concentrate launder lip length for platinum flotation cells

Dec 14, 2015 · The froth collects at the top of the cell and is scraped by a revolving paddle over the lip at the side into the concentrate launder. The pulp, containing the gangue and any mineral particles not yet attached to bubbles, circulates to some extent through the zone of agitation, but eventually passes out through a slot situated at the back of the

May 27, 2015 · The nature of concentrate (or product) removal is similar with most of the mass in coal flotation generally recovered in the first 1-2 cells. Figure 1 …

flotation cells: selecting the correct concentrate launder

Jan 12, 2010 · Central donut launder Internal peripheral launder External double launder External peripheral launder Radial launder . 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 …

concentrate launder design: what is right for your

Oct 13, 2009 · This design, however, provides more froth surface area. The external peripheral launder does not consume cell volume, so the effective cell volume for flotation is also higher. This launder is predominantly used on smaller TankCells. The external double launder includes a second internal launder, providing added concentrate lip length. This

designing flotation circuits for high fines recovery

May 01, 2006 · Mt Isa and MRM successfully float more fines than any other sites, and we use a range of different flotation equipment—flotation columns, Jameson cells, several different makes of conventional cell. Our selection criteria for flotation cells has been on the basis of • Ensure adequate residence time. • Ensure adequate lip length. •

flotation launder design and the measurement of critical

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 lip length. The residence time is influenced by ore type and characteristics such …

flotation froth management upgrade - metso outotec

There are limitations to the volume of material the froth phase can support and transport to the flotation cell’s launder lip in any given period. This is known as the froth carry rate (FCR), and is expressed as t/m²h, or the amount of material that 1 m² of froth can carry to the launder lip …

flotation process audit and bottleneck identification

Jun 14, 2017 · Flotation cell concentrate can be sampled directly from the cell launder with a lip sampler. The lip sample can be timed and, based on the time, it is possible to estimate the sample dry weight, the lip length, the length of the sampler and the mass pull of the cell

eliminate flotation bottlenecks | e & mj

The cell’s froth surface area and lip length must be designed to match properties, such as particle size, froth stability and concentration flow rate. For example, a high concentrate flow rate and stable flowing froth will require more froth surface area and lip length to handle the higher flow

modelling of froth transportation in industrial flotation

It should also be noted that, in industrial flotation cells, there is always a significant portion of the froth burst on the surface of the cell and not reporting to the concentrate launder
