Brife introduction:

Our High gradient magnetic separators utilize the combined forces field of magnetism, pulsating fluid and gravity to continuously beneficiate fine weakly magnetic minerals. They possess the advantages of high efficiency, low operative cost and high reliability. Till now there are about 600 high gradient magnetic separators widely applied in processing oxidized iron ores, ilmenite, manganese ore and many other minerals.

 

Application and advantages:

High gradient magnetic separators beneficiating low-grade iron ore possesses the advantage of low cost and big capacity. They can be applied in the roughing stage to discharge most tails and slimes, upgrading the rough iron concentrate to a higher level, to make good condition for reverse-flotation.

 

(1) High gradient magnetic-reverse flotation flowsheet is simple and can get good iron concentrate grade and recovery. But usually the iron grinding size is fine and grinding energy consumption is more than other flowsheet.

(2) High gradient magnetic-gravity-reverse flotation flowsheet possesses the advantages of that coarse liberated iron ore can be recovered by spirals and part coarse tails can be discharged by High gradient magnetic separators (0.2~0.6T) at the primary stage. Only part of fines enters the High gradient magnetic separators (1.0T)-reverse flotation stage. This flowsheet can get good iron concentrate grade and recovery with low cost, but the flowsheet is more complex than others.

(3) Pure High gradient magnetic separation flowsheet to treat oxidized iron ores possess the advantages of simple, low cost, good iron recovery. But iron concentrate grade is usually not high enough.

(4) High gradient magnetic-gravity flowsheet to treat oxidized iron ores are simple and low cost. But iron recovery is usually not high enough.

(5) Many Chinese iron ore deposits are of low grade. High gradient Vertical ring pulsating high gradient magnetic separators have become the most advanced high intensity magnetic separator in such iron ore processing industry in China, promoting the oxidized iron ore processing technology developing fast.
