The ore minerals are mainly magnetite, containing a small amount of hematite, limonite, pyrite, chalcopyrite and occasionally. Gangue mineral is quartz, plagioclase, hornblende, biotite, followed by calcite, epidote, zircon, apatite and other rare. The useful ore were divided into magnetite, no other significant associated components found. The main purpose of mineral magnetite is black, mostly, euhedral subhedral granular aggregates. The particle size is 0.05 ~ 0.3mm, part of a giant crystal shape, particle size of more than 1mm. A strip, striped nearly parallel arrangement, orientation is obvious, a small amount of disseminated. A small amount of hematite and magnetite with particle size distribution, generally 0.1 ~ 0.50mm; the fracture surface along the limonite ore locally distributed, brown, small grain. The main purpose of the relationship with the mineral hornblende closely is hypautomorphic granular, columnar, and most are magnetite and magnetite with metasomatic filling, banded distribution, particle size of 0.3~0.6mm. Oretype is required to select a weak magnetic iron ore. The test chamber will be iron ore samples from mixing, dividing, sampling with TFe:21.65%, MFe:15.32%.
The entrusted by the owner, through the dry magnetic separation test (magnetic field intensity were 5000, 5500, 6000, 6500, 7000Oe), visits Dongping lianglin iron ore dry polishing feasibility test.
By using the 5500Oe test in the dry polishing, TFe:21.65%, MFe:15.32%, get dry polishing concentrate grade TFe:23.98%, MFe:19.64%, TFe:6.77%, MFe:0.55% grade of tailings dry polishing, discard rate reached 23.42%. Greatly reduce the grinding ore quantity, and provide basic data for the late plant transformation process. In order to make full use of resources, expand production capacity, the purpose of lowering the efficiency.
