Embodiment 1

[0035] Raw materials: The ultra-fine ilmenite used in the test comes from a concentrator in Panzhihua area. 2 The grade is 8.89%.

[0036] Such as figure 1 and 2 Shown, a kind of superfine ilmenite pre-enrichment and beneficiation process comprises the following steps:

[0037] (1) Magnetic separation pre-enrichment of ultra-fine ilmenite;

[0038] The magnetic separation pre-enrichment of ultra-fine ilmenite materials includes the first magnetic separation and the second magnetic separation in sequence. The first magnetic separation includes medium magnetic pre-separation I and superconducting magnetic The separation includes medium magnetic pre-separation II and superconducting magnetic separation II in turn, wherein, the tailings of medium magnetic pre-separation I are sent to superconducting magnetic separation I; the concentrate of superconducting magnetic separation I is fed into medium magnetic pre-separation II after regrinding; The tailings of magnetic pre-separat...

Abstract

The invention discloses an ultrafine-grained ilmenite material pre-enrichment and selection process. The process mainly comprises the following two parts of (1) realizing effective pre-enrichment of ultrafine-grained ilmenite by using a ''medium magnetic pre-selection-superconducting magnetic separation'' process to obtain a flotation raw material; and (2) using a ''flotation machine-flotation column'' combined process to select ilmenite after magnetic separation pre-enrichment, and finally acquiring ilmenite concentrate whose TiO2 grade is greater than 47% and a TiO2 recovery rate is greaterthan 40%. The method of the invention has the characteristics of low energy consumption, high efficiency, easy conversion into production practice and the like, and effective recovery of ultrafine-grained ilmenite is realized under a condition of ensuring quality of concentrate products.

Description

technical field [0001] The invention relates to a beneficiation method, in particular to a superfine ilmenite material pre-concentration and beneficiation process for effectively recovering superfine ilmenite by using "superconducting magnetic separation-column flotation". Background technique [0002] Most of the metals containing titanium have good high temperature resistance, low temperature resistance, light weight, high strength, acid resistance, alkali resistance, and good biocompatibility, so they have a wide range of uses. For example, the Hong Kong-Zhuhai-Macao Bridge and the high-speed rail built in recent years, the domestically produced large aircraft, aerospace vehicles and the Jiaolong manned submersible all have titanium presence. [0003] The reserves of titanium resources in the Panxi region of my country account for more than 30% of the world's titanium resources reserves, ranking first in the world. Panxi's recyclable titanium resources mainly exist in th...
