The feed pulp is distributed and flows by gravity into four parallel banks of No. 24 (43×43) "Sub-A" Flotation Cells, comprising two 10 – cell machines in each bank, for a total of eighty cells. Distribution and flow through the cells is shown on the accompanying flowsheet. Details
Rougher or middling product can be returned to the front or back of any cell by gravity without the use of pumps or elevators. Cells can be easily added when required. This …
The requirement for higher quality pellets demands that the silica content be lowered to levels ranging from 0.25% – 2.0% SiO2. Reverse flotation (silica is floated away from the iron concentrate) has proven to be an economical and effective method for reducing the concentrate silica content to very low levels.

That is followed by both low- and high-intensity magnetic separation (LIMS and HIMS) to not only remove iron minerals (mostly hematite, Fe 2 O 3) for feeding to the iron flotation cells but, more importantly, to preconcentrate the REMs (mostly bastnaesite and monazite) as feed to the REE flotation circuit and produce a rougher REM concentrate ...
Flotation cells are mechanical equipment that bring the ore in contact with air, water, and chemical agents. Their main function is to separate the previously conditioned slurry into a concentrate and tailings. The level of these cells is …
In fact, every sink-float plant on the iron range uses these Allis-Chalmers screens for this job! Some of the reasons: … Granulair Technologies – Vibrating screen
conditioning tank, collector conditioning tank, and two float cells essentially forms a CPS stage. The whole bank of six cells and two sets of conditioning tanks results in residence time of around 25 minutes. The rougher and scavenger concentrates produced are further treated to match the requisite final concentrate grade at a minimum of 25% ...
The conditioned and pH-adjusted aqueous coal slurry is aerated in a conventional flotation machine or bank of rougher cells ... flotation cell used is a Galigher ... In the flotation cells manufactured by The Galigher Company of Salt Lake City, …
Iron ore tailings valorization through separate. Figure 9 compares iron grade and yield of the magnetic separation concentrate of the Cobber, Rougher, and total tailings by the wet drum-type low intensity magnetic separator at magnetic field intensity of 3500 Gauss, the pulp solid content of 30%, dry feed weight of 1 kg, and drum rotating speed of 40 rpm.
i ABSTRACT Production of platinum and associated metals is a major source of revenue for South Africa. Significant losses occur in the concentrating stage (10 to 15 per cent) and this research is

Improved metallurgical performance of column cells in iron ore flotation is reported and attributed to froth washing, which reduces the loss of fine iron minerals entrained into the froth phase (Dobby, 2002). The Brazilian iron ore industry has embraced the use of column flotation cells for reducing the silica content of iron concentrates.
