flotation cell with less machine stop time

Until only a few years ago mechanical flotation machine capacity was limited to eight to 15 tons of ore per running foot per 24 hours and this meant that a “small” 10000 TPD mill needed in the neighborhood of 150 rougher cells while a 30000ton mill would need about 500 rougher cells

This particular ore does not with the normal flowsheet produce an acid grade concentrate of 975 CaF2 with less than 15 SiO2 ” The ore being studied is crushed underground at the mine and partially beneficiated by the heavy media process This washed ore is further crushed at the mill

Making flotation cells work 48 replies For a number of years a mine struggled to float a sulfide mineral and was getting less than 50 recovery even after installing a rotor and stator “upgrade” We did minor modification to the rougher float cells and achieved a 19 increase in recovery

This was confirmed by our unsuccessful attempts to modify a two cell No 5 Denver “SubA” mechanical flotation machine The fixed speed impellors 1400 rpm did not provide sufficient agitation Modifications could only increase the speed to 2000 rpm which was again not sufficient to maintain suspension

Considering your load cells response time The load cells response time is another factor to consider for some applications The typical load cell behaves like a stiff spring that oscillates so to achieve an accurate weight reading the load cell must settle that is stop oscillating in less time than the required weighing period

The Davcra cell Figure 1281 was developed in the 1960s and is considered to be the first highintensity cell could be thought of as a column or reactorseparator device Air and feed slurry are contacted and injected into the tank through a cyclonetype dispersion nozzle the energy of the jet of pulp being dissipated against a vertical baffle

A Wemeco Fagergren machine with a 2 litre cell was used Recoveries were somewhat inconsistent but it seemed more suitable for well sorted or deslimed feeds such as beach sands Subsequent clientfunded work confirmed this with consistently high recoveries over 80 and low mass yields less

O with 959 recovery Operationally an optimum flotation of 30mesh sylvinite with the indicated amine and MIBC dosages at the agitation intensity of 1000 rpm and 9minute conditioning time yields 391 K 2 O with 942 recovery Furthermore the flotation kinetics follows the firstorder rate law with rate constant of 141 sec1 Suggested
