Embodiment 1

[0016] As can be seen from the accompanying drawings, a magnetic levitation combined mineral processing method for mixed iron ore, it includes iron ore 6 through ore crushing 1, ore grinding 2, classification 3, dosing and stirring 4, and magnetic levitation separation by magnetic separator 7 5 five process steps are completed;

[0017] Ore crushing 1: Crushing and screening mixed iron ore containing weak magnetic iron minerals, strong magnetic iron minerals and quartzite;

[0018] Grinding 2: Grinding the ore after the crushing step 1, so that the magnetic minerals and non-magnetic minerals in it can be separated into monomers;

[0019] Classification 3: The products obtained in the 2nd step of grinding are subjected to particle size classification, and the unqualified particle size products are returned to repeat the 2nd step of grinding;

[0020] Dosing and stirring 4: Send the qualified particle size ore obtained in step 3 of classification into the mixing tank for slurry...

Abstract

The invention provides a magnetic suspension type combined beneficiation method of mixed iron ores. The magnetic suspension type combined beneficiation method is completed by five technique steps of carrying out ore crushing (1), ore grinding (2), grading (3), medicating and stirring (4), and carrying out magnetic suspension separation (5) of a magnetic separator (7) on iron minerals (6). In the method, uses a flotation agent is adopted to be matched with a special magnetic separator, and weak magnetic selection, strong magnetic selection and reverse flotation are concentrated into a section selection, thus process flow is saved. The magnetic suspension type combined beneficiation method has the advantages of simple technique, short working period and high efficiency and is energy-saving.

Description

technical field [0001] The invention relates to the field of beneficiation of ferrous metal ores, in particular to a beneficiation method of mixed iron ores, in particular to a magnetic levitation combined beneficiation method of mixed iron ores. Background technique [0002] my country has a vast territory and is rich in mineral resources; at present, magnetic separation is generally used to enrich magnetic ores in the world. For example, low magnetic field magnetic separation method is used for strong magnetic ore (magnetite), commonly known as weak magnetic separation method; strong magnetic separation method is used for weak magnetic ore (hematite); The ore can be processed by the combined process of weak magnetic separation and strong magnetic separation. Sometimes in order to increase iron and reduce silicon, flotation method is used to enrich the silicon dioxide contained in it. This is also the most advanced iron ore beneficiation method at home and abroad. , called...
