Embodiment Construction

[0017] as the picture shows:

[0018] The raw ore is crushed to less than 20-30mm, and the non-magnetic gangue is removed by magnetic separation. After pre-selection and fine crushing of the tailings, the ore is ground to -0.074mm by grinding 1, accounting for 35-50%. The pulp is separated into magnetic part and non-magnetic part by wet magnetic separation 1 (weak magnetic field strength magnetic separation). In the magnetic part, the ore is ground to -0.074mm by more than 90% through grinding 2, and the high-grade boron concentrate and iron concentrate are separated by wet magnetic separation 2 (magnetic separation with strong magnetic field strength).

[0019] The non-magnetic part uses a water gravity separator to separate the boron concentrate and gangue with boronite as the main mineral.

[0020] The boron concentrates in the beneficiation are combined into one boron concentrate, and the boron concentrate can be directly used to produce borax by the carbon-alkali method...

Abstract

The present invention relates to comprehensive utilization of mineral resource. Through stepped grinding, stepped magnetic separation, combined magnetic separation-gravitational separation, B and Fe in vonsenite are separated to produce B concentrate, which is used in producing borax, and B-Fe concentrate, which is used in producing iron and steel product and high activity boron-rich sludge. The present invention enriches B2O3 of raw mineral into B concentrate mainly and Fe into B-Fe concentrate through effective separation and provides high-grade and high-activity un-expensive material for boron producing industry while utilizing reasonably the separated Fe concentrate.

Description

Technical field [0001] The invention belongs to the field of comprehensive utilization of mineral resources, in particular to a method for comprehensive utilization of boronite magnetic-gravity separation separation. Background technique [0002] my country is rich in boron resources, B 2 o 3 The total reserves amount to more than 39 million tons. According to the origin of boron resources, they can be divided into three categories: sedimentary metamorphic type (boronite ore, boronite), modern salt lake type (solid ore, liquid ore), and skarn type, and their reserves account for the total reserves in the country 60%, 33%, 1%. Modern salt lake-type mines and skarn-type mines have not been developed and utilized on a large scale due to their remote location and development technical problems. At present, my country's boron raw material industry (borax, boric acid) mainly uses boronite (commonly known as white boron ore) in sedimentary metamorphic boron ore as raw material....
