Magnetite Separation Production Line
Introduction: Magnetic separation places the leading position in iron ore separation. For weak magnetic and lean iron, Xinhai adopts gravity separation, magnetic separation, flotation, and roasting magnetic separation; used for strong magnetic iron ore, magnetic separation.
Application: Magnetite Separation Production Line is used to single magnetite with simple ore properties.Descriptions:
Strong magnetic iron ore separation process
It is used to low grade magnetite. Due to the strong magnetic and easy to grind, one stage grinding is adopted for magnetite with coarse particle distribution, conversely the multi stages grinding. At present the fine grinding technology promoted by Xinhai improves the concentrate grate from 61% to 67%.
Weak magnetic iron ore separation process
Weak magnetic mineral could use the strong magnetic mineral separation process after the magnetizing and roasting.
In two stages grinding, stages separation, single weak magnetic flow, fine grinding means adding fine screen regrinding process to separate fine minerals timely and reduce the over-grinding. It improves the capacity of ball mill and concentrate grade by 2%.Successful Case
Ilmenite Beneficiation Plant in Ecuador, a republic in northwestern South America, is one of our successful cases. This is 3D demo Video of the dressing plant created by our company.
A magnetite in Inner Mongolia, the main mental mineral was magnetite with disseminated structure and fine particle distribution. The iron content was about 12-16%. This plant adopted the grinding-weak magnetic process and obtained 65% concentrate grade and 90% recovery rate, but the operation cost is too high after a long time running. It authorized Xinhai to reform the process. Xinhai did not only keep the original indexes, but also reduce the operation costs. Indexes comparison as follow
