Iron Ore Beneficiation Plant

Details of this product

Abstract: There are many types of iron ore, iron ore beneficiation plant different there are some differences, this article will be a single weakly magnetic iron ore, for example, talk about the weakly magnetic iron ore beneficiation plant. Hope it will be useful for you.

Single Magnetic Iron Ore

Single weakly magnetic iron ore, including hematite sedimentary-metamorphic, sedimentary, hydrothermal and weathering type deposits, diamond ore, limonite iron ore and hematite (iron mirror) – Ling iron ore. Such Iron Ore Beneficiation Plant practice less, due to the mineral species, widely disseminated size range, Iron Ore Beneficiation Method used is also more commonly used methods can be divided into two types;

Single Weak Magnetic Iron Ore Beneficiation Plant

Magnetization roasting or re-election, flotation, magnetic separation and strong parallel plant. Roasting is sorting fine to fine particles (<0.02 mm), one of the effective methods weakly magnetic iron ore. When the ore mineral complex, difficult to obtain by other means good indicator, you should use the magnetization roasting method. 75 to 20 mm of lump ore roasting reduction shaft furnace has a long experience in the production; less magnetization roaster production practices 20 mm or less fine ore. Currently, ore powder commonly used high intensity magnetic separation, re-election, flotation line method or combined flow sorting.

Re-election, flotation, magnetic separation or strong joint plant. Flotation is the sorting of fine particles into one common method of weakly magnetic iron ore. There are two kinds of principles of flotation and reverse flotation plant. The former applies to float free and easy gangue of quartz hematite, which applies to ore gangue easy to float, have production practices.

Iron Ore Beneficiation Equipment

Re-election and the strong magnetic mainly used for sorting coarse (20 to 2 mm) and medium-grained weakly magnetic iron ore, since these two methods in recent years, considerable progress technically, China has begun to use in the sorting of fine weakly magnetic iron ore. Coarse and very coarse (> 20 mm) of ore re-election commonly used medium or heavy jig beneficiation; into the fine ore spiral concentrator, shaker, fan-shaped chute and centrifugal concentrator methods such as flow membrane re-election, coarse, strong magnetic ore used in dry grain roll strong magnetic induction machine; fine ore used temperature sensing medium intensity magnetic separator. Currently, due to the strong magnetic fine ore concentrate grade is not high, but lower unit planting capacity re-election, so often composed of magnetic – re-election joint plant, a large number of qualified tailings discarded by strong magnetic separation, and then re-elected for further magnetic concentrate planting to improve taste.
