The over-riding principle in ore washing is to provide sufficient energy and time to detach the fine clays but not enough to cause comminution of the intrinsic particles to smaller components. Care also needs to be exercised to provide appropriate energy and flow to maintain the fine …

The dynamic wet scrubber is equipped with a monitor for differential pressure, liquid flow rate, and fan amperage. These parameters can be continuously monitored from the CMS. During the inspection, the ore dryer was not in operation and neither was the wet scrubber with the fan amperage reading 0 amps. Testing/Sampling

For easy-to-clean ore, the scrubber should use a lower speed (3o% – 4o% critical speed), for the haigh plastic clay ore, the scrubber should use a high speed (70% ~ 80% critical speed).

We changed the compliance date for monitoring requirements for fan amperage on dynamic wet scrubbers from 180 days after promulgation of the final rule to 18 months after promulgation of the final rule for taconite iron ore processing facilities that operate dynamic wet scrubbers and have been monitoring their operation using pressure drop and ...

ores because of depletion of high-grade iron ore. The low-grade ores are highly contaminated with alumina — 7 to 8 percent — and silica — 8 to 9 percent — and demand new beneficiation techniques to make them usable. The advantage of wet washing circuits is limited to the partial removal of adhering alumina and silica in the iron ore.

The scrubber is acting as a light autogenous mill and mill selection criteria can become important, particularly when power input is greater than 0.5 kWh/t (David, 2003). Under these circumstances it is important to consider the kW/t of coarse ore as a scaling factor in the capacity of a scrubber.

The category includes, but is not limited to, the following processes: Liberation of the iron ore by wet or dry crushing and grinding in gyratory crushers, cone crushers, rod mills, and ball mills; concentration of the iron ore by magnetic separation or flotation; pelletization by wet tumbling with a balling drum or balling disc; induration ...
