The purpose of the test is to provide the most reasonable beneficiation process and economic indicators for the mine through mineral processing test, which provides a reference for resource development and utilization.
Identified by the identified rock, the main mineral of the iron ore is a titanium ore magnetite, ilmenite, and a small amount of pyrite gangue minerals pyroxene, hornblende, amphibole times, epidote or zoisite , chlorite, etc.
Titanium magnetite is mostly self-shaped - semi-self-shaped - he appears in granular form, the particle size is generally 0.05 ~ 1mm, mainly concentrated in 0.1 ~ 0.6mm. The magnetite is distributed in the ore in a non-uniformly disseminated state, and is mostly distributed among the gangue mineral particles, and is partially contained in the gangue minerals, mainly composed of independent monomers, and also sees the occurrence of twin polymerization.
The content of ilmenite is relatively low, about 1~3%, and there are two stages of ilmenite. The early ilmenite is mostly sheet-like, often etched into odd shape, with fine grain size, generally 0.01~0.3mm. It is distributed in the cleavage of gangue minerals or between grains; the late ilmenite has a coarse grain size, generally 0.5~0.8mm, mostly granular or irregular granular, with pitting inside.
Tonghui stone and hornblende are the main gangue minerals. The brown color of the pyroxene belt indicates that the pyroxene contains a high amount of titanium, and the altered product has many titanium-containing minerals such as vermiculite. The pyroxene should be mainly composed of titanium. The gangue mineral, which is a mineral transformed from pyroxene, inherits part of the titanium from the pyroxene. Due to its high content, it should also be an important titanium-containing gangue mineral other than pyroxene.
It can be seen that the minerals that can be recovered from the mine are iron minerals. Because most of the titanium-containing minerals are symbiotic with gangue minerals, the recovery of titanium minerals is difficult.
In this test, a weak magnetic field magnetic separation was used to obtain a product with an iron concentrate grade of 65.94% and an iron recovery of 64.38%.
Titanium minerals are not enriched by strong magnetic separation, re-election, and flotation.
