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.
(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.
High gradient magnetic separator application:
Black metal: To recycle feint hematite, hematite, limonite,
siderite, ilmenite, manganese, etc.
Nonferrous metal: To separate wolframite, garnet, etc.
Rare metal: To recycle tantalum niobite, iron lepidolite, monazite,
xenotime, etc. Nonmetal: Purification of impurity from quartz,
feldspar, kaolin and refractories material.
