Iron fine powder beneficiation process: In the steel sludge wet magnetic separation iron fine powder process method is to put the steel sludge into the slurry tank, the first water immersion, and then impact the steel sludge with high pressure water and add the appropriate water to make the steel mud to the rule fineness, steel mud through the slurry pool in the screen is transported to the magnetic separator material box, at the moment magnetic separator iron fine powder and tailings, The fine iron slurry flows into the dewatering tank for dehydration and storage, and the tailings slurry is discharged into the tailings pit. This method can completely recover the iron fine powder in the steelmaking sludge, so as to achieve the maximum utilization of resources.

Detection methods and technical status

According to the physical and chemical properties of iron powder. At present, there are three detection methods that can detect iron fine powder raw materials: neutron, near infrared and microwave.

Each of these three methods has its advantages and disadvantages.

Neutron method

Advantages: it does not affect the normal running state and structure of the sample;

Disadvantages: The neutron must be manually calibrated, but the neutron itself has radiation, radiation license application and personnel protection investment is high, the accuracy is greatly affected by density, measurement volume;

Near infrared spectroscopy

Advantages: continuous, non-contact detection, fast measurement speed and suitable for online detection;

Disadvantages: It is affected by the shape, density, thickness and light of the sample and the cleanliness of the surrounding environment. It can not detect the internal moisture of the substance.
