent solids in cleaner, recleaner and cleaner-scavenger flotation, a ratio of concentration in rougher flotation of 3.07 an overall ratio of concentration of 5.0, and an ore specific gravity of 2.9.

Selecting Flotation Cells How Many and What Size

These notes were contributed by Peter Bourke, Manager, Flotation Cells, for Outokumpu Technology Pty Ltd. He has more than a decades experience at the leading edge of the development of flotation cells, having been involved successively in the installation of Outokumpus first 100, 150 and 200 cubic metre float cells.

Pneumatic Flotation Challenges Conventional Technology E

Column-flotation technology does not use an agitator, with the feed being introduced from the middle of a deep tank by gravity, and air being injected from the bottom of the cell with the help of a compressor. The particle-air collision time in a single cell is very low, so selectivity is very high. Multiple cells are used to get an acceptable ...


management solution that maximizes your flotation cell performance and gives you greater metallurgical control with the optimal lip length, froth area, and transportation distance for the specific cell duty, plus robustness for feed grade and capacity changes. The FloatForce

SkimAir flash flotation unit Outotec

Employing flash flotation in the circulating load has also been shown to stabilize the flotation feed grade to the main circuit. Tough flotation duty handled by smart technology Since Outotec first implemented SkimAir technology in the 1980s continuous technological improvement have made it the worlds leading Flash Flotation technology.

WEMCO 11 Flotation Machines

cell technology with the greatest installed capacity of any flotation manufacturer. Unique Flotation Mechanism At the heart of each 11 cell is a patented rotor-disperser that delivers intense mixing and aeration. Ambient air is drawn into the cell uniformly distributed throughout the pulp, providing optimum air particle contact.

Effect of frother addition mode on coal flotation in

The vapor addition mode of frother presents a faster concentrate recovery in the middle 1.5 min flotation time and a higher flotation rate of cleaner coal product as a whole as compared with the liquid addition mode. Download Download high-res image 126KB Download Download full-size image

Flash flotation an introduction AusIMM Bulletin

The second main benefit when using flash flotation is that the cell acts in a scalping duty, so feed grade variations in the cyclone overflow stream for the downstream circuit are evened out. In ores where the valuable minerals have a much higher specific gravity than the gangue minerals eg most sulphide ores, PGM, gold ores the ...

Flotation Archives Page 14 of 30 Mineral Processing

The result is a higher grade concentrate with better recovery. These flowsheets show regrinding the middling, preventing the retention of middling in the flotation circuit or its loss into the tailing. After regrinding, the freed mineral floats rapidly and is recovered successfully in the finished clean concentrate.


The flotation plant design was based on extensive benchscale testwork including locked cycle tests on drill core and many months of operation of a 30 tonne per hour pilot plant using the old Cleveland Tin Mine process plant, modified for the duty. The Cadia concentrator was designed on an extensive benchscale variability testwork

Flotation Cell Control International Mining

flotation duty i.e rougher, cleaner etc, changes are generally small and infrequent. A flotation circuit where the slurry level is subjected to large or frequent changes is usually going to be in a constant state of flux as the changes in one cell will impact other cells in the circuit.
