Section 2 bulk rougher stage also consists of three parallel lines two of the lines equivalent to the flotation lines in section 1 and one line consists of 13 cells with a net volume of 38 m 3 resulting in a total flotation capacity for the full section of approx 1513 m 3
Eric bain wasmund eriez flotation divisions global managing director explained that large mechanical cells are the mainstay for rougher flotation in almost all bulk flotation processes increasing the individual cell size and reducing the number creates modest improvements in footprint and operating costs but it doesnt improve the

For a testwork laboratory treating a wide variety of ores the most useful laboratory flotation machine is probably one with cells of 500 1000 and 2000g capacities with a different diameter impeller for each cell with stainless steel or rubbercovered impellers glass or follows once acceptable recoveries are attained in the rougher float
Conventional flotation cells allow a small amount of clay slimes to be recovered with the water that reports to the froth product a column cell fig 19 virtually eliminates this problem by washing the clay slimes from the froth using a countercurrent flow of wash water this feature allows columns to produce higher quality concentrate coals
A flash flotation cell is designed differently to a conventional mechanical flotation cell as it operates at higher pulp densities than conventional flotation cells the cyclone overflow grade to be more consistent and allows plant operators to optimise the use of reagent and rougher cell
The goals for the rougher area are to maximize recovery maintain acceptable rougher concentrate grade and to minimize reagent consumption flotation overload recovery strategy 1st high sump levels evaluate the rougher concentrate sump level and lower pulp levels when the sump level is
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 8036 to 8522 while at high agitation rate 1200 rpm a slight declination occurred in the recovery
From the upper part of the cell by the rotor figure 1 large flotation cell experimental tests were developed in an industrial rougher flotation circuit consisting of 4 parallel banks each one provided with 7 cells of 130 m3 figure 2 shows the flotation banks arrangement figure 2 flotation banks arrangement 21 tracer technique
The air demand for the old rougher cells for example was estimated at over 3000 am3h whereas the estimated air demand on the outotec tankcells is a maximum of 992 am3h the outotec floatforce rotorstator mechanism with its unique design delivers enhanced flotation cell hydrodynamics and improved wear life and maintenance
Dec 02 2014 while the rougher concentrate from the last two cells goes through a cleaner flotation step the amine study phase vi investigated the performance of six types of amines primary secondary tertiary quaternary ether and condensate on the cleaning step of the rougher concentrates or the crago process and the effect of particle size on thef
Mechanical cell and a flotation column kinetic data obtained from bench mechanical flotation machines generally is not easily applied to column sizing the quantity of rougher feed required to generate sufficient rougher concentrate for column pilot testing is generally too large to justify a pilot plant however the selectivity that is

The existing section 1 bulk rougher lines consist of three parallel lines of 18 cells per line with a total flotation capacity of approx 1529m 3section 2 bulk rougher stage also consists of three parallel lines two of the lines equivalent to the flotation lines in section 1 and one line consists of 13 cells with a net volume of 38m 3 resulting in a total flotation capacity for the full
Metso rcs flotation machines also are found as an essential piece to a regrind circuit rougher cells extract majority of the valuable mineral from the fresh ore meanwhile scavenger cells are going to capture the remaining valuable mineral
Nov 04 2016 the stages might run coarse grind preconcentration flotation grind rougher flotation regrind and cleaning flotation gorain agrees that it could potentially be of use nonflotationbased preconcentration is actually much more attractive because youre trying to deal with the waste right in the mining before any major energy
Nov 01 2011 the overall flotation circuit was not performing at optimal rate due to entrainment problems in the rougher cells when feed density increased from 45 to 55 solids typically at 105 th
Froth recovery measurement in plant scale flotation cells the new froth recovery technique was used to measure froth recovery in a rougher and scavenger application in both cases the flotation cells were outokumpu 100 m 3 tank cells in the zinc circuit samples of feed concentrate tail air holdup and top of froth were taken from each of the cells and analysed for percent solids lead zinc iron
Flotation duty ie 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 pump hoppers overflowing
Rule 4 i need at least 4 control stages in the flotation cell train to provide circuit flexibility a control stage is defined as a cell or cells which operate with a common level control many people use the term cell bank to define this group of cells
This information together with the concentrate mass flowrate allowed the estimation of the froth recovery of floatable mineral in a 130 m3 rougher flotation cellit was found that mineral
Flotation feed density is an operating parameter which is currently not well understood most models of flotation only incorporate its effect on particle residence time but it is likely to have
The rougher and scavenger concentrates may be reground to a predetermined liberation size and then subjected to two or three stages of cleaner flotation to produce a final flotation concentrate cleaner flotation tailings is an intermediate product and is recycled within the flotation circuit
In the case of highly oxidised coal twostage flotation may be required to be incorporated with rougher cells and cleaner cells the circuit consists of a number of banks depending upon the total quantity to be handled whereas each bank can have four to eight cells for smooth operation of the system proper operation and control are necessary
A project in which an entire concentrator was converted from mechanical flotation cells to column flotation cells over a period of 2 years as part of a program to reduce plant operating costs for complete details download the paper below industrial applications of column cells as roughers
